In order to detect the image edge effectively, a new algorithm combining the general grey correlation with the LoG operator is proposed in this paper, which determines whether the discrete sequences have a close relationship or not in terms of the degree of similarity in trends of their curves. Firstly, a 3×3 pixel template is created in the grey image being detected. The center pixel and other eight...
An anaglyph image is typically created by combining the color channels from a pair of stereo images to create a new three-channel image. Presently, when an imaging system encounters a three-channel image (such as a JPEG image), it is treated in a similar fashion as is any other three-color image. There currently is no method for determining whether the image is an anaglyph image or a single-view image...
In this paper, we propose an algorithm for finger vein recognition with less complexity in the image preprocessing phase, where finger vein pattern extraction is not included at all. In the proposed algorithm, we implement phase-only correlation (POC) function at the matching stage with a very simple preprocessing technique. Experimental evaluation of the proposed algorithm using a set of finger vein...
Automatic band-to-band registration of multispectral images is the most critical pre-processing requirement for imaging tasks performed on board satellites, such as data fusion, intra-band coding, change detection, spectral signature based classification, etc. The performance of these tasks depends on the robustness and accuracy of band registration. The a priori information of band misalignment is...
