first_imgGo back to the enewsletterAfter a successful 2018 program, organisers of the Luxperience travel show have announced the event will return to the International Convention Centre, Sydney, from 7–10 October 2019. Now in its eighth year, Luxperience remains at the forefront of the high-end experiential travel market, bringing together industry leaders for three days of inspiring, meaningful connections. In 2019, Luxperience attendees can expect an innovative program, new products, glittering events and insights into luxury travel trends.“After fine tuning our event within the Diversified Communications fold, we were delighted with the success of this year’s Luxperience,” said Michelle Papas, Event Director of Luxperience. “Each year we survey all attendees about their experiences at the show. The results for Luxperience 2018 were outstanding and demonstrate our commitment to year-on-year improvement.”In 2018 the Luxperience program was reimagined and enhanced to create what is now widely acknowledged as a must-attend event. With an expanded team, a new home and a revitalised events program, the seventh edition of Luxperience has set the standard for future events. Hundreds of exhibitors and buyer delegates from around the world, thousands of one-on-one meetings and millions of dollars worth of new business all come together in the only trade show of its kind in the South Pacific region.Key highlights from attendees:97% of buyers were satisfied with their experience96% of buyers are likely to recommend Luxperience91% of buyers are likely to return for Luxperience 201995% of exhibitors were satisfied with their experience91% of exhibitors are likely to recommend Luxperience84% of exhibitors are likely to return for Luxperience 2019Luxperience’s focus remains on building meaningful business opportunities and relationships and is currently seeking expressions of interest from suppliers of luxury and experiential travel. Premium travel specialists who service the needs of discerning clients are also being sought from around Australia and around the world.Businesses interested in exhibiting opportunities or attending as a buyer should email luxperience@divcom.net.au.More details to be released over the coming months.Go back to the enewsletterlast_img read more

New software can track many individuals in a crowd

first_img Software tracks marathon runners. For a group of more than about 10 people, a perfect mathematical solution to the formula is impossible, because of the number of targets and interactions between them. So the team uses an iterative algorithm to produce a slightly rougher but easier-to-calculate prediction of each person’s location frame by frame. “It’s not feasible to find an exact solution for a large number of targets,” says Afshin Dehghan, a computer scientist who conducted the work with Mubarak Shah while at the University of Central Florida in Orlando. “We introduced a new technique that is actually popular in other areas, like math.” (It’s a version of what’s called the Frank-Wolfe algorithm, if you’re curious.)To test their method, the researchers analyzed nine crowd videos that had been used in previous research, covering marathons, commuters, a crosswalk, a train station, an airport, and a Hajj pilgrimage. The crowd sizes ranged from 57 to 747 people. By one measure, the program’s accuracy at tracking everyone in a video ranged from 67% to 99%. That performance matched or greatly exceeded five comparison algorithms—all of which tracked people one by one. In 2015, more than 2000 people died in a stampede during the Hajj pilgrimage in Saudi Arabia. In 2013, two terrorists deposited backpacks carrying bombs at the Boston Marathon and slipped away, leaving three spectators to die. If technology could in real-time track and analyze the movement of individuals in dense crowds, we might better predict dangerous pileups or spot suspicious behavior, saving many lives a year. A pair of researchers has just taken a large step in that direction, writing software that for the first time can track hundreds of people in a crowd simultaneously.Following the paths of many individuals at the same time is enormously difficult, even for humans. Previous computer-based efforts to analyze dense crowd movement have focused on tracking one individual at a time in recorded video. But there are problems with that method. First, you have to run the programs over and over again for each person you want to track. Second, the programs tend to identify people in each frame of a video based on appearance—but heads and faces can be hard to distinguish from above, especially in tight crowds and low-resolution video. The new research, which will be published in IEEE Transactions on Pattern Analysis and Machine Intelligence, finds a way to increase both the efficiency and accuracy of tracking a person, enabling a software program to finally follow many people at the same time.The trick involves predicting where an individual will go next. The researchers wrote a mathematical function that analyzes five factors, based on previous frames of a video, to anticipate where each person will be in the current frame. One is appearance: Which patches of pixels resemble the target from the previous frame? Another is target motion: Where could the target be based on speed and direction? A third is neighbor motion: If the target is obscured, the program guesses on location based on the motion of the person’s neighbors. Fourth is spatial proximity: The program won’t guess that two people are in the same place, standing on top of one another. And last is grouping: If the program identifies a few people walking in a group, it will assume that they’ll retain the same formation.

Dehghan et al., IEEE Transactions on Pattern Analysis and Machine Intelligence PP, 99 (24 March 2017) © IEEE Incorporating collective movements was key to the program’s success. “There are group dynamics at play when you’re with other people, especially in a dense situation,” says Aniket Bera, a computer scientist at The University of North Carolina in Chapel Hill, who studies crowd behavior but was not involved in the work. “That information has been exploited in this paper.”Hamid Rezatofighi, a computer scientist at the University of Adelaide in Australia, who has worked on multitarget tracking, says the technique is interesting. But he questions its practicality, because a user has to manually select targets to track. That means at the start of a video, users have to click on each person they want to follow.And currently the method does not work in real time when tracking hundreds of people—it can take close to a second per frame to finish the needed calculations—but Dehghan notes that “the code has a lot of room to be optimized.” He’s hoping to release it publicly.“There are many applications for tracking individuals in a crowd,” Dehghan says. You might analyze flow to design public spaces better and prevent overcrowding or bottlenecking, or program rules that spot anomalous behavior in security videos, such as lingering or stalking or erratic walking. Crowds form not just at marathons and pilgrimages, of course, but at concerts and political rallies and soccer games. In fact, the research was partially funded by the Qatar National Research Fund, as Qatar will be hosting the 2022 World Cup and wants to assure crowd safety. (Where should entrances and exits be placed? Can a terrorist be identified before detonating a bomb?)And humans aren’t the only ones to flock together. The same technique, Dehghan says, could be used to follow members of herds of animals or schools of fish for scientific research. Or cells in medical imaging to diagnose disease or understand healthy functioning. “Tracking in dense crowds is a relatively unexplored problem,” he says.last_img read more
