Abstract: We present a method for designing JPEG quantization tables that are tailored for color facsimile transmission. The proposed technique combines results on visual acuity and peak contrast sensitivity of the human visual system with results from rate distortion theory. The new tables yield higher compression ratios for a given visual quality, resulting in shorter transmission times.
