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 ide

Median filter replaces the intensity value in each pixel by the local median taken over a local n x m processing window where is a local m x n window around the pixel (x,y) in the image g (to be processed), and MED is the median value taken over the
