Abnormal object detection and discrimisnation is a critical research area for vision-based surveillance systems. This paper proposes a novel algorithm for the detection and discrimination of abnormal objects, such as abandoned and stolen objects. The proposed algorithm consists of three stages and three different filters. The three stages cooperate with each other using the feedforward model to enhance...
This paper introduces a novel pre-locating algorithm for rapid logo detection in unconstrained color images. This work is distinguished by two major contributions. The first is a new method of representation for logo called “spatial connected component descriptor” (SCCD) containing connected component (CC) prediction model and effective-CC pixel distribution histogram. The former represents combinations...
The biometrics identification technology based on vein pattern has being developed rapidly in recent years. However, the vein image acquired by near-infrared (NIR) imaging device has low contrast and usually has a mount of noise which make an effective image segmentation be a great challenge. Thresholding is a popular vein image segmentation method, which is easy to calculate and can shorten the recognition...
The algorithm for image edge detection based on phase information is getting more and more application in image feature detection. After verifying the importance and stability of phase information in image processing, the importance of phase information and the application in feature detection are discussed, and then, phase congruency function is studied on. With analysing the relation between phase...
A new method for measuring cable insulation layer parameters and its principle are presented. In order to facilitate the research of testing and measuring cable insulation layer parameters, the system based on computer vision is designed using Visual C++. After the amplification coefficient of microscope is calibrated, image is captured by CCD camera. Then, for the sake of better detecting the image...
The issue is mainly directed against the research of testing and measuring the thickness and diameter of cable insulation layer. The paper starts with designing a cable insulation parameters measurement system based on digital image processing in which image denoising and edge detection are completed through software programming. Total variant denoising method is used in the process of image denoising...
