Parameter

  • x [pixel]: X coordinate of the lower left corner of the ROI.
  • y [pixel]: Y coordinate of the lower left corner of the ROI.
  • width [pixel]: The width of the ROI.
  • height [pixel]: The height of the ROI

Inputs

  • image_path: A path to a detector file.

Outputs

  • sum: The sum of the ROI.
  • mean: The arithmetic mean of the ROI.
  • min: The minimum intensity value of the ROI.
  • max: The maximum intensity value of the ROI.
  • std_dev: The standard deviation of the ROI.
  • max_x: The x coordinate of maximum of the ROI.
  • max_y: The y coordinate of maximum of the ROI.
