Abstract

The invention discloses a special nonlinear filtering image processing method, comprising: inputting an original image to be processed; performing binomial filtering processing on the original image to generate a first image; performing median filtering processing on the first image, Generate a foreground image; perform normalization filtering and histogram filtering on the foreground image to generate a second image; perform contrast enhancement filtering on the second image to generate a background image; use the difference algorithm to compare and contrast the foreground image and the background image, according to The internal standard extracts the difference between the two images and obtains the target feature attribute; extracts the target feature attribute according to the user standard, obtains the description value of the target feature attribute, inputs the description value into the evaluation software for processing, and obtains the evaluation result; outputs the evaluation result to the user's displayed on the display device.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a special nonlinear filtering image processing method, implementation device and electronic equipment. Background technique [0002] In the detection of appearance defects, feature recognition mainly depends on the core algorithm. The algorithm is the smallest task unit of visual inspection. After an image is given and the ROI (Region of interest, region of interest) detection area is selected, the algorithm starts When the work takes effect, the characteristic targets are extracted by relying on the set detection parameters (coefficients of the function), and filtered and detected, and then the judgment parameters (tolerance thresholds) are used for screening and judgment. At present, a large part of the core competitiveness of the mainstream machine vision technology providers in the market lies in the vision algorithm, and a large part of the core competitiveness of the vision ...
