Common compression systems treat color image channe ls similarly. Nonlinear color models like Hue&Saturation& Value/ Brightness/ Luminance/ Intensity (HSV/ HSB/ HSL/ HSI) have special features for each channel. In this paper a new hybrid compression system is proposed for encoding color images in HSI color model. The proposed encod ing system deals with each channel with a suitable compression techn ique to obtain encoded images with less size and high decoding quality than the traditional encoding methods. There are th ree encoding techniques will be mixed in the propos ed system; object compression technique for the hue channel, Luma (Y) Intensity (I) Difference (D) for saturation, and the standard JPEG2000 encoding technique for the intensity channel. The p roposed system results demonstrate the proposed arc hitecture and give considerable compression ratio with good decoding q uality.
