Summary:
When Lambertian image is assumed to recover the 3-D shape from endoscope image under the assumption of point light source and perspective projection, the image is generally converted to Lambertian image a priori in general. The aim of this paper is to reduce of this calculation cost and to improve the accuracy of results by equalization of reflectance using brightness value V and classification of the hue H. Both of H and V are obtained by HSV conversion from the original RGB image. The effectiveness of the proposed method was evaluated through the experiments using simulation image and actual endoscope image.
