Nowadays, Hough transform is always adopted to detect the seam-line of mosaic image. But the calculation is big, so the seam-line detection speed is affected obviously. In order to overcome this problem, a new detection method based on radon transform is proposed in the paper. First, a binary image is generated by edge detection technique, after the mosaic image has been smoothed based on mathematical morphology. Second, Radon transform is used to the binary image, and the extreme coordinates of the Radon transform result are determined. Finally, the seam-line location in mosaic image is determined by using the extreme coordinates. The theoretical analysis and experiment results show that the proposed method has very good detection performance.
