In image processing, the Wavelet Transform (WT) is largely used. However, time requirements for large two-dimensional image transforms are hard to meet with sequential implementations. Parallel implementation decreases the processing time and allows to reach a real-time operation in image coding. Unfortunately, this parallel coding increases the hardware complexity. We propose an optical implementation of the JPEG2000 compression using a special implementation of the WT. Special attention is paid to propose a simple all optical setup carrying out the optical implementation of JPEG2000 compression for gray-level images. Finally, an adaptation of our technique to colored images is proposed. Wb
