This release contains some modest improvements in image combination performance. For the best performance, install the bottleneck. With bottleneck installed, median_combine is 2x faster.

Changes in this version:

  • Image combination is faster for average and sum combine, and improves for all operations if the bottleneck package is installed.
  • Pixel-wise weighting can be done for sum and average combine.
  • When filtering an ImageFileCollection by keyword value, and not explicitly using a regex search pattern (regex_match=True), escape all special characters in the keyword value for a successful search.
  • Return mask and uncertainty from combine even if input images have no mask or uncertainty.
