摘要:随着计算机的发展，数字图像处理技术也受到了越来越广泛的关注，其本身有着不可估量的优势和前景，数字图像处理正与当今社会的各个方面紧紧相连，密不可分。图像任意区域的拾取是图像处理的重要内容之一，通过拾取感兴趣目标区域图像能够克服传统以整个图像作为处理区域的缺点，达到减少数据量，减少像素非相关性，提高处理精度的目的。本文在分析经典有序边表填充算法的基础上，提出一种基于B样条的有序边表填充算法，详细分析了该算法的流程、实现步骤并给出了具体实现案例。文中对BMP文件结构、边填充算法、B样条进行了一定的分析，从而提出新的算法思想。通过程序试验加载BMP图样并进行区域拾取，试验结果分析表明基于B样条边填充算法有效，具有可行性。

Abstract:With the development of the computer, digital image processing technology also received more and more extensive attention. It has immeasurable advantages and prospect. Digital image processing is working with today's various aspects of society closely linked. Pick up any area of image is one of the important contents of image processing, through picking up the interested area can overcome the shortcomings of traditional image processing that the whole image as target area, to reduce data quantity, reduce the correlation of pixel , improve processing precision . Based on the analysis of the classic orderly side table filling algorithm, a new orderly side table filling algorithm based on b-spline is proposed. This paper shows a detailed analysis of the algorithm process, implementation steps and gives a concrete realization cases. With the analysis of BMP file structure, side filling algorithm, b-spline conducted, a new algorithm was proposed. Through the program test BMP pattern and regional to pick up, the results show that the side filling algorithm which based on b-spline is effective and feasible.
