This thesis is to introduce a new arithmetic design and workflow,algorithmic analysis, a basic calculation procedure of a new algorithmic and the effect of this arithmetic and compare these with that of the traditional arithmetic. This arithmetic utilizes the positional relation in data windows and take a position relationship and a correlation between two neighbor data windows into account. In the operational process, this arithmetic reserves the tactic order information of previous data window as the referential foundation of the next window for sorting order. Thus two contiguous medium filter in traditional arithmetic can be combined as one and the frequency of the comparative operation in medium filtering decreased. This arithmetic is able to simplify the complex degree of traditional arithmetic and combine mean filter with medium filter, syncretize these two independent arithmetic into one to speed up the operation effectively and reduce the influence of noise on image.
