KLT coder for compression of security images

A higher and better precision can been achieved while using more recent security systems and superior detection sensors. It has brought a very rapid increase of data amount as a result. The high resolution (up to ten million pixels) and grey scale images (quantization depth up to 16 bits) accepted in these security applications. A very large volume of image data has been taken during operation of a modern project of automatic monitoring systems. The loss-less compression algorithm has been often required for many applications. Certainly it has not offered achievement of the high compress ratio (up to 2:1 - 5:1 for a special type of images only). The well-known and for the multimedia data optimized lossy methods (JPEG, JPEG 2000) have not been suitable. The hopeful results have been achieved with the tests of wavelets or fractal transforms.
