With the popularity of mobile and enhancement of mobile camera function, traditional digital cameras and scanner functions are gradually replaced by mobile camera. There are a lot of APP on mobile and able to scan paper documents. For photographic image processing, determining the boundaries of the document area from the mobile image is the first and important step. For the traditional document image...
According to the drawback of the traditional circle target extraction algorithm used by Hough Transform, such as computation complexity, low efficiency and etc, an new circle target extraction algorithm is proposed in this paper which can extract multiple circle targets with different radius at one time. First, the Average Absolute Difference is implemented to enhance the edge of the circle targets...
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...
