TXI: Texture and Color Enhancement Imaging for Endoscopic Image Enhancement [PDF]
Journal of Healthcare Engineering, 2021 Recognition of lesions with subtle morphological and/or color changes during white light imaging (WLI) endoscopy remains a challenge. Often the endoscopic image suffers from nonuniform illumination across the image due to curvature in the lumen and the direction of the illumination light of the endoscope.
