High Speed Approximation Feature Extraction in CAD System for Colorectal Endoscopic Images with NBI Magnification

Abstract

In this study, we have proposed an improvement for feature extraction in computer-aided diagnosis (CAD) system for colorectal endoscopic images with narrow-band imaging (NBI) magnification [1]. Dense Scale-Invariant Feature Transform (D-SIFT) is used in the feature extraction [3]. It is necessary to consider a trade-off between the precision of the feature… (More)
