Abstract

A GEM-Foil (Gas Electron Multiplier - Foil) is a basic component of new radiation detectors used mainly in high energy physics and nuclear physics experiments. Optimum performance of such detectors depends critically on the quality of manufacture of such component, because any irregularity in one of the hundreds of thousands of micro-perforations in the plate can induce a spark during operation and damage the detector. Currently, in order to assess the quality of a GEM-Foil, high resolution images are acquired through optical systems to be digitized and then examined by visual inspection. In this work, various techniques to perform binarization of the images of the GEM-Foils are compared, by applying techniques of global and local thresholding, in order to improve the speed and efficiency of processing the images of the GEM-Foils for its quality control. From tests it was found that by simple statistical calculations as the average of the maximum and minimum intensity, using local adaptive thresholding is possible to carry out the segmentation of images in an efficient manner without having to use more complex methods which may involve too large process time.
