In this paper, we develop a low complexity algorithm for spatial overlap detection and characterization that operates directly on the bitstream of motion-JPEG compressed video. Its low complexity and the fact that it does not require video decoding at the sensor nodes make it well suited to multiview distributed video coding applications for wireless sensornetworks.

We consider here image segmentation as a problem of clustering texture features by frequency content. Specifically, we develop a low complexity algorithm for image segmentation that operates directly on the bitstream of JPEG compressed images. Using morphological filtering and watersheds, the algorithm effectively segments an image by combining areas of similar frequency content. Its low complexity and the fact that it does not require decoding makes it well-suited for distributed wireless sensornetworks and image database search applications.
