Re-exports

• pub use opencv;

Structs

• EccMatchParameters
  Structure containing the opencv parameters needed to calculate ecc_match()
• KeyPointMatchParameters
  Structure containing the opencv parameters needed to calculate keypoint_match()

Enums

• MotionType
• StackerError

Traits

• SetMValue
  Trait for setting value in a 2d Mat Todo:There must be a better way to do this

Functions

• collect_image_files
  Returns paths to all jpg,jpeg,tif and png files in a single directory (non-recursive)
• ecc_match
  Stacks images using the OpenCV ECC alignment method. https://learnopencv.com/image-alignment-ecc-in-opencv-c-python All files will be aligned and stacked together. The result is returned as a Mat<f32>. All images will be position-matched against the first image, so the first image should, preferably, be the one with best focus.
• keypoint_match
  Stacks images using the OpenCV keypoint match alignment method. All files will be aligned and stacked together. The result is returned as a Mat<f32>. All images will be position-matched against the first image, so the first image should, preferably, be the one with best focus.
