Abstract

We present a system for interactive shadow editing from single images which includes the manipulations of shape, distribution, sharpness and darkness of shadows according to the features of existing shadows. We first obtain a shadow-free image, shadow boundary and its registered sparse shadow scales using an existing shadow removal method. The modifiable features of the shadow are synthesised from the sparse shadow scales. According to the user-specified shadow-shape and its attributes, our system generates a new shadow matte and composites it into the original image, while also allowing editing of existing shadows. We share our executable for open comparison in community.
