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。工具箱还支持读取 RAW 文件格式。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.

处理 RAW 文件

处理 DICOM 和其他医疗文件

DICOM Support in Image Processing Toolbox

The Digital Imaging and Communications in Medicine (DICOM) Standard facilitates access to image data and files across medical imaging equipment.

Mayo Analyze 7.5 Files

Analyze 7.5 is a file format, developed by the Mayo Clinic, for storing MRI data.

Interfile Files

Interfile is a file format that was developed for the exchange of nuclear medicine image data.
