Image Processing Toolbox 4.1 Release Notes


New Features

This section introduces the new features and enhancements added in the Image Processing Toolbox 4.1 since Version 4.0 (which was released as a Web-download release after Release 13).

Reading and Writing Data with JPEG Lossless Compression

The toolbox now supports reading and writing data that has been compressed using JPEG lossless compression. With lossless compression, you can recover the original image from its compressed form. Lossless compression, however, achieves lower compression ratios than its counterpart, lossy compression.

Using either the imread function or the dicomread function, you can read data that has been compressed using JPEG lossless compression.

Using either the imwrite or the dicomwrite function, you can write data to a JPEG file using lossless compression. For the imwrite function, you specify the Mode parameter with the 'lossless' value. For the dicomwrite function, you specify the CompressionMode parameter with the 'JPEG lossless' value.
