Abstract: For the type-1 fuzzy set’s membership function is crisp and unflexible，and it is difficult to meet many of the edge detection requires.And the traditional PalKing methods using a single threshold image enhanced don’t meet with gray-rich changes and a great deal of information，the color remote sensing image processing.A new method color remote sensing image edge detection using IT2FS is proposed.The results show that it can better detect the edge of color remote sensing images，so it is a practical and effective remote sensing of color edge detection method.

摘要： 针对一型模糊集其隶属度函数是确定的，不具有柔性，很难满足图像的多方面边缘检测要求，及传统PalKing算法采用单一阈值对图像进行增强难以满足灰度变化丰富且含大量信息的彩色遥感图像处理的要求。提出了一种新的基于区间二型模糊集的彩色遥感图像边缘检测方法。实验结果表明，它能较好地检测出彩色遥感图像边缘，因此是一种实用有效的彩色遥感图像边缘检测方法。
