Abstract: A visual perception of an arbitrary transparent material is imparted to an arbitrary image. In accordance with each element of each deformation map included in a sequence of deformation maps that correspond to a time series, each element of a target image is moved to obtain each deformed image of the time series. Each element of each of the deformation maps indicates a movement direction and a movement amount of each pixel of the target image corresponding to the element.

Abstract: A video of a shadow is automatically generated to create an illusion that a region included in a real object floats above a background and an apparent height of the region with respect to a background region changes with time. A video generation device receives input of a dark region image including a dark region that is a spatial region corresponding to a target object and is darker than a background, and control information for specifying a motion to be given to the dark region, and obtains and outputs a video including a shadow region is obtained and output. The shadow region is obtained by performing mask processing on a motion region obtained by giving the motion to the dark region according to the control information. The mask processing replaces pixels of a mask region at a spatial position corresponding to the target object with pixels brighter than the motion region.
