sobeledge
- sobel算法的源码,应用2个3x3的掩模中心像素（mask）检测图像的边缘。一个是检测水平边沿的 ；另一个是检测垂直平边沿的。可以自己测试和修改参数，从而得到最佳的算法值。

- 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
grayscale
- 灰階(gray-scale)圖像處理(60*60 pixel)controller控制各個程式的地址以及開關，input_mem將資料讀進記憶體，grayscale將讀取資料像素的亮度以數值來表示，將24bit的 像素化成四個8bit的值輸出。接著進入sobel，在此將前面的四個值乘上1或-1個別的相加，得出新的四個值，輸入進shiftcase進行threshold的判斷，大於threshold則表現出白色(255)，小於threshold則表現出黑色(0)，最後將結果存入記憶體out_mem。
