ITK Release 4/Microscopy/File Formats

Overview

Microscopy applications use a very specific set of file formats, many of which are not supported in ITK by the version 3.20.

Among the initiatives of ITKv4, we are improving the support for file formats that are relevant to the microscopy image analysis community.

Bio-Formats

The Bio-Formats library is probably the most complete collection of readers and writers for image file formats of interest to the microscopy community.

The Bio-Formats library is implemented in Java and it is distributed under the GPL license. ITKv4 now carries adaptors to this library that can be enabled at CMake configuration time.

JPEG2000

• ITKv4 has adopted a branch of the openjpeg repository (from the v2 branch)
• There are failing tests in some of the Windows builds, that still have to be addressed.
• Now that openjpeg is preparing to do a new release of the v2 branch, we should look at updating the version in ITK again.
