Images are usually transmitted across the Internet using a lossless protocol such as TCP/IP. Lossless protocols require retransmission of lost packets; which substantially increase transmission time. We introduce a fast lossy Internet image transmission scheme (FLIIT) for compressed images which eliminates retransmission delays by strategically shielding important portions of the image with redund...Show More
The system described is a real-time edge detector for use in image processing. The edge-detection algorithm is a 3/spl times/3 Sobel operator and adopts a new circuit of adding to orientation information. The hardware is designed to work at the 10 MHz pixel rate, and will accommodate images of 512/spl times/512 pixels at frames/s with noninterlaced video, or of up to 512/spl times/290 pixels with ...Show More
