Perceptual Biases in the Interpretation of Non-Rigid Shape Transformations from Motion

Vision
Most existing research on the perception of 3D shape from motion has focused on rigidly moving objects. However, many natural objects deform non-rigidly, leading to image motion with no rigid interpretation.
