TIGRE Versions Save

Features

In MATLAB code:

• Arbitrary axis of rotation: the rotation is not anymore limited to Z.
• AwASD_POCS: TV algorithm
• PCSD: TV algorithm
• AwPCSD: TV algorithm
• Re-structuring of error checking: more robust TIGRE
• Minor speed inprovements
• Many bug fixes

This is a major release:

Features:

• Python TIGRE v0.1. A version on Python (currently only Linux is supported) - As fast (or faster) than MATLAB - All algorithms but TV based ones are included - Cone and Parallel beam - Fully compatible with Tomopy

• Added Nesterov update to SIRT/SART/OS-SART, improving vastly convergence rates.

• Ax and Atb have big speedup in memory handling, as significant improvement in big images.

• Non-Negativity constrain option added to algorithms

• FBP added for parallel beam

• Compilation code is more flexible

• several bug fixes

OSC-TV was wrongly named and referenced.

The name of the algorithm has been changed to OS-ASD-POCS

Small bug fixes

Small speedup of the projection operator

Small fix that makes CGLS work better, as a small weight was wrongly applied.

A new stable version of TIGRE is out!

Changelog:

• FDK has now Parker weights.
• Detector geometry now has Roll/Pitch/Yaw rotations, with a new demo 17.
• Centre of Rotation correction can now be applied per angle
• Minor Bug Fixes and improvements
