数字图像增强中灰度变换方法在乳腺X线片中的应用
Application of Gray-scale Transformation of Digital Image Enhancement in Mammograms
摘要
Abstract
As a basic image processing technique, the objective of image enhancement is to obtain a better and more useful visual image in specific applications. Today mammogram is recognized as an effective means of early diagnosis for breast cancer. However, because of limited capacity of the human eye resolution, human negligence and other reasons, a large part of diagnostic information is not available. Therefore, the image enhancement is used to obtain more useful information from the original mammogram. This paper focuses on the gray-scale transformation methods of image enhancement, including linear transformation, nonlinear transformation and histogram equalization, and uses the MATLAB software to realize these methods inmammograms. The results show that the contrast and visual effects of images are improved , which is beneficial to doctors for the microcalcification detection and disease diagnosis in clinical medicine.关键词
