COUNTING METHOD FOR TRACK IMAGES USING CANNY EDGE DETECTOR

摘要

The present invention relates to a track image counting method using track edge detection for counting tracks of a nano unit using an image processing technique. The track image counting method includes optimizing an image including an input track, Track correction and track detection, recovering a damaged track of the corrected track, and counting the total number of tracks including the number of overlapping tracks using the number of tracks detected and the size information of the recovered track Wherein the step of restoring the damaged track includes a step of detecting a contour corresponding to an edge of the track and converting the contour into a line segment having a predetermined length, And a model predictive restoration step of estimating and restoring a model of a track by applying a RANSAC algorithm to a line segment satisfying the condition, , The track contour detection step is to detect the contour of the track using a canny edge detector.;
