OVERVIEW:


This model is concerned with the learning of motion features for dynamic scenes classification based of slow feature analysis. The model takes inputs from basic V1 features as described here IP2013. From the V1 outputs of video frames the model learns motion features based of slow feature analysis (SFA) as illustrated below and thoroughly explained in this [technical report] .

CLASSIFICATION RESULTS:


Classification on two dynamic scenes data sets generates state of the art results.
