Description: 本示例主要的功能是通过给定的一组成绩数据绘制出成绩的分布图（包括直方图和圆饼图）。这里没有用到数据库，因为是一个简单的成绩分布图，而用数据库的话在转到另一台机子上还要重新建表，对于学生信息也要涉及到录入问题，不容易实际操作，所以本示例采用了更为方便的通过手动录入数据或者是从文件（txt格式文本文档，第一个数为总人数，其余为分数，分数之间用逗号隔开）导入数据两种方式绘制出其统计图。录入的成绩可查看可修改，直方图采用了立体图模式，看起来更直观，各个分数段都有明显的分数人数标注，看起来直观形象。饼形图也同样标注了各颜色对应的分数段及人数，看起来很直观。数据录入部分与绘图部分集成在一个对话框上面，没有在单个文档中调用，减少了不必要的繁琐过程-The main feature of this example is given a set of performance data to map out the distribution of results (including histograms and pie charts). Database is not used here because the result is a simple map, but with the words in the database to another machine on the table but also to re-build, but also for the student information related to the input problem, is not easy to practice, so this example by using a more convenient data entry or manual from file (txt format text documents, the first number is the total number of rest points, scores, separated by commas) two ways to import data to map out their charts . Entry can be modified to view the results, using a three-dimensional histogram graph model, it seems more intuitive, each segment has a significant fraction of the number of marked points, it seems intuitive image. Pie charts are also marked with the color and number of segments corresponding to the score, it seems very intuitive. Data entry and some portion of the drawing i Platform: |

Description: We present a parallel implementation of a histogram-based particle filter for object tracking on smart
cameras based on SIMD processors. We specifically focus on parallel computation of the particle weights
and parallel construction of the feature histograms since these are the major bottlenecks in standard
implementations of histogram-based particle filters. The proposed algorithm can be applied with any histogram-
based feature sets—we show in detail how the parallel particle filter can employ simple color histograms
as well as more complex histograms of oriented gradients (HOG). The algorithm was successfully
implemented on an SIMD processor and performs robust object tracking at up to 30 frames per second—a
performance difficult to achieve even on a modern desktop computer. Platform: |

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: The feature vector of
an image can be derived from the histograms of its color
components and finally can set the number of bins in the color
histogram to obtain the feature vector of desired size. Thus the
grid code of an image is obtained through the quantization of the
feature vector derived from the histogram of the desired color
component of the image. In order to have similar features of the
images the grid code must be same for all Images in the grid Platform: |
