By using the base frame it is possible to make continues frames by transferring small amount of data that describes the differences between two continues frames, until a new base frame should be transferred. MPEG compression Another technique that can be used is performing interpolation to guess how the pattern is created from the beginning to the end. The 2D compression JPEG of the static frame is used to compress the base frame, I-frame. The JPEG algorithm is based on spectral analysis of the frame and focusing on the major frequency components of the image. The required image quality sets the compression ratio.
Different applications handle compression with different success with each compression type.
One of the technologies today that might deliver this compression ratio is called WaveLet. This technology used by the Israeli product VDOLive,is chosen by some important Internet Web Sites to use as base for their video services, it seems that this product and this technology are going to lead the market. One of the most attractive aspects of the WaveLet compression is the ability to make a degraded improvement. Video Encoding and Decoding 4.1. Reduced view area with a low detail background should be chosen, objects that are participating in the frames and the camera should avoid fast movements.
