Coin recognition is one of the prime important activities for modern banking and currency processing systems in which machine vision is widely used. The technique at the heart of such systems is object recognition in a digital image. Although it has high recognition speed, the traditional method of coin recognition can not recognize the coins with similar sizes. This paper presents a method based...
We propose a hierarchical regression approach, Dirichlet-tree cascaded Hough forests (DCHF), which is based on deep learning for continuous head pose estimation in unconstrained environment, e.g., poses, illumination, occlusion, low image resolution, expressions and make-up. First, positive facial patches are learned and extracted from facial area to eliminate the influence of noise. Then, in order...
A 1-D RHT method based on symmetry point searching for ellipse detection is presented in this paper. In this method, three undetermined parameters of the candidate ellipse would be determined by two axisymmetric points and one central symmetry point. The acquisition of the group of symmetric points mentioned above could complete the ellipse detection by using only one dimension accumulation array...
