ABSTRACT:
A method for compressing and reconstructing a color image using principal components transformation. Color image information for a color image is received, and the color image information is converted into intrinsic color information. The intrinsic color information is transformed into transformed information using the JPEG 2000 discrete wavelet transform (“DWT”) algorithm, and the transformed information is quantized into quantized information. The quantized information is encoded into encoded information, and stored. In an additional arrangement, the encoded information is reconstructed using non-pixel data.
