The repo contains a library with all the functions to perform spatial saliency detection. The theoretical basis for this implementation is the following paper:
Itti, Laurent & Koch, Christof & Niebur, Ernst. (1998). A Model of Saliency-based Visual Attention for Rapid Scene Analysis. Pattern Analysis and Machine Intelligence, IEEE Transactions on. 20. 1254 - 1259. 10.1109/34.730558.
To try a simple example run the script try.py.
