原载体图像.实验表明,该算法具有较强的鲁棒性和良好的不可感知性,可有效低抗剪切、加噪、锐化等常见的图像攻击.-Out of a neighbor-based interpolation of the adaptive sampling method detection singular color image watermarking algorithm. Neighbor interpolation algorithm uses the sampling method, in accordance with the size of vector images, adaptive binary watermark image of size, by scrambling ArnoM after pretreatment embedded into the color vector image of blue high-frequency component coefficient Dcr detected when do not need the original vector image. The experiments show that the algorithm has strong robustness and good can not be perceived, effectively low-shear, noise, sharpening and other common image attacks. Platform: |

Description: When designing software for processing images for the characters, each character is converted into a matrix M (7,5)-valued binary (black =1 and white = 0)
Due to memory problems we wanted to compress the vector M.
The program reads from the conversion matrix M and the matrix M in a vector V, and compression of vector V -> C
and end is the display of vector C -When designing software for processing images for the characters, each character is converted into a matrix M (7,5)-valued binary (black =1 and white = 0)

Description: - Color provide an important clue for extracting the new color LBP histogram features for face recognition using Local Binary Pattern technique. To reduce redundancy RGB color space converted to YCbCr color space. The Local Binary Pattern is a non parametric operator which describes the local spatial structure, of an image into the global features. The face features based on Local Binary pattern has proven to be highly discriminative, which is invariance to monotonic gray level changes and computational efficiency that make it suitable for demanding image analysis task. The Local Binary Pattern features distribution are extracted and generated into a spatially enhanced feature vector to be used as a face descriptor. Color information can become significant for improving face recognition performance of CAS PEAL database, Platform: |

Description: 局部二进制模式,LBP,是已被用于纹理特征的一个
分类。在本文中,提出了一种基于使用这些功能的方法
检测缺陷图案的面料。在培训阶段,在第一个步骤LBP算子是
施加到无缺陷织物样品,逐个象素和参考的所有的行(列)
特征矢量的计算。那么这个图像被分为Windows和LBP算子是
应用这些窗口的每一行(列)。根据与参考比较
特征向量一个合适的阈值,无缺陷的窗户被发现。在检测阶段中,一个
测试图像被划分成的窗户,并使用阈值时,有缺陷的窗口可以
检测到。该方法简单,灰度不变。由于其简单性,
线上实现是可能的。-Local Binary Patterns, LBP, is one of the features which has been used for texture
classification. In this paper, a method based on using these features is proposed for
detecting defects in patterned fabrics. In the training stage, at first step LBP operator is
applied to all rows (columns) of a defect free fabric sample, pixel by pixel, and the reference
feature vector is computed. Then this image is divided into windows and LBP operator is
applied to each row (column) of these windows. Based on comparison with the reference
feature vector a suitable threshold for defect free windows is found. In the detection stage, a
test image is divided into windows and using the threshold, defective windows can be
detected. The proposed method is simple and gray scale invariant. Because of its simplicity,
online implementation is possible as well. Platform: |
