I think Washington is going to be a huge reach for you and probably not obtainable. Your upward trend in grades helps a lot. A school like Michigan is probably a more obtainable reach - they have a lot of imaging people though, so I'd stress your interest in that. I could see you getting into a few of those schools, but honestly, I could also see any or all of them rejecting you because of your GPA - and your research experience is good but won't make you stand out in a way that makes up for that.
My recommendation would be to nix Washington from your list and add a few schools slightly lower in the rankings as safer options. I would also consider if you could get a funded master's at any of these schools - if you can continue your trend of grades by doing awesome at a MS program, maybe getting a paper published, I could see that improving your results immensely.
