Outline of Final Research Achievements

This research proposed approaches to recover the polyp shape and size from endoscope image. Using two images with known movement along Z direction can estimate the reflectance parameters of uniform diffused reflectance shading image which is converted from the original image, and can recover the absolute size of polyp.
Generating Lambertian image is also improved and observation model are considered and evaluated for one point light source and two point light source mdoel for shape recovery of polyp and it is shown that two point light source model gives better shape with estimating the absolute polyp size.
Polyp detection approach is also developed using edge information and color information, which makes likelihood map of polyp candidate region. HOG feature is taken from the polyp candidate region and machine learning approach is used to judge if the polyp candidate region is ture or false. Approach for classification of polyp with benign or malignant is also proposed.
