Digital Signals Processing Exercises

Multiple exercises regarding digital signals processing (audio and images)

1. Low-level audio classification

Implementation of the Zero-Crossing Rate (ZCR) feature to describe a single-channel audio signal

2. Frequency-based audio analysis

Implementation of three distinct feature extractors based respectively on Spectrogram, Mel Spectrogram, and MFCC

3. Low-level image processing

Experiments with the compression of a color image by blurring the channels of the YCbCr representation

4. Photo stitching

Implementation of a script for stitching two images
