Answer 1

With respect to your first option: The Matlab Coder now supports many image processing functions (partly via system objects) to automatically generate C-code of your algorithm, which is basically platform independent and needs no runtime environment. From my experience this code is about a factor 2..3 slower than "hand-coded" OpenCV (strongly depends on your algorithm and cpu). The main drawback is, you need a Matlab Coder license ($$$).
