Clustering analysis on images

User 2920 | 12/29/2015, 6:53:21 AM

I have a large set of documents that I need to index however the the documents of interest are a small proportion of the entire package my classifier needs to scan and identify. To get an idea of the optimum number of classes and how best to merge documents in a class I wanted to run an unsupervised clustering analysis. Does graph lab create allows DB scan on image data or i need to format the pixel data. I couldn't find any tutorial on clustering analysis on images.

You can try DB scan using features obtained by deep feature extraction. Deep feature extraction will definitely work better than raw pixels.
