Fusion of 2D grayscale images using multiscale morphology

摘要

A scheme for fusion of multi-sensor 2D images based on multiscale morphology is presented in this paper. A point-based registration, using affine transformation is performed prior to fusion. The scale-specific features are extracted from both the images using the morphological towers constructed in course of various types of multiscale filtering. Extracted features are combined to get the fused image. A quantitative measure of the degree of fusion is estimated by cross-correlation coefficient and the error measure obtained by eigenvector fitting between the fused image and each of the constituting images.
