Abstract:

The author proposes an integer region segmentation method for type scenograph which is based on cubic uniform B-Splines and multiresolution wavelet. A math model is constructed first according to the images and a series of discrete points are gained. Then, a curve of gray changes with yawp is got by t he interpolation of cubic uniform B-Splines. A smooth curve is obtained after de-noising by multiresolution wavelet. Finally, the maximum and minimum of the first order derivate of this curve are computed, and the two edges between the target region and the background region are obtcined. Experimental r esults indicate that the speed of segmentation is very high and the effect is very good.
