In final approach of rendezvous between a space robot and a non-cooperative target, due to the light and the folds of heat cladding materials on the target surface, the edge of target cannot be accurately extracted by classic Canny algorithm and we are unable to complete measurement of relative position and attitude. To solve this problem, the measurement method of relative position and attitude between...
Traffic video surveillance cameras are widely used in China today. However, the resolution of the output video is very low and it is difficult to recognize the license number of the vehicles that broke traffic regulations. The Super-resolution image reconstruction techniques thus can be used to solve this problem. In this paper, we examine several important superresolution algorithms and developed...
In the production of copper electrolytic, short circuit frequently takes place between anode and cathode, the heat loss from which will result the reducing for the production of copper. To solve this problem, this paper presents a high-temperature electrode faulted diagnosis method base on the new-type integrated filtering of thermal infrared images and the division and location processing. Short...
To extract a more reliable cavity boundary from ultrasound images, a three step algorithm is presented in this paper. In the first step, we transform the ultrasound image into an appropriate feature space, in which the spatial distribution of the cavity inside the ultrasound images is represented. Next, morphological filtering is used to get an initial contour of the cavity. The initial contour is...
