The invention discloses a no-reference laser interference image quality evaluation method, which belongs to the field of image processing, and comprises the following steps: constructing a support vector regression device; the support vector regression device comprises a local feature extraction module for performing local information estimation on an input image to obtain local information estimation features; a natural scene statistical feature extraction module which is used for performing spatial domain-based natural scene statistics on the input image to obtain natural scene statistical features; a quality scoring module which is used for scoring the quality of the input image according to the local information estimation characteristics and the natural scene statistical characteristics; inputting the interference image data set into a support vector regression device for training to obtain a trained support vector regression device; and inputting the to-be-evaluated image into the trained support vector regression device for quality evaluation to obtain a quality score of the to-be-evaluated image. According to the method, distortion of the laser interference image can be truly described, and the quality loss of the laser interference image can be accurately reflected on the basis of not needing a reference image.
Description
technical field [0001] The invention belongs to the field of image processing, and more specifically relates to an image quality evaluation method without reference laser interference. Background technique [0002] The complex optical and electrical responses produced by the laser in the optical device (lens and aperture) and the image plane will produce high-brightness spots of various shapes in the image, which will significantly reduce the image quality; at the same time, the interference spots will affect the key information of the image The occlusion of the object, especially the occlusion of the target, will seriously affect the detection and recognition performance of the information processing system. In-depth analysis of the laser jamming effect of the image and a quantitative index system can provide technical support and theoretical basis for the research and development of the laser jamming system, which has important military value and practical significance. ...
