Abstract
Embodiments of the present specification provide an image enhancement processing method and device for an X-ray defective weld image. In the image enhancement processing, a first pixel value of each pixel in a defective area of the X-ray defective weld image as a gray image is obtained as a brightness value, and then a color mapping processing based on contrast enhancement is performed on each pixel in the defective area according to the obtained first pixel value, to obtain an enhanced X-ray defective weld image. By using the image enhancement processing method, the X-ray defective weld image after image enhancement processing can be more easily recognized and distinguished by the human eye.
