| Abstract: | In video error hiding and recovery processing, edge detection and reconstrucUon ot me aamage object are the very important content. Various edge detection technology based on different scenarios have their respective advantages and deficiency, and in this paper, the two classic detection operator have been analyzed and simulated, the performance has been compared. And then a kind of adaptive edge detection technology according to the video frame macro - block noise has been put forward, and the simulation results have been proved its better performance than the two classical edge detection technology. |
