Based on a request by u/BootsMade4Walking -- add ability for CM to detect solid, well-defined logos in an image.

Potentially can use openCV (using opencv.js?) template matching, assuming the logo is provided and well-isolated. Potentially can make the detection scale/rotation agnostic.

To determine:

  • Possible to use opencv.js in CM?
  • Can use opencv.js for template matching with decent performance?

Template matching js example

Could also be used to determine if an image is cropped or not -- https://stackoverflow.com/a/60120165/1469797

Will need to integrate openCV dependency into docker and provide a path/docs for doing so on non-docker installations.
