Abstract
Based on the least mean square error criterion at the edge position, a new algorithm is presented to obtain a class of optimal edge-preserving hybrid filters that include the Lee (1980) additive filter and the gradient inverse weighted filter. As a result, we show that the gain of the Lee additive filter is not optimal and derive the optimal form of this filter. In addition, some examples are given
