| Abstract(in English) | Increment in number of colorectal cancer patient increases the requirement for a more efficient diagnosis system. 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. The algorithm with a bag-of-features (BoF) representation of local features and Dense Scale-Invariant Feature Transform (D-SIFT) is used in the feature extraction. It is necessary to consider a trade-off of the precision of the feature extraction and speedup by the FPGA implementation for processing of real time full high definition (1920 x 1080) image. In this paper, we reduced the number of dimensions for feature representation in hardware implementation purpose. |
