In this paper we present a new system for generic rotation invariant 2D object detection based on circular Fourier HOG features. Our system combines the advantages of a dense voting scheme as it is used in the Holomorphic Filter framework with features based on local orientation statistics. Experiments on two different biological datasets show superior detection performance over four state-of-the-art...
Conventional current active shape model (ASM) applied to in-situ Automatic Optical Inspection (AOI) has the drawback of inability to locate position, size or orientation of detected targets. This article presents an enhanced active shape model (EASM), which evaluates both offset and orientation during component detection and positioning. The developed method is employed to inspect various electronic...
Automated techniques to optimize feature descriptor weights and select optimum feature descriptor subset are desirable as a way to enhance the performance of content based image retrieval system. In our system, all the MPEG-7 image feature descriptors including color descriptors, texture descriptors and shape descriptors are used to represent low-level image features. We use a real coded chromosome...
