In this paper, we propose a hybrid approach for addressing feature-based matching problem. We aim to obtain robust and accurate correspondence between features from image frames under unknown and unstructured environments. The approach incorporates image texture analysis, 2-D analytic signal theory and color modeling. It takes advantage of geometric invariant property in texture and monogenic signal...
Radiometric variations between input images can seriously degrade the performance of stereo matching algorithms. In this situation, mutual information is a very popular and powerful measure which can find any global relationship of intensities between two input images taken from unknown sources. The mutual information-based method, however, is still ambiguous or erroneous as regards local radiometric...
In this paper we present a novel rotation- and affine-invariant image regions detector, coined OSR (Optimum Similar Regions). The two steps of OSR is: first, segment an image with thresholds based on graph theory, these regions of the segmentation results are so called similar regions. Second, the subset of similar regions is confirmed according to the regulation of the similar region’s cardinality...
