Abstract EN
Thousands pictures require a very large amount of storage.
So different techniques of digital image compression is used to reduce the storage requirements for these images.
In this paper an adaptive compression method applied on color image.
Firstly the color image is transformed to the RGB system, and then converts the color data to a luminance/chrominance color space (YIQ).The adaptive compression method is applied on Y.
The image may contain a uniform region and edge region; the uniform regions compress depending on zero-mean coding and the edge region compress depending on Daubechies wavelet transform, then returned the final image to RGB system.
The proposed algorithms has many advantages which make it very efficient, these are, low bit rate, low computational complexity, fast processing and edge preservation with good reconstructed image quality.
