Embodiment Construction

[0038] The present invention will be described in detail below in conjunction with specific embodiments.

[0039] Aiming at the urgent problem to be solved in solid nuclear track images, a method of adhesion separation of dense solid nuclear tracks is proposed. The method firstly enhances the contrast of the track microscopic image; then uses the extended maximum segmentation method to segment the image to obtain the initial track target; then uses the mathematical morphology and area ratio method to separate the cohesive track inside the image; Special adhesion separation of tracks at the center and single tracks without holes. The algorithm process diagram is as follows figure 2 shown.

[0040] (1) Image contrast enhancement

[0041] The track granularity in the image varies greatly, and most of the tracks are gray-black, while some small tracks are light gray, which is close to the gray level of the background impurities. Therefore, a simple and fast image enhancement m...

Abstract

The invention discloses an adherence separation algorithm of intensive solid state nuclear tracks. The adherence separation algorithm of the intensive solid state nuclear tracks includes the following steps: (1) image contrast enhancing; (2) expanding maximum value separation; (3) area proportion adherence separation; and (4) special adherence separation. The adherence separation algorithm of the intensive solid state nuclear tracks can effectively solve the problems of removing of noise and non-track impurities in track images, processing of the tracks which are large in granularity difference, accurate separation of the tracks which are serious in adherence and uneven in inner gray scale, and meanwhile promote the speed of adherence separation.

Description

technical field [0001] The invention belongs to the technical field of image processing, and mainly relates to a dense solid nuclear track microscopic image adhesion separation algorithm, which is designed using a mathematical morphology method. Firstly, the contrast is enhanced to process the light gray small track, and then the track is segmented to obtain the track. The basic profile and removal of non-tracking impurities, and finally adhesion separation to obtain an accurate profile of a single track. Background technique [0002] When high-energy charged particles enter solid materials, they will leave nanoscale radiation damage along their tracks, and after etching, solid nuclear tracks can be formed that can be observed with a microscope. The type, energy spectrum and yield of charged particles can be determined by measuring the number, size, shape and depth of the tracks. There are tens of thousands of tracks on the track film, with diameters ranging from a few micr...
