Patent number: 6885706Abstract: A method for promoting temporal resolution of sequential images is to firstly choose a first visual frame and split it into a plurality of visual blocks according to a predetermined value, then choose a second visual frame. The method then goes to search the second visual frame for mostly resembling respective visual blocks corresponding to every visual block in the first visual frame and estimate the vector displacement of respective corresponding visual blocks of the visual frames. Further, it goes to rebuild a visual frame, estimate the respective pixel values of respective corresponding visual blocks of the visual frames at a time point, combine the pixel values of visual blocks to create the rebuilt visual frame, apply a median-value-filtering procedure upon the rebuilt visual frame, and apply a spatial low-pass filtering procedure upon the rebuilt visual frame, which has undergone the previous procedure.Type: GrantFiled: January 5, 2002Date of Patent: April 26, 2005Assignee: Aiptek International Inc.Inventor: Chiun-Wen Hsu
