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...
