* Adjust Parker weights to angular rangeWillem Jan Palenstijn2021-12-011-5/+16
| | | | | | | | This fixes a global scaling in shortscan reconstruction. Also add some debugging logs for the Parker weighting and a warning if the angular range is too small. Issue #229

* Switch cuda memhandle checks to checkCudaWillem Jan Palenstijn2021-11-171-26/+12
|
* Fix non-padded GPULink memory handling in FP3D kernelsWillem Jan Palenstijn2021-11-162-0/+11
| | | | | | | | | | This would fail silently if the output projection data object was not padded to a multiple of 32 pixels, potentially corrupting the start of projection rows. 3D GPU memory allocated by ASTRA itself is always padded by cudaMalloc3D and therefore not affected. GPULink allows bypassing this, possibly triggering this bug.

|
* Fix memory leak in CUDA 2D par_fpFerdia2020-09-111-0/+4
| | | Arrays were dynamically allocated in the function convertAndUploadAngles, but were not deallocated, resulting in a memory leak. At the end of this function I now delete [] these arrays, fixing the memory leak.

|
* Replace signal-based abort handling by query-based handlingWillem Jan Palenstijn2019-08-149-38/+6
| | | | | | | | 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.
* Add minimal GPU Array interfaceWillem Jan Palenstijn2018-11-013-8/+167
| | | | | This extension (only) allows creating a CUDA 3D array, copying projection data into it, performing a BP from the array, and freeing the array.
* Reorganize more filter size functionsWillem Jan Palenstijn2018-07-172-14/+4
