A converse and contrast rescaling method for x-ray images

The contrast of intensity in x-ray images prior to image processing but contrast process dose not include any degradation of images. Many x-ray images are damage due to converse and contrast process. This paper proposed the technique for converse the gray level from the x-ray projection images and contrast-stretching the images. The characteristic of the objects are clearly appearing by this technique. Otherwise, the technique is suitable for the large variety of gray tones of image data. The experiment section uses the CNR to verify the contrast of images. This experiment results are satisfy as a preprocess prior to reconstruction process.
