Configurable comparison threshold

[canalun]

Hi, I'm a user of argos-ci. Thank you for developing this great application :)

I'm now facing with the threshold problem (some differences of color are not detected by argos-ci.com),
and could I ask you two quick questions?

1. Is this threshold feature planned to be supported also as an option on argos-ci.com?
2. Currently, is there any workaround for color threshold problem?(now, I take and upload snapshots by @argos-ci/cli and check the result on argos-ci.com.)

Hi @canalun, sorry for the answer delay. I think we could make it configurable, for some use cases it could make sense.

Could you send me a link of a broken build so I can check and experiment with it?

Hi @gregberge , sorry for the late reply...!

Thank you for considering the idea.
Unfortunately, I've lost the URL. But I have the original two images argos compared, and is it enough to share them??(if not, please tell me!!)

The problem with these two images is that argos did not detect the difference of 2 cells at the lower left corner, that is, "red" and "yellow" of "pale" row.
Actually, the all 10 colored cells had been changed and argos detected the difference of all other 8 cells.

I compared the two images using odiff-bin with the threshold argos uses, and, of course, the result was the same. I've not tried with different threshold yet.

We have improved our algorithm to detect color changes. See #1153
