Abstract
This work proposes a tool based on texture analysis to characterise incorrect point correspondences in underwater image pairs. Interest point correspondences are first detected through region correlation, obtaining pairs of matched points in both images. For every pair of points, their textural characteristics are computed. These textural properties are stored in two corresponding characterisation vectors, which are then compared by means of similarity measures. This measure can be considered as a reliable threshold for outlier rejection. Experiments with real underwater images were carried out.
