Abstract

The invention provides an improved image registration method based on a continuous domain ant colony algorithm. The improved image registration method comprises the following steps: S1, determining atemplate image and a sensing image; s2, extracting a graphic contour of the template image to obtain a template pixel point set T; extracting a graphic contour of the sensing image to obtain a searchpixel point set E; s3, quantifying the similarity between T and E; s4, segmenting the template image to generate a region of interest; and S5, matching the region of interest with the sensing image, and finding out the measurement with the maximum similarity by adopting a continuous domain ant colony algorithm to achieve image registration. According to the improved image registration method basedon the continuous domain ant colony algorithm, the similarity of the pixel point set is quantified, then the continuous domain ant colony algorithm is adopted to find the measure with the maximum similarity, registration of the segmented template image and the sensing image is achieved, the registration precision is improved on the premise that the registration speed is guaranteed, and problem that an existing image registration method is not high enough in registration precision is solved.

Description
