The Pan-Tilt Unit (PTTJ) and camera composed a vision system, which can be used in vision measurement. In this paper, a new calibration method for this vision system using differential GPS (global positioning system) is described. The calibration method is an efficient solution for large field of view. The proposed method has advantages in speed, convenience and pertinence. The experimental results...
A transform domain algorithm using channel selecting is proposed for visual saliency in this paper. This algorithm is able to improve the accuracy of the traditional transform domain saliency detection while preserving their advantage of fast processing speed. Based on the image signature algorithm, we select the channels by calculating the correlation values between each channel. Then, the selected...
A novel dehydration device was put forward to reduce the mist content in blast furnace gas. Aiming at the complex two-phase flow of curved-plate dehydration equipment, its capabilities were studied by changing the structures and operation parameters. The effects of all the factors on dehydration efficiency and pressure loss were also discussed. The results indicate that the optimum gas velocity is...
