* Replace signal-based abort handling by query-based handlingWillem Jan Palenstijn2019-08-149-44/+19
| | | | | | | | The abort handling is currently only used to process Ctrl-C from Matlab. Since Matlab R2019a, it appears that calling utIsInterruptPending() from a thread other than the main thread will crash. The previous approach of checking utIsInterruptPending() in a thread, and then signalling the running algorithm was therefore broken.

* Fix scaling for fan/strip projectorWillem Jan Palenstijn2019-03-291-8/+46
| | | | | | | | | | | | The strip model for a fan beam geometry wasn't taking pixel magnification into account. Among other things, this resulted in diagonals through rectangles being weighted the same as hor/ver lines. This commit fixes this by scaling each pixel contribution by its magnification on the detector. This is only an approximation (since the magnification isn't constant inside the pixel), but since pixels are usually small, the error is also small. Unfortunately, computing this scaling factor is relatively expensive because it introduces a square root in the inner loop.
* Flip wrong detector orientation for fan2d_stripWillem Jan Palenstijn2019-03-231-2/+2
| | | | | | There are still some remaining fan2d_strip unit test failures, with suspicious slightly too large numerical deviations around 45 degree projections.
* Some basic optimizationsWillem Jan Palenstijn2019-01-241-46/+41

* Remove largely unimplemented CProjector2D::projectPoint methodWillem Jan Palenstijn2019-01-2411-75/+1
| | | | This includes the astra_mex_projector('splat') matlab function.

* More gracefully handle config errors in geometriesWillem Jan Palenstijn2018-12-237-0/+19
|
* Read filter config for FBP from cfg.optionsWillem Jan Palenstijn2018-12-061-1/+3
| | | | | | | Since these settings are optional, they should have been in cfg.options instead of directly in cfg. The old syntax remains a fallback. This has the side-effect that the tomopy/astra interface can also supply them.
* Add minimal GPU Array interfaceWillem Jan Palenstijn2018-11-014-3/+22
| | | | | This extension (only) allows creating a CUDA 3D array, copying projection data into it, performing a BP from the array, and freeing the array.
