The following Matlab demos are open source and can be provided through the Mathworks File Exchange website. Most of the provided code is related to audio analysis methods and image processing. In the follow you will find a list of some of the demos. A full list can be found at the Mathworks website.

Image Processing GUI	This is a GUI that demonstrates some basic image processing functionalities, e.g., color filtering, motion filtering, etc.
Silence removal in speech signals	This is a simple method for silence removal and segmentation of audio streams that contain speech.
Image retrieval - Query by Example Demo	This demo provides a simple query by image example method, based on HSV values.
Real Time Microphone and Camera data acquisition and audio-video processing	This Matlab-code is a demo for real-time audio and image processing.
Color Detection Using HSV Color Space (Training and Testing)	The provided Matlab functions demonstrate a simple method for training and testing a color detection.

The following links provide audio analysis demos written in Matlab. These demos are not available in the Mathworks website. In order to be able to run the Demos, one needs to have the Matlab Component Runtime installer installed.

Speech - Music Discrimination	This Demo is used for automatic segmentation and discrimination between speech and music of audio streams. The algorithmic parts of this demo have been published in journal [2] (see Publications).
Multi-class Audio Segmentation	This Demo is used for multi-class audio segmentation with respect to audio stemming from movies. Therefore, not only speech and music are recognized, but 8 classes in total. The classes' definition was motivated by the audio signals met in movies, while special attention was given to violent content of movies and respective audio sounds (e.g. gunshots).
