[Program doc] dm642.ZIP DL : 0: 在本文中，我們首先實作了一個針對壓縮視訊（像是 H.264/AVC）之畫面解析度改善的方法。接著，我們分析這個方法的模擬結果。-In this thesis, we first implement a spatial resolution enhancement algorithm for H.264/AVC compressed videos. Based on the analysis of the simulation results, we identify a few shortcomings of this algorithm, like some visual artifacts in the enhanced videos and some problems caused by scene change and fast motion. Then, we propose two methods to suppress these artifacts, including adding a median regularization term in the spatial-domain and using a median filter in the temporal domain. We also propose two methods, a global method and a local method, to overcome the scene change and fast motion problems. With these modifications, the artifacts and problems are suppressed significantly.
