Probabilistic Volume Rendering - Feature extraction using 3D Convolutional Sparse Coding

This is the repo for feature extraction in Probabilistic Volume Rendering

Data in *.tif format have been store in folders:

data_bonsai# CT bonsai
data_kiwi # MRI kiwi
data_ldCT # Low dose CT
data_tooth # CT Tooth

Run main_generate_all.m to generate all sparse maps, response maps (3 levels with hierarchical summation at each level) Maps are stored in maps_*

Base implementation was extended from 2D version of MATLAB code from http://brendt.wohlberg.net/software/SPORCO/
