Evaluation of gray scale changes of CBCT system images in different axis using the DICOM file
The images of dental CBCT imaging systems used in conic shaped beams, stored in the DICOM format, have various applications in the dentistry, including bone density estimation to select the location of the orthodontic implant, bone loss detection and etc. In these systems, unlike CT imaging systems, the resulting images exhibit gray-scale non-uniformity in each of the different axis in FOV. Thi...
متن کاملTopology Based Method of Segmentation of Gray Scale Images
The paper provides a method of image segmentation of binary and gray scale images. For binary images, the method captures not only connected components but also the holes. For gray scale images, there are two kinds of " connected components " – dark regions surrounded by lighter areas or light regions surrounded by darker areas.
متن کاملReconstruction of Gray-scale Images
We present an algorithm to reconstruct gray scale images corrupted by noise. We use a Bayesian approach. The unknown original image is assumed to be a realization of a Markov random field on a finite two dimensional region Λ ⊂ Z2. This image is degraded by some noise, which is assumed to act independently in each site of Λ and to have the same distribution on all sites. For the estimator we use...
متن کاملConnected Component Labeling Algorithms for Gray-Scale Images and Evaluation of Performance using Digital Mammograms
The main goal of this paper is to compare performance of connected component labeling algorithms on grayscale digital mammograms. This study was carried out as a part of a research for improving efficiency and accuracy of diagnosing breast cancer using digital mammograms. Three connected component labeling algorithms developed by Jung-Me Park [8], Kenji Suzuki [16] and Kesheng Wu [9], were used...
متن کاملAn Adaptive Threshold Method for Gray Scale Character Images
Gray-scale document images are binarized in order to perform optical character recognition (OCR). To perform this binarization, a variety of techniques have been proposed for performing threshold selection. Most of these are based on the intensity distribution of the image regions. However, when the spacing between two lines is very small, it is difficult to produce high quality characters usin...
