Description: 近年来，随着互联网的高速发展，网上的多媒体信息也急剧增加，这些多媒体信息以图像为主。如何从浩瀚的图像数据库中快速、准确地找出所需要的图像，己成为一个备受关注的研究课题。有效地组织、管理和检索大规模的图像数据成为迫切需要解决的问题。于是基于内容的图像检索(Content-Based Image Retrieval: CBIR)作为一个崭新的研究领域出现了。
本课题拟研究、分析彩色图像红、绿、蓝三基色直方图的生成、特征提取和相似度等问题，应用图像的颜色信息—三基色直方图对图像进行检索。针对基于颜色的图像检索，本文采用应用广泛的RGB颜色空间来表示图像的颜色特征，对颜色分量进行等间隔量化并形成特征矢量并对特征矢量进行归一化处理，采用图像均匀分块的方法引入图像中色彩所处的位置信息，用距离度量函数进行图像的相似性匹配。在此基础上实现了基于三基色直方图算法的检索系统。
本文的研究和实践对于促进基于内容的图像数据库检索技术的应用具有一定的参考价值和实践意义。-With the rapid development of Internet, the multimedia information is booming. All this information is mostly images. Effective recognizing, management and searching all these images have been an emergent problem. This has led the rise of a new research and development field: Content-Based Image Retrieval (CBIR).
The topics to research, analysis color images red, green and blue color histogram generation, feature extraction and the similarity of the issues, application of the color image- trichromatic histogram of the image retrieval. Based on the color against the static image retrieval, this paper application of a wide range of RGB color space to indicate the color image features, the color components, such as spacing and quantitative characteristics of a feature vector and a normalization of vector processing, using uniform image block the introduction of the method in which the color image Location information, and distance measuring function similar to the image of the match.

Description: The following implementation steps have been made for the devised algorithm, which is based on 2D-wavelet.
1. Reading an image of either gray scale or RGB image.
2. Converting the image into grayscale if the image is RGB.
3. Decomposition of images using wavelets for the level N.
4. Selecting and assigning a wavelet for compression.
5. Generating threshold coefficients using Birge-Massart strategy.
6. Performing the image compression using wavelets.
7. Computing and displaying the results such as compressed image, retained energy and Zero coefficients.
8. Decompression the image based on the wavelet decomposition structure.
9. Plotting the reconstructed image.
10. Computing and displaying the size of original image, compressed image and decompressed image.

Description: Normalises image values to 0-1, or to desired mean and variance
Usage:
n = normalise(im)
Offsets and rescales image so that the minimum value is 0
and the maximum value is 1. Result is returned in n. If the image is
colour the image is converted to HSV and the value/intensity component
is normalised to 0-1 before being converted back to RGB.

Description: RGB,YCbCr,HSV,HSL,CIE等颜色空间转换
这个Matlab程序用于颜色空间的转换。可以在RGB, YPbPr, YCbCr, YUV, YIQ, YDbDr, JPEG-YCbCr, HSV, HSL, XYZ, CIE Lab (CIELAB), CIE Luv (CIELUV), and CIE Lch (CIELCH)等颜色空间中任意转换。-B = colorspace( dest<-src , A) converts image A from color space src to color space dest .
Example:
B = colorspace( HSV<-RGB ,A) Convert image A from RGB to HSV
C = colorspace( YCbCr<-HSV ,B) Convert HSV to YCbCr
D = colorspace( RGB<-YCbCr ,C) Convert YCbCr back to RGB

Description: The Matlab function RGB() converts a color index (whole number from 1-21), English name of a color (string), or RGB triple with whole number components in {0, 1, ..., 255} into an RGB triple with real-valued components in [0,1]. RGB() allows the user to access a set of 21 colors via their common English names. For eight of these colors that have more than one common name, the program accepts alternative names, reducing the memory burden on the user.-The Matlab function RGB() converts a color index (whole number from 1-21), English name of a color (string), or RGB triple with whole number components in {0, 1, ..., 255} into an RGB triple with real-valued components in [0,1].
