Title:

Bio-inspired trainable features for image and sound processing

Abstract:

Representation learning is a fundamental aspect of Pattern Recognition and consists of learning features from training samples instead of engineering hand-crafted data representations, which usually require domain knowledge. Recent deep learning approaches require very large amount of training data to learn effective features.

In this talk, we will discuss the trainable feature extractors COSFIRE and COPE, used to learn effective representations from a small number of training examples in applications of image and audio processing. Their design is inspired by some functions of the visual and auditory systems of the brain. We will focus on the use of COSFIRE features for the delineation of elongated structures in images (e.g. blood vessels, rivers and roads in aerial images) and of the COPE features for the detection and classification of audio events in noisy environments.
