Research of Radiographic Image Enhancement Technology

摘要：

　　Image enhancement has applied widely in biomedical,nondestructive testing,satellite remote sensing and other fields.Especially for the low contrast radiographic images,usually there are some disadvantages for a radiographic image such as the local area image does not show a striking contrast.In order to improve the clearness of low contrast radiographic images,in this paper we combined global adaptive equalization with local dynamic enhancement,then we simulate this enhancement algorithm.The new method will not only effectively increase the global contrast of low contrast radiographic images,but also intensify local details.Because the new algorithms contrast enhancement coefficient function can be adjusted dynamically and locally,the new algorithms are not only adaptive to the process of radiographic images but also having great reference value to the other grayscale images.
