-DCT domain MPEG7 Dominant Color descriptor extraction, the article at the basis of MPEG7 proposed DCT domain directly from the main color of the new method descriptor. This method saves the image in the process of decompression, which greatly enhance the compressed image for feature extraction speed and effectiveness. as part of the whole algorithm, an automatic threshold algorithm for extracting the text is also given to the description. This method can reduce the threshold to set the experience brought about by non- uncertainty, so that a more robust algorithm. Comparison Search results also shows that the algorithm is a fast and effective algorithm. The new algorithm used to compress the image database or a similar search on the Internet. Platform: |

distance model of contour fluct uation between two successive f rames in t he normalized Fourier descriptor s
domain was presented to measure t his time varying contour fluct uation feat ure of flame. The model of
contour fluct uation is effective and robust for fire recognition. To f urt her reduce fal se alarms , several
features ext racted according to color , text ure and the distance model were toget her regarded as a joint

Description: 针对不同摄像头的监控图像 ,提出了一种优化的 SIFT特征匹配的监控图像自动拼接方法。在图像整合方面 ,通过高速提取 SIFT特征描述符并进行稳定精确匹配 ,利用改进 RANS AC算法去除错配 ,从而确定待拼接图像
之间的变换参数 在图像融合方面 ,有效消除了颜色和光照差异 ,最终实现自动的无缝拼接系统。实验结果证明该方法对重叠区域小、 形变大、 有运动遮挡和噪声的监控图像有较完美的拼接效果。-Monitoring for different camera images, a SIFT feature matching optimization of monitoring image mosaic method. Image integration, through high-speed extract SIFT feature descriptor, and the stability of an exact match, an improved RANS AC algorithm to remove the mismatch, to be spliced to determine transformation parameters between the two images in image fusion, the effective elimination of the color and light differences, and ultimately seamless automated system. Experimental results show that the method of overlap is small, deformation, and have a noise monitoring exercise block and a more perfect image stitching effect. Platform: |

Description: 位图透明化显示：实现这种透明有两种方法，一种是让背景色成为白色，然后与对话框背景色进行与运算；还有一种是让背景色成为黑色，然后与对话框背景色进行或运算。这样位图的背景色就消失了。
1)创建一张大小与需要绘制图像相同的位图作为“掩码”位图；
2)将新创建的“掩码”位图存储至掩码位图的设备描述表中；
3)把位图设备描述表的背景设置成“透明色”，即不需要显示的颜色；
4)复制粘贴位图到“掩码”位图的设备描述表中，这个时候“掩码”位图设备描述表中存放的位图与位图设备描述表中的位图一样；
5)把需要透明绘制的位图与对话框绘图相应区域的背景进行逻辑异或操作绘制到对话框上；
6)把“掩码”位图与这个时候对话框相应区域的背景进行逻辑与的操作；
7)最后一步重复步骤5的操作，把需要透明绘制的位图与对话框绘图相应区域的背景进行逻辑异或操作绘制到对话框上 -Transparent bitmap display: 1) to create a size with the need to draw the images with the same bitmap as the mask bitmap 2) the newly created " mask" bitmaps stored in the mask bitmap device description table 3) the background of the bitmap device context is set to " transparent color" that does not require the display of color 4) copy and paste the bitmap to mask bitmap device context, this time the mask bitmap device descriptor table stored in a bitmap and a bitmap device description table in the bitmap 5) the need to draw transparent bitmap dialog box, drawing the corresponding region of the background drawn to the dialog box on the logical XOR operation 6) " mask" bitmap dialog box, the corresponding region of the background this time, the logic and operation 7) The final step Repeat step 5 of the operation, the need to draw transparent bitmap dialog box, drawing the corresponding region of the background logical XOR operation to draw on the dialo 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: |
