-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.

Description: 状是含有高层语义信息的视觉特征，在基于内容的图像检索及图像识别中具有重要的应用价值。有很多种描述子可以描述图像的形状特征，傅立叶描述子可以把二维的图像轮廓信息简化成一维问题进行处理，应用非常广泛。然而自然图像的形状特征通常是杂乱的，有噪声的，提出了一种图像预处理方法，得到净化的形状图像，通过实验研究傅立叶描述子算法提取形状特征的效果。-Abstract Shape is a visual feature which contains intrinsic high-level semantics, and has a great application value in CBIR(Content-Based Image Retrieval) and IR(Image Recognition). There are many descriptors for shape feature. Fourier descriptor predigests 2-demensional image information to 1-demensional signal and be used widely. In fact, the shape of natural image is often messy and noisy. So, this paper proposes a preprocessing method which can clean the noisy shape image, and then researches and analyses the shape feature extraction with Fourier descriptor method with an experiment.

Description: 本实验要求编写课本上11.2.3节描述的傅立叶描绘方法。用实验09-02中的程序提取图12.18两幅图的边界，然后对每个边界选取256个描述点。选择的这256个点是在空间上尽可能均匀的点。获取每个图的傅立叶描绘子，确保每个图中的起始点是近似相同的点。分别用16，32，64和128个描绘系数逼近边界，并画出每一个结果。-Prepared at the request of the experimental section 11.2.3 textbook depicts Fourier method described. 09-02 with the experimental procedures in Figure 2 Extraction of Figure 12.18 the border, and then select the border of each description of 256 points. This choice is the 256 as far as possible in the space of the points evenly. Access to each of the Fourier descriptor map to ensure that each figure is the approximate starting point for the same point. 16,32,64, respectively, and coefficient of close to 128 described the border, and the results of each draw.
