Aligning multiple images into one image?

What is a good method to align images together that may have different rotations, exposures, etc, but have the same background or other fixed reference? Adobe Photoshop can do this with its "Photomerge" feature. How can I do this programatically? Is there an Open Source application that does it? ...

Template matching algorithms

Please suggest any template matching algorithms, which are independent of size and rotation. (any source codes as examples if possible please) EDIT 1: Actually I understand how the algorithm works, we can resize template and rotate it. It is computationally expensive, but we can use image pyramids. But the real problem for me now is whe...

Whenever I use cvMatchTemplate in openCV, I get a segmentation fault. Why?

Hey guys and gals, I'm trying to do a simple template match in openCV and at the line in my code where I call cvMatchTemplate, I get a segmentation fault. I don't know if this is relevant, but i'm on a mac using x11 and i'm using opencv 2.0.0. Here is relevant code: IplImage* imgOriginal = cvLoadImage("reference.png", 0); IplImage*...

A name for a template-matching parameter

In my template-matching code I need the user to pass a floating-point parameter, which specifies whether the algorithm should concentrate only on the best matches (thus work faster) or analyse even low-probability areas (making it slower). The parameter is linear and normalized such that possible values are in range <0, 1>. It doesn't m...
