In this paper, we propose an algorithm to track welding line of TiG welding in welding pipe or tube. The proposed algorithm consists of detecting edge, binarization, segmenting target area, locating welding torch and locating welding line. Firstly, we use prewitt operator to form the edge of image which is acquired from industrial camera. Secondly, we achieve the binary image by using maximal variance...
It is important to extract ROI (Region of Interest) based on vision image processing in intelligent transportation system. A simple and novel approach is proposed to extract the RIO in transportation scene images. Firstly, a simple method is used to preprocess the input images; Secondly, interest pixels extraction function is defined to detect all the interest pixels from scene image using adaptive...
