Description: DCT域中MPEG7主色描述符的提取,该文在MPEG7的基础上提出了DCT域内直接提取主色描述符的新方法.这种方法节省了
对图像的解压缩的过程，因而大大的提高了对于压缩图像进行特征提取的速度和效果.作为整个算法的一部
分，一种自动阂值提取的算法也在该文中给予了描述.这种方法可以减少因人为设定经验闭值而带来的不确
定性，使算法更具鲁棒性.对比检索试验结果也说明本算法是一个高速有效的算法.新算法主要用于压缩图
像库或互联网上的相似检索.
-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: |
