A curve fitting method based on automatically extracting subsection points is proposed to fit the wheel tread profile accurately. Firstly, the subsection points are determined by segmenting discrete points of wheel tread profile based on given errors and threshold. Secondly, the segmentation interval is determined with the respective segment point as the center, and the least squares curve fitting...
We provide a vision-related image deformation method based on Moving Least Squares (MLS) and visual saliency map. As the improvement of image deformation using MLS, we propose a new weight function to improve the MLS image deformation. A visual saliency-related deformation weight definition is proposed to ensure deformations are more easily to kept local shape on high visual saliency region and changed...
Although texture mapping is a common technique for adding apparent surface detail to 3-D objects, it lacks the capability to represent the bumpy detail and the motion parallax effect. In this paper, we propose normal vector shift, a simple rendering method to motion parallax effects on a surface with small detail. This method can be enhanced the quality of the rendering result with graphics hardware.
