The tools we developed enable easy processing and annotation of video datasets, including those from other species. Using the identified faces, we generated co-occurrence matrices to trace changes in the social network structure of an aging population. In a 14-year dataset yielding 10 million face images from 23 individuals over 50 hours of footage, we obtained an overall accuracy of 92.5% for identity recognition and 96.2% for sex recognition. We present a deep convolutional neural network (CNN) approach that provides a fully automated pipeline for face detection, tracking, and recognition of wild chimpanzees from long-term video records. Video recording is now ubiquitous in the study of animal behavior, but its analysis on a large scale is prohibited by the time and resources needed to manually process large volumes of data.

When she began the experiment involving the suspension of anti-rejection drugs in March, 2015, doctors said it would eventually include other patients and its findings could potentially affect hundreds of thousands of people, military and civilian alike.Chimpanzee face recognition from videos in the wild using deep learningДaniel Schofield* 1 Arsha Nagrani* 2 Andrew Zisserman 2 Misato Hayashi Tetsuro Matsuzawa Dora Biro 1 Susana Carvalho 1 She also underwent a double hand transplant, but it failed when her body rejected the tissue. She later received new facial features taken from a dead woman. Doctors also had to remove her eyes because of a disease transmitted by the chimp. Nash lost her nose, lips, eyelids and hands when she was mauled in 2009 by her employer's 200-pound pet chimpanzee in Stamford, Connecticut. I believe in the power of prayer and appreciate everyone who is praying for me.' 'I'm just happy I had the chance to help,' Nash said.

The face and the extremities are the most frequently injured parts of the body in war. through its hand and face transplantation program.

The Pentagon, which also paid for Nash's transplant, has provided grants to 14 medical facilities across the U.S. But doctors say that could change if the drugs don't have to be a lifelong commitment.

Because of those dangers, many transplants of non-vital body parts, such as thumbs, are not considered worth doing. The immunosuppression drugs that transplant patients are typically given for the rest of their lives carry such risks as cancer, viral infections and kidney damage. Nash's doctors and the hospital, where Nash is expected to remain at least through the weekend, did not immediately return calls and emails Wednesday seeking comment. If that attempt is unsuccessful, it isn't immediately clear what the next step would be, Sindland said. Sindland said Nash told her the doctors are hopeful they can reverse the rejection by ending the experiment and putting her back on her original medication. Doctors on Monday did a biopsy and determined her body was rejecting the transplant, she said.

Nash recently discovered several unusual patches on her face, Sindland said. The men and women serving our country are the true heroes.' 'I gave it my all and know my participation in the study will still be beneficial,' Nash said in a statement to The Associated Press. Her doctors now hope to reverse the rejection by ending the experiment, Nash's publicist, Shelly Sindland, said.ДЄnti-rejection drugs can have serious side effects, and the military funded the experiment in the hopes the alternative treatment could help those needing transplants after returning from war. Charla Nash had been taking part in an experiment in which doctors at Boston's Brigham and Women's Hospital had tried to wean her off the anti-rejection drugs she had been taking since the 2011 operation.
