Data acquisition and storage is an important step in the process in building GIS system. In the process of building a database, using the method of intelligent automatic vectorization is of great significance for reducing the workload of building a database and improving working efficiency. This paper presents a method of point pattern recognition based on interactive approach, that is to say, the...
In fingerprint feature extraction, it is perceived that pixel-level image rotation transformation is a lossless transformation process. In this paper, investigation has been conducted on analyzing the underlying mechanisms of fingerprint image rotation processing and potential effect on the major features, mainly minutiae and singular point, of the rotation transformed fingerprint. Qualitative and...
Now-a-days, surveillance cameras have been widely deployed in various security applications. In many surveillance applications, the background changes very slowly and the foreground objects occupy only a relatively small portion of a video frame. In these type of applications, an efficient solution for transmissions over bandwidth-limited networks is to send only the foreground objects for every frame...
Wood defects influence on wood production quality. Image Processing of wood defects is important for wood defects detection. X-ray was adopted as a measure method for wood nondestructive testing. Because it not only can detect wood seeming defects, but also can detect inner defects. The collected images with defects were done median filter processing and edge detection so that the position, size and...
In this paper we propose a novel method to detect and record various posture-based and movement-based events of interest in a typical elderly monitoring application in a home surveillance scenario. Posture-based events include standing, sitting, bending/squatting, side lying and lying toward the camera. While movement-based events include running, jumping, active and inactive events. For posture classification,...
