Abstract:
A processing apparatus comprising:means for detecting motion vectors of a plurality of parts having nearly the same consistencies in a first image or a second image from said first image obtained by imaging at a first time and from said second image obtained by imaging at a second time, said means for detecting comprising: means for forming a first high frequency component image and a second high frequency component image and for generating said motion vectors therefrom, and means for averaging said motion vectors; means for extracting a moving boundary between said first image and said second image from differences between said motion vectors of said plurality of parts, said means for extracting comprising: means for dividing said first image or said second image into a plurality of blocks, means for calculating average motion vectors for each block; and means for selecting a target block when said average motion vector thereof is a different sign; and means for estimating a boundary line between two or more objects which appear to be the same object in said first image or said second image, with different motion vectors based on said extracted moving boundary part.
