Summary: | 碩士 === 國立成功大學 === 電機工程研究所 === 83 === This thesis attacks the problem of motion estimation research
on MPEG(Moving Photographic Experts Group) system. In MPEG
system, motion estimation methodology influences the
transmission speed deeply. This thesis provides a new searching-
times-adjustable algorithm and its architecture. During
calculating motion error, we keep the difference between the
minimum value and the second minimum value. According to the
result, controller judges how many blocks to search in the next
step. Therefore, we can save searching time. Finally, the
algorithm is implemented by FPGAs(Field Programmable Gate
Arrays). The simulation results show a good quality by visual
perception and it reducescalculating amount. Taking real time
into consideration, we proposed an efficient architecture of
lower complexity to implement the algorithm.
