Algorithm and Application Research on Suppression of DR Image Halo
LE Jian-wei, Song-yang Jin, Xiangdong Li, Xintu Wang · 2009
As for the halo and noise which partly appear too bright or dark in the DR (digital radiography), an improved algorithm of contrast limited histogram equalization is presented in this paper. And it is based on a number of image enhancement algorithm experiments. After enhancing the images collected from different body parts, the algorithm proves to effectively inhibit halo emergence. In addition, VC-based medical image processing software is developed, and also encapsulated into a library function. The software system can assist diagnosis. The effect of image processing and processing time of the system has been accepted during clinical applications.
