Re: March 21 - Day FOUR: When to Use FPGAs to Accelerate Embedded Vision Applications

As OpenCV uses C code internally and also has a C interface, has anyone heard of or ever tryed out C-to-HDL converters? (I know there would still a lot of work to do with the generated HDL code ;) )

You already show your maturity by pointing out that there's still a lot of work to do with the generated HDL.  Since software (instruction-centric) is different than hardware (data flow centric), the C-to-gates process is obtuse and buggy at best.  At worst, it's just totally impossible.  (There's no straightforward way to implement a linked list or a heap or a dynamic array in hardware.)  

There are some high-level tools that can help.  Being a National Instruments employee, I've used and really like LabVIEW FPGA, but then again I'm biased, so take that for what it's worth.
