An enhanced method of image information in the processing of radiation imaging, it relates to handle technology of the image information in processing of radiation imaging. The main steps are: seeking the maximum pixel gray Amax in the gained radiation image A (x ,y) of the measuring object; getting image B (x ,y) by normalizing the image A (x , y), getting image C (x , y) after the image B (x ,y) carrying out mean filtering treatment; getting the image D (x , y) by comparing the difference that image A (x ,y) substrates image B (x ,y) with the border value of pixel point, enhancing its nonlinearity contrast ratio alternation to get the image E (x , y); multiplying the certain strengthening proportion factor alpha (x , y)with E (x , y) , C (x , y) ,getting border strengthen image F(x , y); the strengthen image G (x , y) = (F (x , y) + C (x , y) ) * Amax ultimately. Comparing with the existing technology, the strengthening and handling of image information in this invention has the following advantages, imaging processing speed id quick, the algorithm is simple, imaging is limpid, it removes the noise of image, satisfying the request that the contrast ratio of dark area of scanning image needs to be strengthened. |
