Image compensation algorithm for obscured image region in sequence images

To solve the image obscuration in dynamic images, an image block algorithm based inter-rame 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-rame 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-rame gray correlation is presented to compensate the missing image region. The simulation results show the compensation algorithm is effective.
