Gait analysis has been around for years, but now it is going mainstream, using precision imaging to measure details the eye can't perceive.

"One of the biggest breakthroughs in the early days of gait recognition was realising that you can recognise someone by their silhouette," says Patrick Connor with Stepscan Technologies in Canada. He is talking about gait energy imaging. This involves taking a series of snapshots of a person's profile as they walk, usually from the side, and merging them into a single image, each unique to their owner. "The head' s in the same place and the torso' s in the same place and you get this kind of blurry limb movement," says Connor. With its help, some systems now can identify 90 percent on enormous databases of tens of thousands of people. It is also beginning to work with less than ideal imagery. Computer scientists in Portugal showed that they could reliably recognise people walking under a downward-pointing camera solely from their shadows. This may mean drones can carry out covert gait analysis - on sunny days, at least.

More conveniently, if people want to be identified, for airport security, for example, there is no need to go to the trouble of measuring silhouettes, as in gait energy imaging. Instead, someone might be asked to wear sensors that would feed back precise information about their movements. Computer scientist Maria De Marsi co at the Sapienza University of Rome uses this method to recognise people from the information sent from the accelerometer inside a standard smartphone as it jerks around in their hand or pocket as they walk. Her team has built a prototype smart door that opens when it recognises an approaching person in this way. In principle, this is much easier than, say, pausing to scan an iris or fingerprint at a checkpoint.

Gait analysis may prompt thoughts of face-recognition technology but it could be even more powerful, since it can work with lower resolution pictures and is much harder to avoid than face recognition systems. But gait analysis is nowhere near as widely used as face recognition yet. This is mainly because it requires a series of sequential pictures that cover the seven stages of walking, as each leg moves and lifts. Processing these images requires serious computing heft and most gait analysis systems don't have enough of this to work in real time, but a crucial requirement for use in law enforcement is that the systems can recognise those they want to apprehend quickly enough to give authorities a shot at detaining them.

For this year's brief, we're asking students to show through a series of five to ten images the first part or earliest stage of something. Be it following a new life, sharing the start of someone's day, following the preparations and beginning of a particular occasion or celebration, or revealing the promise of new technology, the story, approach and photographic style can be in any genre.

Your images can be taken on any device, shot in any style-be black & white or colour-and approached from any angle you feel is best. While innovative responses are encouraged, photographers must stick to the brief.

The Competition is open to all students of photography from World Photography Organisation's selected Universities. All entries must confirm, on application, their acceptance of the rules of the Competition and these Terms and Conditions. Entries must be submitted by 13:00 GMT on 29 November 2025. By entering the Competition, each Entrant agrees and acknowledges that World Photography Organisation (WPO) is permitted to receive his/ her registration data. All personal information will be used by WPO in accordance with its privacy policy.

Students are required to submit Five to Ten images responding to a brief. To enter, students must ensure their institution is registered and images are submitted via www.worldphoto.org. If your institution is not registered yet, you can registerhere. For a list of participating institutions, please see here.

Your entry may feature manipulation, but where entries are manipulated, the extent of which must be described in the image description section when submitting. For the avoidance of doubt, all Entries must originally be from either an analogue or digital photograph which may have then been manipulated. Computer generated content cannot be the origin of the entry. Should a question arise through the judging process regarding the extent of your entry's manipulation, you may be requested to submit the original photograph and image file to verify.

The overall winning university is given Sony digital imaging equipment worth approximately €30,000 as well as the flights and accommodation for one student and one tutor to the awards ceremony in London.

Boiled chicken, rice (cook) with chicken oil, and dip make up the simple and delicious Hainanese chicken rice, which has provided lingering nostalgia for overseas Chinese in Southeast Asia. More than a century ago, large numbers of Hainan people spread across Southeast Asia, taking them their native dish Hainanese chicken rice. As time went by, Hainanese chicken rice gradually became a popular dish in Southeast Asian countries. Hainanese chicken rice not only (satisfy) the diners, but also embodies the taste of home for overseas Chinese from Hainan. It is a vivid (reflect) of cultural exchanges of people along the Belt and Road countries from history to reality.

As Miller defines it, hope is not a naive approach to seeing the world, where we ignore problems and engage in "wishful thinking". Instead, hope is a complex response, (involve) "feeling, thought, action, vision, a life force, and a way of seeing or being". Having hope, as opposed to living in fear, he argues, helps us to see possibility in present-day circumstances and not become overwhelmed. People who feel hopeful are good problem-solvers, more engaged and productive at work, more (create) and adaptable, and better at recovering from adversity. For these reasons and others, inputting more hope into ourselves means we (equip) to handle problems more smoothly.

A group of STEM students from New Britain High School teamed up to build fully-functioning electric carts for families who are not able to afford adaptive wheelchairs. The student volunteers (spend) months working on these cars. On the day the students completed the carts, Kelicia and Mosiah's families went to New Britain High School to test them out for the first time. When each child got into their brand-new cart, their faces lit up. The cool, red electric cars gave kids with disabilities a way (move) around independently with a huge smile on their face. It was the single moment the builders looked forward to most.

The guard remained2 as tourists approached to touch the horse's nose, her professional manner unshaken. However, everything changed when she3 two familiar faces in the crowd. Her parents, holding umbrellas, made their way to the front. Her father, dressed in a dark coat, gently stroked the horse and spoke softly to his emotional daughter. She struggled to hold back her4, but her feelings were clear for all to see.

Her mother stepped closer, asking her a question. The guard gave a slight5 before her emotions overcame her. Tears rolled down her cheeks, and she quickly wiped them away with her white gloves. In spite of the rain, a kind member of the crowd offered to take a picture of the family. The parents stood6 on either side of the horse, their faces glowing. After the photo was taken, they quietly stepped aside, allowing their daughter to return to her duties.

The tourists, unaware of the emotional moment that had just occurred, continued posing with the guard and her horse. The guard, though moved by her parents' surprise visit, soon7 her professional posture. Her father, from a distance, took another photo of her sitting upright on the horse, focused and8 to her role.

The rain9. The guard stood taller than before. The brief visit from her parents reminded her of what truly matters — the unshakable love and pride shared within a family. In the soft rain, her sense of duty and her family's unwavering support came together, giving her strength to carry on with dignity and10.

When I was in middle school, my social studies teacher asked me to enter a writing contest. I said no without thinking. I did not love writing. My family came from Brazil, so English was only my second language. Writing was so difficult and painful for me that my teacher had allowed me to present my paper on the sinking of the Titanic by acting out a play, where I played all the parts. No one laughed harder than he did. So, why did he suddenly force me to do something at which I was sure to fail? His reply: "Because I love your stories. If you're willing to apply yourself, I think you have a good shot at this."

Encouraged by his words, I agreed to give it a try. I chose Paul Revere's horse as my subject. Paul Revere was a silversmith in Boston who rode a horse at night on April 18,1775, to Lexington to warn people that British soldiers were coming. My story would come straight from the horse's mouth. Not a brilliant idea, but funny, and unlikely to be anyone else's choice. What did the horse think, as he sped through the night? Did he get tired? Have doubts? Did he want to quit? I sympathized immediately. I got tired. I had doubts. I wanted to quit. But, like Revere's horse, I kept going. I worked hard. I checked my spelling. I asked my older sister to correct my grammar. I checked out a half-dozen books on Paul Revere from the library. I even read a few of them. When I handed in the essay to my teacher, he read it, laughed out loud, and said, "Great. Now, write it again." I wrote it again, and again and again. When I finally finished it, the thought of winning had given way to the enjoyment of writing. If I didn't win, I wouldn't care.

The Great Wall of China is one of the greatest wonders of the world. With history of more than 2,000years, some parts of the Great Wall have disappeared., it is still a very popular place of interest.

It is the (long) wall ever built, is about 8 meters high. The top is 8 meters wide and it is even (wide) at the bottom. It is made of stone and brick. People built it hand and it took a long time to finish.

No one knows (exact) when the building of the Great Wall was started. It is believed the wall was built(protect) parts of the country in the old days. It also made people live a safer life.

Today, many of the visitors go to see the Great Wall. When they stand on top of a tower and look down on this wall, they can't help (say), "Wow, that's fantastic!"

Instead of looking at nature, I checked my e-mail. Instead of paddling (划桨) an old boat, I1 my Twitter feed. Instead of reading great novels, I2 reading four newspapers each morning.

And that was the problem: I was acting3 I were still in the office. My body was on vacation but my brain wasn't.

So this year I made up my mind to try something4: getting away from the Internet. I knew it wouldn't be easy, since I'm not good at self-control. But I was determined. I started by5 the iPad to my wife, so I was6 to carry out my plan. Largely7 from e-mail, Twitter and my favorite newspaper websites, I had8 ways to connect to the world except for radio and how much radio can one listen to, really? I had no choice but to do what I had planned to do all along: read books.

This experience has had a happy ending—for now, at least. With9 and the strong support of my wife, I succeeded in my vacation10 against the Internet. I finally11 that it was me, of course, not the iPad, that was the problem.

I knew I had12 when we passed a Starbucks and my wife asked if I wanted to stop to use the Wi-Fi. "Don't need it," I said. However, as we return to post-vacation situation, a test begins: Can I continue when I'm back at work? And I don' t plan to give up my convenience13. But I hope to14 the temptation (诱惑) to check my e-mail every five minutes, which often leads to following my Twitter feed.

A vacation is supposed to help you reset your15 to become more productive(高效的). Here's hoping this one worked.
