Line segment detection is widely used in image process and recognition field. Conventional Hough Transform (CHT) is one of the popular techniques to detect lines accurately. Randomized Hough Transform (RHT) decreases the huge computation of CHT, but the random samples produce large invalid samples, so it increases the time and space complexities. Another disadvantage of RHT is that some important...
The recognition of the wheel rim is a crucial area for vehicle safety. We present a novel recognition method for the detection of wheel rim whose projective curve is an ellipse. An image preprocessing method including the Otsu algorithm to binary the gray image, removing spurious areas and region filling algorithm is introduced to segment the rim area correctly. Then the ellipse rim region is considered...
