基于文件读写图像数据

基于文件读写图像数据，获取图像文件的内容信息

Image Processing Toolbox™ 使您能够读取和写入许多常见文件格式的图像文件，包括 BMP、GIF、JPEG、PNG 和 TIFF。该工具箱支持读取和写入医疗文件格式，包括 DICOM、NifTI 和 Analyze 7.5。您还可以处理特殊文件格式的图像，包括 NITF、DPX 和 Interfile。

Image Types in the Toolbox

Image types determine how MATLAB^® interprets data matrix elements as pixel intensity values. The toolbox supports many image types including binary, grayscale, truecolor, multispectral, and label images.
