基于像素拓展的图形分割与合成的方法研究

提出了一种新的图像分割与合成方法。对于图像的分割,提出了新的分割算法,先是手工将一些明显属于物体和明显属于背景的像素分割出来,然后创建一个小矩形区域进行像素拓展迭代,迭代到图像边界为止。对于图像的合成,采用平均法,设计了新的算法,使物体的基本颜色保持不变的同时,降低了合成图像中从源图像分割的物体与新背景的差异,并使得其饱和度、色度、强度更加自然真实。

Study on Image Segmentation and Composition Method of the Basis of Pixels Expansion

This paper presents a new segmentation and composition method. This method first separates the pixels which obviously belong to objects or background, then expands pixels and repeats this procedure until achiev.es the boundary of the image. Afterwards the cutout is focus into target image. This paper designs a new algorithm that ensures the compliance of illumination in the resultant image meanwhile preserves the color characteristic of the object. Futhermore,this method declines the comparison between the target image and the object in the original image, then makes saturation, chroma and intensity seem to be more real and natural.
