Fast Image Blending and Deghosting for Panoramic Video
Chen-Hong Yuan, Jeng‐Shyang Pan, Ming‐Hwa Sheu, Tzu-Hsiung Chen · 2013
The technology of panoramic image construction is widely used in many conditions. As the increasingly demand of monitoring system application, the attribute of real-time is more important during the panoramic construction. This paper describes a method of fast building panoramic video and output frames in real-time. SURF algorithm is employed to extract features and a new method is developed to eliminate matching mistakes in this work. As traditional transform method use only one homography matrix, the stitch error in detail is obvious. In this paper the modified dual-homography is proposed to improve the stitch performance. Ghosting effect is a universal problem in image stitching and difficult to avoid. This topic use image subtraction and smooth transition blending method to avoid ghost. Since this topic skips the seam finding process, so the time consumption is low and the method can achieve real-time requirement.
