Abstract: This paper presents two techniques, histogram equalisation (HE) and contrast limited adaptative histogram equalisation (CLAHE), for contrast enhancement of 2D magnetic resonance imaging (MRI) slices in order to reconstruct them as 3D images. These powerful techniques allow the maximum possible contrast to be established without ultimately affecting medical interpretation, based on a comparative study of three 3D images constructed by the slices: real, enhanced only by HE, and those processed by CLAHE after HE. We have experimentally demonstrated that the CLAHE technique is effective in improving contrast and reducing noise amplification especially for medical images.

Keywords: histogram equalisation; CLAHE; 3D medical image; DICOM image; image processing.
