C#调用WITIAI模型
C#调用WITIAI模型（1）WITIAI软件训练好AI模型后，采用C#调用AI模型，得到分割分类图。
（2）halcon、opencv的接口都预留了，满足工业需求；
（3）Demo代码如下：
string ImagePath = this.textBox1.Text.ToString();
int sliceImageSize = 512;
double overRate = 0.0;
double image_threshold = 0.5;

int ImageChannel = 1;

// 初始化AI模型
string AImodelpt = @"gray_model.WITIAI";
// method1
CallAIDLL.load_module(AImodelpt, GPUindex);
CallAIDLL.PredictGrayImage(ImagePath, savepath1, sliceImageSize, overRate, image_threshold, classnum, GPUindex);
// method2 -- halcon12进行调试
