First Claim
Patent Images
1. An apparatus for moving object detection, comprising:
- a frame difference module, for each two successive images of a moving object, computing a frame difference corresponding to said two successive images, said two successive images being a current image and a previous image respectively;
a candidate search module, segmenting inputted said current image into a plurality of homogeneous regions, determining a plurality of uniform blocks from said plurality of homogeneous regions, and then detecting at least a candidate region from said plurality of uniform blocks; and
a moving object fusion module, fusing a plurality of frame differences with said at least a candidate region, aided by a gradual morphing-based technique to obtain a location and a complete outline of said moving object.

Abstract
An apparatus and method for moving object detection computes a corresponding frame difference for every two successive image frames of a moving object, and segments a current image frame of the two successive image frames into a plurality of homogeneous regions. At least a candidate region is further detected from the plurality of homogeneous regions. The system gradually merges the computed frame differences via a morphing-based technology and fuses the merged frame difference with the at least a candidate region, thereby obtaining the location and a complete outline of the moving object.
