Improving radiographic image contrast using multi layers of histogram equalization technique

<span id="docs-internal-guid-43432eef-7fff-9949-6deb-865191ff0740"><span>Usually, X-ray image has distortion in many parts because it is focusing on bones rather than other, However, when dentist needs to make decision analysis, he does that by using and opinions can be judged looking closely like (inflammation, infection, tooth nerve, root of the tooth…). This paper proposes new suggested technique applying multilayers histogram equalization (HE) contrast limited adaptive (CLAHE) order high X-ray, this provides very satisfied results smooth intensity which leads clear image, Python3 OpenCV.</span></span>
