4693 此外，从理论上分析了所提算法中参数的选择问题。 In addition, the parameter selection of the proposed algorithm was analyzed theoretically.
4694 仿真实验表明，所提算法比已有的特征值检测算法具有更好的检测性能。 Simulation results show that the proposed algorithm has better detec-tion ability than the existing eigenvalue detection algorithm.
4695 针对图像在网络传输中的隐私信息泄露问题，提出了一种基于二维码和可逆可视水印的图像隐私保护方案。 With the privacy leakage problem of image delivery in networks, an image privacy preservation scheme basedon QR code and reversible visible watermarking was proposed.
4696 为了保护图像拍摄时间、拍摄地点和详细描述等隐私信息，首先将这类隐私信息加密后存储在云平台，并生成能够链接到加密隐私信息的统一资源定位符。 In order to preserve the privacy information including shooting time, shooting location and detailed description, the encrypted privacy information was stored in cloud plat-forms and corresponding universal resource locator was generated firstly.
4697 该方案将统一资源定位符编码成二维码，并将该二维码作为可视水印可逆地嵌入图像中，实现对隐私信息的访问权限控制。 Secondly, the universal resource locator wasencoded as the QR code and it was embedded into the cover image using reversible visible watermarking. Therefore, the access control for privacy information could be achieved.
4698 在该方案中，使用视觉感知模型选择适合的水印嵌入参数，以平衡水印的可视性和载密图像的视觉质量。 The visual perceptual model was utilized to select adaptive wa-termark embedding parameters to balance watermark visibility and marked image quality.
4699 实验结果表明，该方案能够保证载密图像具有良好的视觉质量，同时不影响二维码的正确识别和解码。 Experimental results demon-strate that the good visual quality of marked images can be obtained and the embedded QR code can be correctly decoded.
4700 使用所提方案在保障图像传输质量的同时，也降低了隐私泄露的风险。 The proposed scheme can guarantee marked image quality and reduce the risk of private information leakage.
4701 针对 AFL 边覆盖不全、未充分利用边覆盖信息和有效字节信息的问题，提出了改进方法。 Aiming at the problems of incomplete edge coverage, insufficient uses of edge coverage information and validbytes information in AFL (American fuzz lop), a novel method was proposed.
4702 首先，设计了新的种子选择算法，在一轮循环中可完全覆盖所有已发现的边； Firstly, a new seed selection algorithm was in-troduced, which could completely cover all edges discovered in one cycle.
