2019-08-16Improve logging of mex detection to config.logWillem Jan Palenstijn
2019-08-16Check for the mex -R2017b option in configureWillem Jan Palenstijn
Since we use mex for linking, but CXX for compiling, we also need to set a preprocessor macro to emulate the -R2017b option. Currently we use -DMATLAB_MEXCMD_RELEASE=700, but it is unclear if this is the recommended way. This is required to build with Matlab R2018a and newer.
2019-08-14Replace signal-based abort handling by query-based handlingWillem Jan Palenstijn
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.
2019-07-08Build updates for Debian 8 + CUDA10.1Willem Jan Palenstijn
Debian 7 is EOL, and CUDA 10.1 doesn't support its version of glibc. Hardcoded conda=4.6.14 for now, since 4.7.5 seems to be downloading corrupted packages when running in docker/linux-64.
2019-07-08Build updates for Win10 + VS2017 + CUDA9 + Matlab R2018bWillem Jan Palenstijn
2019-07-08Update matlab function signatureWillem Jan Palenstijn
The previous one was an undocumented educated guess.
2019-07-08Replace absolute path by relative path in builder.pyWillem Jan Palenstijn
A recent setuptools is using the full path as part of the name of the temporary build directory, which made the full temp path too long when called from conda-build in Windows.

2019-03-29Fix scaling for fan/strip projectorWillem Jan Palenstijn
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.

2019-03-23Flip wrong detector orientation for fan2d_stripWillem Jan Palenstijn
There are still some remaining fan2d_strip unit test failures, with suspicious slightly too large numerical deviations around 45 degree projections.
2019-03-23Add strip projector testsWillem Jan Palenstijn
2019-03-13Make ParStripProjector2D::getProjectionWeightsCount safer for very thin stripsWillem Jan Palenstijn
2019-03-12Fix rounding error in ParStripProjector2D::getProjectionWeightsCountWillem Jan Palenstijn
In the worst case this would lead to (nearly) empty storage for getMatrix(), resulting in (near) explicit projection matrices. (These are only used for exporting explicit sparse projection matrices to matlab/python; not for FP/BP/reconstruction.) This is a quick fix; ideally the affected code would use dynamic storage.

Read filter config for FBP from cfg.options
2018-12-06Improve detection of unused config options for filtersWillem Jan Palenstijn
The FilterSinogramId, FilterParameter and FilterD options now only get marked used if they are actually used, based on the value of FilterType.
2018-12-06Read filter config for FBP from cfg.optionsWillem Jan Palenstijn
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.
