Image compensation algorithm for obscured image region in sequence images

To solve the image obscuration in dynamic images,an image block algorithm based inter-frame predictor is presented to detect missing image region in sequence images and a pixel inserted compensation algorithm based on gray correlation is given.The inter-frame predictor based on image block algorithm can be used to detect the missing image region in sequence images,which is caused by a partially obscured CCD.A method using modified pixels with inter-frame gray correlation is presented to compensate the missing image region.The simulation results show the compensation algorithm is effective.
