基于ENVI二次开发，利用IDL实现了:矢量文件shp的调用 roi的掩膜 NDVI,LBV和SOBEL的阈值计算 存储生成ENVI所识别的img文件 提取海面的养殖信息 二值法分割等。-Based on ENVI secondary development, the use of IDL realized: call the vector file shp roi mask NDVI, LBV and SOBEL threshold value img file storage gene

This Matlab/C code contains routines to perform level set image segmentation according to: (1) various multiphase (multiregion) formulations, including a fast scheme where the computation load grows linearly with the number of regions and,
