由于光线的影响,两帧图象中的物体无运动,但灰度稍微有变化,这种情况也会影响检测的准确度,所以对两帧图象的象素点进行比较时,可以让它们相减的差值和某个小的数值比较,而不一定就是和0值比较-As the effect of light, two images of an object without moving, but the gray has changed slightly, this will also affect the accuracy of detection, so the tw

Simulations over AWGN and Rayleigh channels, at various signal-to-noise ratios, verify the excellent performance of this novel APEL-turbo scheme. Performance comparisons were carried out between turbo coded APEL, JPEG, and BMP image files. To provi
