脆弱型水印算法。先用校验和算法计算图像的高7位，得到一个56位的数据，嵌入到图像中。-Fragile watermarking. The first image with the checksum algorithm to calculate the high-7, by a 56-bit data, embedded into the image.

这个例子演示了如何Matrox MIL8 OCR控件与其他 ActiveMIL控件结合使用，读取半导体晶片中图像中的序列号。在晶片上印刷的序列号，SEMI是一个标准的的字体字符串，使用SEMI M1292，包含一个校验和。-This example demonstrates how to read the serial number in an image of a semiconductor wafer, using the CharacterRecogntion control in co

数字水印参考代码，分别用checksum，lsb，patchwork等方式嵌入水印，并且附带计算信噪比和消除水印的代码-Digital watermark reference code checksum lsb in patchwork way embedded watermark and accompanying calculated signal-to-noise ratio and eliminate the watermark code
