# Signal/Image Processing

Compressed video transmission as used in HDTV and on the Internet requires sophisticated signal and image processing for the storage and transmission of images and video. Research in this area focuses on digital signal and image processing, with an emphasis on image and video compression, joint source channel coding, multimedia applications, and neural networks.

**Joint Source Channel Image Coding for a Power Constrained Noisy Channel :**For a given power constrained Gaussian communication channel, we consider the optimum theoretical allocation of energy per bit for a BPSK transmitter when the performance is measured by end-to-end average quantizer distortion. Choosing the average energy per transmitted bit in conjunction with both the source rate and the channel code rate provides one additional degree of freedom with respect to previously proposed schemes for discrete channels, and therefore achieves higher overall PSNR values for images.

**Robust Error Control in Joint Source Channel Coding for Internet Video :**We investigate robust error control schemes for reducing spatio-temporal error propagation in Internet video transmission due to packet loss.
