摘      要：According to the remote sensing image characteristics,a set of optimized compression quality assessment methods is proposed on the basis of generating simulative images.Firstly,a means is put forward that generates simulative images by scanning aerial films taking into account the space-borne remote sensing camera characteristics(including pixel resolution,histogram dynamic range and quantization).In the course of compression quality assessment,the objective assessment considers images texture changes and mutual relationship between simulative images and decompressed images,while the synthesized estimation factor(SEF) is brought out innovatively for the first time.Subjective assessment adopts a display setup — 0.5mm/pixel,which considers human visual characteristic and mainstream monitor.The set of methods are applied in compression plan design of panchromatic camera loaded on ZY-1-02 C satellite.Through systematic and comprehensive assessment,simulation results show that image compression quality with the compression ratio of 4:1 can meet the remote sensins aDDlication reauirements.
