Systems, Methods, and Computer Program Products for Compression, Digital Watermarking, and Other Digital Signal Processing for Audio and/or Video Applications

Abstract

Systems, methods, and computer program products are provided for performing digital signal processing. According to one embodiment, the digital signal processing may include obtaining a first set of digitized coefficients from source data and determining a best-fit distribution of a generalized Gaussian distribution for the set of digitized coefficients. The digital signal processing may further include applying a quantization algorithm to the first set of plurality of digitized coefficients to obtain a second set of quantizers, wherein the quantization algorithm is based at least in part on the determined best-fit distribution, and providing second set of quantizers as a compressed representation of the source data. According to another embodiment, the digital signal processing may include retrieving suspected encoded data, determining at least one parameter of a generalized Gaussian distribution for the suspected encoded data, determining a digital watermark within the suspected encoded data based at least in part on at least one the determined parameter, and extracting the digital watermark from the suspected encoded data.
