Abstract

The invention discloses a special nonlinear filtering image processing method. The method comprises the following steps: inputting a to-be-processed original image; carrying out binomial filtering processing on the original image to generate a first image; performing median filtering processing on the first image to generate a foreground image; performing normalization filtering and histogram filtering processing on the foreground image to generate a second image; carrying out contrast enhancement filtering processing on the second image to generate a background image; comparing and contrasting the foreground image and the background image by using a difference algorithm, and extracting two images for distinguishing according to an internal standard to obtain a target characteristic attribute; extracting the target characteristic attribute according to a user standard to obtain a description value of the target characteristic attribute, and inputting the description value into evaluation software for processing to obtain an evaluation result; and outputting the evaluation result to display equipment of the user for display.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a special non-linear filter image processing method, realization device and electronic equipment. Background technique [0002] When performing appearance defect detection, feature recognition mainly relies on the core algorithm, which 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 target objects are extracted based on the set detection parameters (coefficients of the function), and detected by filtering, and then screened and judged by the judgment parameters (threshold value of the tolerance). At present, most of the core competitiveness of the mainstream machine vision technology providers in the market is in the visual algorithm, and a large part of the core competitiveness of the visual algorithm is in th...
