I have referred to Stage I.D of this tutorial. Hope this helps.
When the features have scale and orientation assigned (e.g. SIFT features have these properties), you can compute similarity transform between each ...
I've never actually done Panorama Stitching, but I was talking to people who were, and I was involved in a project where we had to estimate the homography for fine localization for visual navigation, so here it goes.
Rough outline of the approach using RANSAC (you can read more of the approach in this Master thesis, page 12,13 - ...
From a simple Google search...
Lets assume your camera axis has polar and azimuthal angles and you want to align your frames only regarding the azimuthal angle and set the polar angle free.
First you have to find the geometric transform between sequential frames of your video, then by multiplying these sequential geometric transforms between your reference frame and the current frame you ...
