1、数字图像处理英文翻译（Matlab帮助信息简介）xxxxxxxxxxxxIntroductionMATLAB is a high-level technical computing language and interactive environment for algorithm development, data visualization, data analysis, and numeric computation. Using the MATLAB product, you can solve technical computing problems faster than with
2、 traditional programming languages, such as C, C+, and Fortran.You can use MATLAB in a wide range of applications, including signal and image processing, communications, control design, test and measurement, financial modeling and analysis, and computational biology. Add-on toolboxes (collections of
3、 special-purpose MATLAB functions, available separately) extend the MATLAB environment to solve particular classes of problems in these application areas.The MATLAB system consists of these main parts:Desktop Tools and Development EnvironmentThis part of MATLAB is the set of tools and facilities tha

12、ns and languages, such as C, C+, Fortran, Java, COM, and Microsoft ExcelThe basic data structure in MATLAB is the array, an ordered set of real or complex elements. This object is naturally suited to the representation of images, real-valued ordered sets of color or intensity data.MATLAB stores most
13、 images as two-dimensional arrays (i.e., matrices), in which each element of the matrix corresponds to a single pixel in the displayed image. (Pixel is derived from picture elementand usually denotes a single dot on a computer display.) For example, an image composed of 200 rows and 300 columns of d
14、ifferent colored dots would be stored in MATLAB as a 200-by-300 matrix. Some images, such as truecolor images, require a three-dimensional array, where the first plane in the third dimension represents the red pixel intensities, the second plane represents the green pixel intensities, and the third
15、plane represents the blue pixel intensities. This convention makes working with images in MATLAB similar to working with any other type of matrix data, and makes the full power of MATLAB available for image processing applications.The Image Processing Toolbox software is a collection of functions th
