基于DCT编码图像分割算法研究

摘要

The traditional image segmentation algorithm is not satisfied for its interactive computation and its weak real time performance. A new method was proposed based on DCT codeu image segmentation algorithm. The algorithm is an improved interactive fast segmentation algorithm, DC coefficients and AC coefficients extracted texture features,combined with adaptive regularization parameter structure into an energy function. The test results show that this algorithm not only split a good effect,but also greatly improved the efficiency of the algorithm.%针对传统图像分割算法存在的计算量大和实时性能不佳等问题提出了基于DCT编码图像分割算法。该算法的是一种改进的交互式快速分割算法，通过DC系数与AC系数提取出纹理特征，结合自适应的正则化参数构造成一个能量函数。测试结果表明此算法不但分割效果很好，而且算法效率也大大提高。
