Image help needed

I need to put a date and time stamp on a bitmap, compress it to jpeg and measure differences between pictures (effectively motion detection). I'm not fussed if I use bitmaps or jpegs for the motion detection although presumably bitmaps are easier.

At the moment, I'm capturing said bitmap from a webcam and saving it to disk. Presumably I need to load this into some bitmap structure...?

Any help with this would be appreciated as I really haven't done any imaging code at all.

I'm writing this in a C windows application and my MFC experience is er...non-existent.

Thanks,

This will have everything you want. It's excellent, fast, has live camera interfaces and many computer vision algorithms.

That looks like that's the motion detection handled but I still need help getting the frame into a bitmap structure and doing the date and time stamp.

There doesn't seem to be a great deal of interest in my question here in the C area so I might widen it to some other topic areas...

Points increased.

As I'd mentioned in an earlier post, I still need help with the other two areas but I'll raise a separate question for each of these.

It was probably a wee bit cheeky of me to ask 3 questions in one anyway as I'm possibly less likely to get an answer to all 3 as it may require different levels of expertise.

I'm happy to raise a couple of questions for the missing bits. I got a quality answer for the other bit so I was happy to allocate all the points in this case.

Thanks,
