Abstract

The invention discloses a method for identifying a corresponding infrared target image by using a visible light target image, comprising: adjusting the size of an original image target; extracting HOG features of the original image target; equalizing positive and negative samples; calculating a kernel matrix and a cross-kernel matrix; Eigen decomposition of target domain kernel matrix; interpolation eigenvectors of auxiliary domain; quadratic programming solver transfer eigenspectrum parameters; computing domain invariant kernel matrix; training auxiliary domain SVM using auxiliary domain invariant kernel matrix and labels; using target domain The invariant kernel matrix and label and the auxiliary domain SVM parameters learn the target domain SVM parameters; obtain the target domain SVM parameters, thereby realizing the recognition of infrared targets. The method of the invention can process infrared target images acquired under different collection conditions, and can quickly and effectively identify infrared targets, and the identified results are convenient for other applications of users.

Description

technical field [0001] The invention belongs to the field of image recognition, and in particular relates to a method for recognizing a corresponding infrared target image by using a visible light target image. Background technique [0002] Visual object recognition, also known as pattern recognition about visual images, aims to use theories and methods in the field of image processing and pattern recognition to determine whether there is an object of interest in the image, and if so, give a reasonable explanation to the object, and also determine its location. In computer vision research, object recognition is one of the most basic research problems. In recent years, object recognition technology has received more and more attention, and has been greatly developed and applied in many fields. Including face recognition, pedestrian detection, intelligent video analysis, etc. in the security field; traffic scene target recognition, vehicle counting, retrograde detection, lic...
