Is there a way to increase the quality of feature matching by using (erosion, threshold, dilation/erosion etc..) prior to feature detection?

or am I missing something that I could do with the returned 1 column RANSAC mask data?

yes, use that and line it up against your point data. account for shapes and flattening. I disagree with the rest of the post. the data is certainly not useless. I see that getting data into the right shape seems to be tricky in the javascript API, but it appears to be doable.
