In order to improve the detection and recognition ability of key target points in weak texture images,based on deep learning,a method of identifying and locating key target points is proposed.The topological feature distribution model for the weak texture images key targets with low light intensity is constructed.The transmittance is used as the detection coefficient,and the pixel distribution is established by combining the prior knowledge of bright channels.The dark primary color fusion and RGB pixel decomposition methods are used to realize the information adaptive enhancement processing of weak texture images with low light intensity.According to the results of noise fusion and matching in the transmission area,the cross combination filter detection and deep learning algorithm are adopted to realize the noise reduction and information enhancement of the weak texture image with low light intensity,thus realizing the key target point detection and recognition of the weak texture image with low light intensity.Simulation results show that this method has high positioning recognition accuracy,with an average value of 0.93,and good image output quality,with an average peak signal-to-noise ratio of 32.87.By comparing the accuracy-recall curve,the performance of this method is superior.
