摘　　要： 根据JPEG压缩保护图像细节和在绿色分量上嵌入水印更能抵抗一般的保护内容的图像处理这一事实,提出一种用于彩色植物病理图像认证的小波域半脆弱水印方案.实验结果表明,该方案篡改定位准确,嵌入水印容量大,有很好的抗JPEG压缩性能,同时很好的保护了用于病害识别与诊断的颜色、纹理及图像细节特征等重要信息. A wavelet domain semi-fragile watermarking scheme for color plant-disease image authentication was presented based on the facts that image detail was protected in JPEG compression and embedding watermark in green component was more robust against content-protection image processing. The experimental results showed that the proposed scheme had the advantages such as exactly locating for malicious tampering, big embedding capability, good robustness to JPEG compression, and good protection to key characteristics used for disease recognition and diagnosis such as color, texture, and image detail.
