In this paper we propose a multi-sensor image registration approach based on edge-correlation. Firstly, edges of images are extracted and the longer edges are coded by modified Freeman. Secondly initializing correlation of chain code is calculated by integrating correlation coefficient and other methods, then the consistency detection succeeds by relative distance ratio histogram clustering detector...
Serial Digital Interface (SDI) has become a standard video interface gradually. The former methods to implement the SDI cause much costs and low agility. Aiming at the situation that analogue and digital coexist, this paper uses a FPGA-based way to design the SDI, it mainly expounds the scheme of the SD SDI design, and analyses its structures and function of each module, which is implemented by Hardware...
Some registration approaches can fail when percentage of outliers is too high in remote images. We introduce, in this paper, a new approach to improve the robustness of feature extration for automatic image registration. This method is based on long-edge correlation and consistency check. Long-edge correlation extracts a long edge as reference curve in order to increase the percentage of common feature...
A new method based on the edge curvature area extreme-value and the edge correlation for efficient image registration is proposed. First of all, draw some edges from the pending image, set the edge length threshold by using a comparatively large Gauss parameter, save the longer edges only, and mode them with improved Freeman. Secondly, with the Freeman code aforementioned, compute the curvature of...

As for the RST transform in image registration, corresponding formula of box distance transform is deduced. Compared with traditional formula of general affine Hausdorff box distance, search range of distance is reduced. The paper proposes regional Voronoi surface combining comparison of sliding windows when computing Hausdorff distance, characterized by reducing calculating-cost for Voronoi surface...
