Feature Extraction From Intensity Images
C. L. Huang, Julius Τ. Tou · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1987
This paper presents a new method to obtain the features from intensity images by making use of an improved Hough Transform. Through image preprocessing, the intensity image can be converted to a boundary image. A new approach is proposed to find the linear and elliptical features embedded in the boundary image on which there are discon-nectivities and the distortion that are caused either by occlusion or by noise. The Hough transform method is improved to recognize those features with less computation effort and more accuracy.
