In this paper, a simple hybrid color compression technique is introduced that effectively mixed between the hard/soft thresholding techniques of block base and the spatial/frequency domains, where the polynomial coding and the wavelet transform exploited. The results showed the optimizing in the compression ratio along with preserving the image quality by mixing hard and soft thresholding.
