Abstract
This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for a high-performance and low-latency implementation of a wavelet-based image compression scheme. A processor may generate, in a single pass for each of a plurality of horizontal and vertical divisions of an image frame, a set of wavelet coefficients for the image frame based on a DWT. The processor may select a set of bits associated with the set of wavelet coefficients to remove based on an entropy coding process. The processor may serialize the set of wavelet coefficients, where the set of serialized wavelet coefficients do not include the set of bits. The processor may output, for a second device, a bitstream including the set of serialized wavelet coefficients.
