Curve tracking with a Heap&Hogg's Particle Filters [w/ code, OpenCV]

Screen Shot 2013-03-15 at 6.18.30 PM

I wanna share some code for 2D curve tracking with a particle filter, implementing the body of work of Tony Heap and David Hogg. These guys presented a relatively easy to implement method for tracking deformable curves through space and change in form using a Hierarchical Point Distribution Models (HPDM), which is another elegant way …

Checking for co-planarity of 3D points in OpenCV [w/code]

Hiya Just catching up on some bloggin, and I wanna share a snippet of OpenCV code on how to check if your (badly) triangulated 3D points came up co-planar, and therefore a botch triangulation. It's a very simplistic method, only a few lines, and it also is part of my Structure from Motion Toy Library …

Structure from Motion and 3D reconstruction on the easy in OpenCV 2.3+ [w/ code]

Hello This time I'll discuss a basic implementation of a Structure from Motion method, following the steps Hartley and Zisserman show in "The Bible" book: "Multiple View Geometry". I will show how simply their linear method can be implemented in OpenCV. I treat this as a kind of tutorial, or a toy example, of how …
