Latest Patents

One of his latest patents involves a method and apparatus for processing video. This innovation identifies image features of an object within a frame of video footage and tracks their movement throughout the footage to determine their trajectory. The analysis of these tracks allows for the determination of a texture map, which can be interpolated to create an unwrap mosaic for the object. This process can be iterated to enhance the mosaic further. Additionally, effects or artwork can be overlaid on the mosaic, which can be warped and combined with layers of the original footage, allowing the effect to move with the object's surface.

Another notable patent is a method and system for video indexing and video synopsis. This system generates a synopsis video from a source video by selecting at least three different source objects according to defined constraints. Each source object is a connected subset of image points from at least three different frames of the source video. The synopsis video displays selected synopsis objects at their respective times and color transformations, allowing for a simultaneous display of points derived from different times in the source video.
