Gradient Field HOG Update 

Every so often we get contacted about algorithms our group (lead by Dr. John Collomosse) have implemented. Due to a recent request I have updated the files downloadable for the implementation of Gradient Field HOG, little changes to make it easier. Included additionally is the Windows dependent libraries to make it a little to compile and run the code.

Rotor Style Skeleton Browser 

A while ago I found a paper from a research project called MediaMill. They presented a technique for viewing different facets of video content in a windmill fashion. Recently I was exploring how we could visualise skeletons and thought would give the technique a try, here is a screenshot of a basic approach:

In this example each joint (of which there are 10) is represented on a “blade”. This very simple example visualise joint variation a better approach would to measure the distance between the body and variations on a specific joint but hey was just a sample.

Skeletons from Sketches of Dancing Poses paper for VL/HCC 2012 Demo 

I have put together a quick demo for the upcoming conference. Sadly I wont be there to present the work but the main author Manuel J. Fonseca from IST is going to be there.

Give it a play and let us know what you think. This is a heuristic approach to parsing of sketched postures into a skeleton.
