Performance analysis of picture's filter wave processing and its enhancement
Huang Run-qin · 2005
Filter wave is a wildly-used but time-consuming technique applied in picture processing.The subdivisionization technology utilizes the procedural locality to speed up matrix operation.The experiment of applying this technology in filter ware processing shows that subdivisionization can not remarkably improve the performance of filter waves.PHIPAC routinization technology is the guideline of advancing counting procedural performance.The article puts forward a method which connects subdivisionization and PHIPAC routinization technology to speed up the picture's filter wave processing,and gives out the size of optimized subdivision.The result shows that this method can effectively optimize the data-visiting pattern of filter wave processing so as to raise the speed of two-dimensional and three-dimentional picture's filter wave processing.
