In the most common standard coding schema of the image, coder has greater complexity than the decoder, usually 5-10 times higher. In wireless sensor networks is the opposite, the coder is implemented in a battery feed device, having so very limited power resource, while the decoder is typically implemented in a powerful computer. The paper will focus on a combination of wavelet technique with algebraic GPCA method, realizing an improvement of traditional wavelet technique, providing a suitable

The proposed method, unlike other existing methods, takes into account the structure of multi-modal data, except the correlation in 1 D and 2 D it takes in consideration correlation between color channels. The method gives a significant improvement in the PSNR values reaching an average of 15% compared with traditional wavelet compression.
