Motion-Guided Masking for Spatiotemporal Representation Learning

ICCV 2023poster

Several recent works have directly extended the image masked autoencoder (MAE) with random masking into video domain, achieving promising results. However, unlike images, both spatial and temporal information are important for video understanding. This suggests that the random masking strategy that…

Spherical Regression: Learning Viewpoints, Surface Normals and 3D Rotations on N-Spheres

CVPR 2019poster

Many computer vision challenges require continuous outputs, but tend to be solved by discrete classification. The reason is classification's natural containment within a probability n-simplex, as defined by the popular softmax activation function. Regular regression lacks such a closed geometry, lea…
