R1-2

R1-2 (5-March-2020)

• 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

R1-1

R1-1 (17-April-2019)

• 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

R1-0

R1-0 (14-January-2019)

• Computer Vision functions implemented:

  • Gaussian Blur
  • Thresholding
  • Laplacian Edge Detection
  • Canny Edge Detection
  • Centroid Detection
  • User Definable Function

• Additional Features added

  • Processed image file saving. (This can work in tandem with NDPluginFile)
  • Support for mono or RGB images
  • Support for 8, 16, 32, and 64 bit images
  • Flexible and modular function implementation system
  • CSS User Interface screen
  • Documentation

• Known Limitations:

  • No current support for performing operations accross multiple images. Required for several CV functions
  • Conversion between PV and ADCV_Function is convoluted and should be reworked

• Future Release Plans

  • Expand list of supported functions
    • Motion Vectors
    • Object identification
    • Image alignment
    • More...
  • Perform tests with variety of cameras
  • Performance improvements and bug fixes
  • Expand file saving to allow for capture, stream, etc
