By Professor Jerry D. Gibson Ph.D. – UCSB Presents: The Compression of Everything
Everything you consume or create on your cell phone, laptop, or tablet is compressed or will be. Compression is fundamental to our media-rich society today but is largely hidden behind the physical and network distribution layers. Compression is the representation of a signal in digital form with as few bits as possible while retaining the quality required for the given application. The technologies used for voice, audio, still images, and video all differ but broadly consist of time or frequency domain decompositions, quantization, and lossless coding. The need for compression is established in this talk and details of the compression methods are outlined, with particular emphasis on the signal processing required. Developing compression applications for biological signals such as EEG, ECG, and EMG are discussed.
