A Research on Edge Detection by Marr Algorithm
Marr边缘检测算法的研究

The construction of the LOG template in edge detection by Marr algorithm is researched in this paper. According to the designing criterion, a digitization method using unequal interval sampling combined with non-uniform quantification is proposed. We deduced the general formula of constructing the LOG template and presented the adjusting method of parameters in the formula. The practicability of this method is proved by experiments.
