In this paper, we present a perceptual distortion measure that predicts image integrity far better than mean-squared error. This perceptual distortion measure is based on a model ...
In this paper we present a full-custom VLSI design of highspeed 2-D DCT/IDCT processor based on the new class of time-recursive algorithms and architectures which has never been i...
Stereoscopic sequence compression typically involves the exploitation of the spatial redundancy between the left and right streams to achieve higher compressions than are possible...
This paper discusses the feasibility of coding an "undetectable" digital water mark on a standard 512*512 intensity image with an 8 bit gray scale. The watermark is capa...

The development of a system able to detect and track moving people is described. Given a sequence of timevarying images, the goal is to count the number of people crossing a count...
Periodic or symmetric extensions are commonly used for processing images and other finitelength signals with a paraunitary Alter bank (PUFB).Unlike infinite-length signals, PUFBs ...
