A Pseudo-HDR Method Implementation for Medical Images Enhancement New post-processing method for X-ray chest image quality enhancement

Abstract — Medical images are an important part of the diagnostic process. In many cases the accuracy of diagnosis depends on the quality of the image. The investigation and development of new medical image processing methods and systems has received great attention over the last two decades. This is due to its wide range of applications in computer-assisted methods and computer-aided methods. The proposed paper presents a new image enhancement method for X-ray images. The method uses an HDR-image creation as a technique to increase the image dynamic range. This allows after mapping an HDR-image to an LDR-image (low dynamic range image) to get a better distribution of the intensity over all pixels in the image. The result is enhancing brightness, contrast and/or sharpness of images without the appearance of visible medical artefacts
