An Adaptive Optimizing Matching Quantization Technique for JPEG
YU Dao-yin · Journal of Optoelectronics·laser · 2000
Having discussed the standard process of JPEG,we put forward an adaptive optimizing matching quantization technique f or JPEG,which is based on choosing different quantization tables according to fr equency characteristics of each image blocks.A serial of experiments is finished ,and the validity and feasibility of the method are verified.
