In order to better handle gradients, you can also select the pixel radius that should be used to analyze adjacent pixels.

If there is an item on the underlying page that is not outlined in the output mask, then the item does not have enough color contrast according to the conformance level you selected. The output will show you a map of where the edges between colors are different enough to meet the specified contrast requirement.

To analyze local files you will need to go to your Extensions page and check "Allow access to file URLs" for this extension.
