Sliding shape 14 ECCV

[FengLoveBella]

Hi shurans,
I found there was another paper about sliding shape, sliding shape(2014ECCV), there is a section about feature visualization. Can you give me some detail about your 4 features(point density,3D normal, TSDF, 3D shape),what is the physical or geometric meaning?
Thank u very much.

Here you can find more information about that paper: http://slidingshapes.cs.princeton.edu/
And there is a stand alone code to compute 3D feature from one depth map that can help you understand the feature.

@shurans thanks shurans, I have already found this useful information about this paper, I have still have a question, in this paper, you gave a codebook, 50 cluster centers obtained by k-means, the input to k-means is your 500 NYU training datas, and using the algorithm presented 'fast approximate nearest neighbors' to obtain your 50 cluster centers? Did I get it? Thank you very much!!
