Embodiment Construction

[0069] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0070] The present invention proposes a first embodiment, such as figure 1 , figure 2 , image 3 and Figure 4 Shown, an image recognition method comprises the following steps:

[0071] S01. Image matching step: use the image matching method to perform similarity matching between the template array and all arrays of regions to be matched in the image to be tested, and assign each similarity value to the pixel points in the corresponding region to be matched to obtain similarity value image;

[0072] S02. The first filtering step: performing first filtering on the similarity value image by using a similarity threshold to obtain a first filtered image;

[0073] S03. Region identification step: Obtain the region contours of continuous similarity...

Abstract

The present invention belongs to the image recognition field and provides an image recognition method, an image recognition system, an automatic focusing control method and an automatic focusing control system. The image recognition method includes the following steps of: image matching: an image matching method is adopted to perform similarity matching on a template array and all to-be-matched region arrays in an image to be tested, and similarity values are respectively assigned to pixels in corresponding to-be-matched regions, so that a similarity value image is obtained; first filtering: the similarity value image is subjected to first filtering through using a similarity threshold value, so that a first filtered image is obtained; and region identification: the outlines of continuoussimilarity value regions in the first filtered image are obtained through a region growing method, so that the contour of a subject in the image to be tested is obtained. With the methods and the systems of the invention adopted, the contours of subjects in images can be accurately identified, and particularly, the contour of a subject in an image to be tested which contains a plurality of items in different shapes can be accurately identified.

Description

technical field [0001] The present invention relates to the field of image recognition, more specifically, to an image recognition method and system, and an automatic focus control method and system. Background technique [0002] A method for extracting SAR image target outline based on the Snakes model is mentioned in the prior art, including based on the half-point noise model, using the local statistical characteristics of the image, selecting a window as a local area, and using the Lee filter algorithm to filter; clutter suppression Conditional judgment and amplitude adjustment are performed on the gray value of each pixel of the final image, and the gray scale transformation is performed on the image after clutter suppression by using the piecewise linear gray scale transformation method; The feature establishes the energy function, and by solving the energy function minimization problem, the target contour curve is obtained. [0003] The method involves filtering, gra...
