0.18.3

What's Changed

• Add runtime cache system for opencl program by @StRigaud in #447
  • Main objective is to reduce the call to clBuildProgram which, depending on OpenCL drivers, can create a significant memory leak
  • it is a short term cache with a maximum of 64 entry
  • it co-exist with the long term cache of pre-build program stored on local system

0.18.2

What's Changed

• Fix a memory leak (discussed here) caused by a buffer pointer no deleted when allocating space for buffer by @StRigaud in #443 and #444

• Side notes:
  No leak observed on Ubuntu system. valgrind report is in the clear and manual verification does not show increase of memory usage over iteration.
  Possible issue of memory bulking can be directly related to vendor implementation of OpenCL. Mainly for MacOS which does not support OpenCL anymore but instead rely on a CL2Metal convertion.

0.18.0

What's Changed

New operations by @StRigaud in #438 and #440

• Add merge_touching_labels
• Add sato_filter, a ridge detector (2d) and a tube detector (3d)
• Add hessian_gaussian_eigenvalues, same as hessian_eigenvalues but the hessian matrix is computed using a gaussian derivative instead of direct derivative which allows to introduce a scaling factor in the hessian
• Add gaussian_derivative which convole the input with a gaussian derivative of order 0, 1, or 2, where order 0 is equivalent to a gaussian_blur
• Add percentile, compute the percentil value of an image

Fixes by @StRigaud in #440

• Fix gradient_x, gradient_y, gradient_z to return the correct gradient direction, with a forward/backward approximation on the edges for better precision
• Now the eigen value of the hessian computation are return from the largest first to the smallest last

Minor change by @StRigaud in #439 and #440

• Extend execute_separable to accomodate a order parameter
• Remove warning message for statistics function call when only one of both input intensity and label is provided. This was more troublesome than informative
