In response to image irregular movement caused by video cameras, a new algorithm of electronic Image Stability is proposed based on block matching. On this basis, the new three-step search algorithm has made the effective improvement to three step search method. The new three-step search algorithm solves the quivering problem in horizontal and vertical directions of images made by video cameras.
Single-sensor digital cameras capture images by covering the sensor surface with a color filter array (CFA) such that only one color sample is taken at the location of each pixel. To render a full-color image, color CFA interpolation or demosaicing using neighboring samples as a very important part of video/image processing, is required to estimate values of the other colors at each pixel. However,...
Three dimensional reconstruction technique based on machine vision is applied more and more widely. The calibration technique for vision system is one of important term. There are many calibration methods available. The homography is introduced in the paper in order to adopt a simple and convenient method for calibration and computation of line-structured light vision system. Its calibration principle...
Accurate and low-cost sensor localization is a critical requirement for the deployment of wireless sensor networks in a wide variety of applications. This paper presents a new method for the localization of a wireless sensor network (WSN) by means of collaboration with a robot, using both Monte Carlo and Kalman filtering techniques. The proposed methods are demonstrated in a laboratory environment...
This paper introduces an electronic image-stabilizing system via gyro. It adopts the high-precise MEMS gyro to estimate the motion vector. And then by using digital image process technique, compensation of jittering image sequence can be realized. It is testified by ship-borne reconnaissance system that this system can really produce high image stabilizing precision, present excellent real time processing...
The simulation of large crowds of characters is important in many fields of virtual reality, as they can increase the credibility of the virtual environments. Rendering large crowd of characters requires a great mount of computational power. To increase the efficiency for this render, we propose a GPU-based crowd rendering method. We present a novel hybrid rendering method using geometric representation...
