Overview

This code uses Recurrence Quantification Analysis (RQA) features for the task of Scene Classification. These features are computed over a thresholded similarity matrix computed from windows of MFCC features. Added to traditional MFCC statistics, they improve accuracy when using a standard SVM classifier.
