Summary:The invention relates to the technical field of image processing, in particular to an anti-wear hydraulic oil pollution particle detection method. The method comprises the steps of obtaining texture similarity indexes of each pixel block and an adjacent pixel block according to gradient amplitudes of pixel points in each pixel block in a ferrographic image of hydraulic oil and contrast ratios of the pixel blocks, and then combining the pixel blocks to obtain image blocks; obtaining each flow direction point pair in the window corresponding to each pixel point according to the gradient direction of the pixel point in the window corresponding to each pixel point; determining the selection necessity of each flow direction point pair according to the number of the flow direction point pairs in the window corresponding to each flow direction point pair and the edge extension line corresponding to each flow direction point pair, and further obtaining each target area; and obtaining an enhanced image according to th
