本文提出一种首先进行平滑滤波，然后检测模糊边缘的方法来进行复杂景物图像边缘检测。
In the paper, a way of smooth filtering first, then detect edge using fuzzy sets in complex scene image is provided.
景物边缘信息是进行图象分析和识别的重要属性，如何有效地从噪声图象中提取边缘是这些领域中的难点。
Edge is an important attribute for image analysis and recognition, but it is difficult to effectively extract edge from noisy image in the domain.
实验结果表明，改进后的颜色估计模型在图像边缘附近颜色相差较大的自然景物提取中有较好表现。
The improved color estimate model has better behavior in the natural image matting for the image which the edge color is very different.
