How can we make a single image from different images?

I have different images taken from a video.
Suppose i have 10 images with me and in the second image there will be a part of the first image and similarly in an image there will be the contents of the previous image.

So how can I combine all these images to a bigger image[ like image taken in landscape mode in a digital camera]

My ultimate aim is to make a map with all the images

Please Help!!

Show us the images somewhere (like http://drop.io).

The method could be as simple as subtraction or could require very complicated correlation routines; it all depends on you images.

Photoshop and lots of other software can make panoramic photos from a series of photos (frames). If you want to do it yourself, then you'll have to look into the algorithms for determining where they overlap. It's not trivial since you may have some scaling differences and distortion at the edges of the images where they overlap. Plus you can't just copy and paste or you'll have weird edge artifacts - you'll need to have jagged overlap boundaries and "feather" or fade in the overlap so it's not so abrupt looking. I suppose you could use something similar to seam carving (http://www.youtube.com/results?search_query=seam+carving&aq=f) to find the boundaries, but I really don't know how they do it.

some of the images are upoaded to the following link
please ignore the black portion in the centre part of each photo as it came from the demo version software i used to convert the video to picture
