Deepfake Detection: Challenge Accepted

Advances in methods to generate photorealistic but synthetic images have prompted concerns about abusing the technology to spread misinformation. In response, major tech companies like Facebook, Amazon, and Microsoft partnered to sponsor a contest hosted by Kaggle to mobilize machine learning talent to tackle the challenge. With $1 million in prizes and nearly half a terabyte of samples to train on, this contest requires the development of models that can be deployed to combat deepfakes....

Everybody Dance Faster

Check out the repo and the video! “Everybody Dance Now” offers a sensational demonstration in combining image-to-image translation with pose estimation to produce photo-realistic ‘do-as-i-do’ motion transfer. Researchers used roughly 20 mins of video shot at 120 fps of a subject moving through a normal range of body motion. It is also important for source and target videos to be taken from similar perspectives. Generally, this is a fixed camera angle at a third person perspective with the subject’s body occupying most of the image....

Editing Images With Cyclegans

GANs represent the state of the art in image-to-image translation. However, it can be difficult to acquire aligned image pairs to learn the mapping between image domains. CycleGANs introduced the “cycle consistency” constraint to learn to transfigure images, transfer style, and enhance photos from unaligned source and target domain samples. This technique has been used to render historic black & white images in full color or to represent an image in greater resolution but here, we explore applications in agriculture....
