Streaming video is becoming increasingly popular among Internet multimedia applications. A robust coding scheme for DCT-based scalable video streaming over the Internet is proposed in this paper. Compared with conventional MPEG4-PGS (fine granular scalable) and progressive FGS(PFGS), the proposed me...

The visual secret sharing scheme proposed by Naor and Shamir provides a way to encrypt a secret black-white image into shares. A qualified group of participants can recover the secret message without using any cryptographic computation. But the original scheme can easily be corrupted by malicious pa...

A blind beamforming algorithm based on a neural network is presented according to the characteristic of cyclostationary signals. This method transforms the question of estimating beamformer weight vectors into the one of computing the SVD of the cross correlation matrix of array input signals and th...

A new faster block-matching algorithm (BMA) by using both search candidate and pixel subsampling is proposed. Firstly a pixel-subsampling approach used in adjustable partial distortion search (APDS) is adjusted to visit about half points of all search candidates by subsampling them, using a spiral-s...

This paper focuses on the general case (GC) airborne bistatic synthetic aperture radar (SAR) data processing, and a new analytical imaging algorithm based on the extended Loffeld's bistatic formula (ELBF) is proposed. According to the bistatic SAR geometry, the track decoupling formulas that convert...
