Publication number: 20200334543Abstract: A neural network is trained to identify one or more features of an image. The neural network is trained using a small number of original images, from which a plurality of additional images are derived. The additional images generated by rotating and decoding embeddings of the image in a latent space generated by an autoencoder. The images generated by the rotation and decoding exhibit changes to a feature that is in proportion to the amount of rotation.Type: ApplicationFiled: April 19, 2019Publication date: October 22, 2020Inventors: Seonwook Park, Shalini De Mello, Pavlo Molchanov, Umar Iqbal, Jan Kautz
