Author: Jakub Wlodek Corresponding Author: Kazimierz Gofron

Dependencies: ADCompVision requires opencv core, highgui, image processing, and image codecs, opencv_video, opencv_videoio.

Release Notes

Computer Vision functions implemented
- Video Record - allows for video recording with areaDetector
- Convert Format - Converts color format and Data type of input image.
Additional Feature changes
- Added filepath PV
- Added filepath exists PV
- Added opencv_video and opencv_videoio as library dependancies
- Added support for multithreading for certain functions
- New medm, edm, and adl screens (Courtesy of Mark Rivers)
- New rst documentation pages (Courtesy of Mark Rivers
Bug Fixes
- Edited mat2NDArray function to remove potential memory leak
- Comment + documentation updates
- Fixed bug where input pArray data would be placed into the Mat - which would result in data overwrite.
- Removed call that added unnecessary DataType attribute
- Changed doCallbacksGenericPointer toendProcessCallbacks
- Cleanup of mat2NDArray function

Computer Vision functions implemented:
- Sharpening filter
- Image subtraction
- Image statistics
- Distance between objects
Additional Feature changes
- File saving temporarily removed due to crashing issues over ssh and additional dependency
- Camera bit depth selector added to play better with higher bit images
- Image scaling corrected to account for other bit depth images
- Minor screen updates to reflect feature changes
Bugs Fixed
- Bug where invalid bit depth could cause IOC to crash
- Bug where certain PV would cause error at IOC startup
- Fixed Image passthrough to work with any bit depth
- Fixed colorspace of color images passed through
- Removed code that caused certain compiler warnings - Cleaner compile

Computer Vision functions implemented:
