【 摘 要 】

In this paper, we present the performance analysis of adaptive bilateral filter by pixel to noise ratioand mean square errors. It was evaluate changing the parameters of the adaptive filter half widthvalues and standard deviations. In adaptive bilateral filter, the edge slope is enhanced bytransforming the histogram via a range filter with adaptive offset and width. The variance of rangefilter can also be adaptive. The filter is applied to improve the sharpens of a gray level and colorimage by increasing the slope of the edges without producing overshoot or undershoots. Therelated graphs were plotted and the best filter parameters are obtained.
