Problems solved by technology

However, the above method is time-consuming to detect the entire area, and in the complex background, due to the interference of redundant information, the detection stability needs to be improved. At the same time, in most cases, the prior information of the target is unknown, so the above method Often can not meet the actual needs

Embodiment Construction

[0044] Now in conjunction with embodiment, accompanying drawing, the present invention will be further described:

[0045]The hardware environment used for implementation is: Intel(R) Core(TM) i3-2350M CPU, 4GB RAM, 2.30GHz, and the running software environment is: Mat1abR2012a and Win7 64-bit operating system. We have implemented the new algorithm proposed by the present invention with Matlab language programming. Experiments are carried out including images of infrared ships at sea, with image sizes ranging from 384×288 to 3086×2865.

[0046] The present invention is specifically implemented as follows:

[0047] Step 1 Obtain the background pixels of the infrared image, and determine the path from the image pixels to the background pixels: first, resize the input image I so that the maximum number of pixels does not exceed 300, and extract the boundary area with a width of γ as the background pixels. Considering that the proportion of target pixels in the infrared image is...

Abstract

The invention relates to a marine infrared target detection method based on a visual attention mechanism. The method, for marine infrared image features, introduces a target detection algorithm basedon the visual attention mechanism, and determines the position of a target in the image by calculating a salience value of each pixel. The method is characterized by, to begin with, extracting an infrared image boundary as a background pixel; then, iteratively updating maximum and minimum pixel values in all paths from a background point to pixel points through a raster scanning algorithm to obtain auxiliary graphs; next, calculating path cost according to the auxiliary graphs to obtain a saliency graph; serving Mahalanobis distance as an image boundary contract image and adding the contract image and the saliency graph obtained in the last step; and then, obtaining the target region position through morphological close operation and binarization operation. The method obtains target saliency information according to the pixel features, thereby greatly reducing marine small target missed detection probability; and the method can effectively suppress noise caused by sea level ripples andsky cloud layers, can highlight the target uniformly and has higher detection accuracy.
