An Interactive Annotation Tool for Perceptual Video Compression
Evgenya Pergament, Pulkit Tandon, Kedar Tatwawadi +6
Human perception is at the core of lossy video compression and yet, it is challenging to collect data that is sufficiently dense to drive compression. In perceptual quality assessm…
ELF-VC: Efficient Learned Flexible-Rate Video Coding
Oren Rippel, Alexander G. Anderson, Kedar Tatwawadi +3
While learned video codecs have demonstrated great promise, they have yet to achieve sufficient efficiency for practical deployment. In this work, we propose several novel ideas fo…
Reducing latency and bandwidth for video streaming using keypoint extraction and digital puppetry
Roshan Prabhakar, Shubham Chandak, Carina Chiu +4
COVID-19 has made video communication one of the most important modes of information exchange. While extensive research has been conducted on the optimization of the video streamin…
DZip: improved general-purpose lossless compression based on novel neural network modeling
Mohit Goyal, Kedar Tatwawadi, Shubham Chandak +1
We consider lossless compression based on statistical data modeling followed by prediction-based encoding, where an accurate statistical model for the input data leads to substanti…
LFZip: Lossy compression of multivariate floating-point time series data via improved prediction
Shubham Chandak, Kedar Tatwawadi, Chengtao Wen +3
Time series data compression is emerging as an important problem with the growth in IoT devices and sensors. Due to the presence of noise in these datasets, lossy compression can o…
Tutorial on algebraic deletion correction codes
Kedar Tatwawadi, Shubham Chandak
The deletion channel is known to be a notoriously diffcult channel to design error-correction codes for. In spite of this difficulty, there are some beautiful code constructions wh…
