The Accuracy Requirement on Optical Filter Used in Image Data Compression
用光学方法实现图像数据压缩时对滤波器的精度要求

We studied the specific requirements on optical wavelet filter in spatial frequency domain for image data compression based on human visual system(HVS) and image perceptual quality evaluation criteria.The upper boundary estimation of the optical wavelet filter in frequency domain was derived and verified by simulation.It will be the bases in designing such kind of optical filter for high quality image data compression.
