This paper presents a three-frame matching method for finding the correspondences of comer points. After a two-stage corner detector is applied to each frame to extract a set of corner points as the matching primitives, candidate transition paths, which are formed by three corner points among three consecutive corner sets, are found by utilizing the smoothness constraint of motion due to inerti...

This paper designs and implements a corner detection algorithm for mining corner points on the generic shapes. The proposed corner detector detects corners by using combination of one rectangle and two ellipses (REE) with different parameter settings in their descriptions. REE combination slides along the boundary of the shape and records number of boundary points in each rectangle and ellipses...

A study is made to detect human eye from a color face image (in RGB space) using Harris corner detector and Sobel edge operator. Morphological operation like dilation and erosion are also applied to make the edge of the eyes sharp and prominent. This study is found to yield 90.47% eye detection rate which is comparable with the same obtained by other standard algorithm. Keywords-RGB color image...

This paper describes a fast face identification method with Gabor filters. Two efforts are made to achieve the acceptable processing speed: 1) we design the optimal Gabor filters with the arrangement theory that uses a few directions and layers. 2) The transformation with Gabor filters (as called Gabor transformation) is only done over the regions around the facial feature points, not the whole...

We introduce a method to detect low-level features that is prescriptive (as Canny edge-detection is) but trained by a user. The user simply chooses feature classes and points to class instances. Given a input image, we compute a probability map that indicates how likely it is to belong to each of the userdefined classes; so combining different kinds of feature detector into a single, user-train...

Rice is an important crop utilized as a staple food in many parts of the world and particularly of importance in Asia. The process to grow rice is very human labor intensive. Much of the difficult labor of rice production can be automated with intelligent and robotic platforms. We propose an intelligent agent which can use sensors to automate the process of distinguishing between rice and weeds...

This work presents a flexible feature detectors for image with reduced area, power and memory requirements, supporting a variable input resolution. It focuses on processing an image pixel by pixel and in modification of pixel neighborhoods and the transformation that can be applied to the whole image or only a partial region and identify sudden changes in an image. The proposed work is optimize...

The study presents a robust yet simple technique for the extraction of lips from human face. Harris corner detection is applied on a morphologically pre-processed human face and the location and dimension of the lips along the horizontal and vertical directions are obtained. The lip dimension thus found is compared with a predetermined dimension of the same obtained through ‘data cursor’ operat...
