ABSTRACT

Masks are used in optical image processing. They are used to generate gradient maps. These maps are applicable to the enhancement of feature extraction and edge detection. Lagrange mask is presented in this letter and criteria for the characterizations of mask performance are given. Through an illustration the performance of the presented mask is demonstrated where it is compared to that of Gabor mask. Results from the illustration support the applicability and suitability of Lagrange mask for the generation of gradient maps from a noise corrupted optical image.
