示例：数字识别
要识别的图片：
halcon源码：
1: *读取图片
'D:/MyFile/halcon/数字识别/1.jpg')
3:
4: *图像处理
5: decompose3(Image, ImageR, ImageG, ImageB)
6: threshold (ImageG, Regions, 0, 183)
7: connection (Regions, Connection)
8:
'and', 1987.72, 7500)
10:
'Document_0-9.omc',OCRHandle)
12: do_ocr_multi_class_mlp(SelectedRegions,ImageG,OCRHandle, Class, Confidence)
