Real-Time Adaptive Video Compression

Real-Time Adaptive Video Compression

Compressive sensing has been widely applied to problems in signal and imaging processing. In this work, we present an algorithm for predicting optimal real-time compression rates for video. The video data we consider is spatially compressed during the acquisition process, unlike in many of the standard methods. Rather than temporally compressing the frames at a fixed rate, our algorithm adaptiv...

Real-Time Adaptive Image Compression

Streaming of digital media makes 70% of internet traffic, and is projected to reach 80% by 2020 (CIS, 2015). However, it has been challenging for existing commercial compression algorithms to adapt to the growing demand and the changing landscape of requirements and applications. While digital media are transmitted in a wide variety of settings, the available codecs are “one-size-fits-all”: the...

Real - Time Video Compression Using Di erentialVector

|This paper describes hardware that has been built to compress video in real time using full-search vector quan-tization (VQ). This architecture implements a diierential-vector-quantization (DVQ) algorithm and features a special-purpose digital associative memory, the VAMPIRE chip, which has been fabricated in 2m CMOS. We describe the DVQ algorithm, its adaptations for sampled NTSC composite co...

Volumetric Video Compression for Real-Time Playback

In this paper, we describe a compression scheme for volumetric video data(3D space 1D time) where each frame of the volume is decompressed and rendered in real-time. Since even one frame size of volume is very large, run-time decompression can be a bottleneck for real-time playback of time-varying volume data. To increase the run-time decompression speed and compression ratio, we decompose the ...
