Hartley and Zisserman describe the homography calculation (or estimation) very well in their wonderful book "Multiple View Geometry in Computer Vision". However, they suggest solving the equation system by using a singular value decomposition (SVD). Another possible solution is to ...

For an assignment, I had to create a short stop-motion movie. Before starting to search for good software to aid the process of taking something like 600 photos, I decided to write a simple application by myself. Actually, I wanted ...

I continued working on my automatic panorama creation software. For now, I tried a completely different approach than bundle adjustment which provides already some interesting results (see image). Still a lot to do, though!

I started to re-implement (that is: copy) automatic panorama creation like described here. Instead of the patented SIFT however, I am using the free(?) SURF.

For now, I rely on OpenCV for almost all of the common algorithms, which appears ...

There is are three popular functions in Adobe® Photoshop® called Auto Contrast, Auto Tone and Auto Color. I have to admit that I haven't done any real research on how the underlying algorithms work, I rather played around a ...

Using OpenCV (with python) I wrote a little AR application that uses only some basic OpenCV functionality. I did this mainly to get a slight idea on the quality of my calibrated intrinsic and, of course, for the fun of ...

Homographies are really useful. Often I need to take pictures of a projection onto a surface and usually this results in some perspective distortion. Using cvFindHomography, giving 'control points', a homography can be calculated and then the image can be ...

Inverting an image in OpenCV is quite easy. No need to mess around with pointers. Actually, it can be done in a single line, with a single instruction:
