Description: 此设计要求能够实现将医学图像进行识别的过程，包括了图像预处理、图像特征提取及分类判决三大模块。在预处理这一步中主要实现的是将彩色图像转换为灰度图像，灰度图像的二值化，直方图修正，去除干扰、噪声以及差异，边缘增强等；第二模块是图像的特征提取。由于对象的物理与几何特性差异，在影像中表现为局部区域的灰度产生明显变化，形成影像特征，而图像特征提取就是对其进行加工、整理、分析、归纳以便提取构成目标影像的特征，得到能反映图像内容区别于其他事物的本质特征；分类判决作为第三模块，则是要在第二步的基础上采用某种分类判别函数与判别规则，通过对目标特征的分析和匹配来识别目标。-this design requirements to achieve medical image identification process, including the image preprocessing, Image feature extraction and classification ruling three modules. This pretreatment step in the main achievement of the color image is converted to grayscale images, the two gray-scale image value, histogram amendment to remove interference and noise variance Edge Enhancement; the second module is the image feature extraction. Because of the physical objects with geometric characteristics difference in the images showed local area Gray significant changes, the video features, feature extraction and image is its processing, compilation, analysis, summarized in order to extract constitute the target image features can be reflected image as distinct from the other characteristics of th Platform: |

Description: Abstract—Based on the observation that low-frequency DCT
coefficients of an image are less affected by geometric processing,
we propose a new blind MPEG-2 video watermarking algorithm
robust to camcorder recording. Both the embedding and
extraction of the watermarks are done in the compressed domain.
The mean of the low-frequency DCT coefficients of the video is
temporally modulated according to the information bits. To
reduce complexity, we embed watermark in the prediction error
signals of the B-frames. Experimental results show that the
proposed scheme achieves high video quality and robustness to
camcorder recording, trans-coding, frame-rate conversion, and
geometric attacks on common test videos. Platform: |
