Exploring the Rate-Distortion-Complexity Optimization in Neural Image Compression

no code implementations12 May 2023 Yixin Gao, Runsen Feng, Zongyu Guo, Zhibo Chen

By quantifying the decoding complexity as a factor in the optimization goal, we are now able to precisely control the RDC trade-off and then demonstrate how the rate-distortion performance of neural image codecs could adapt to various complexity demands.

Semantically Structured Image Compression via Irregular Group-Based Decoupling

no code implementations ICCV 2023 Ruoyu Feng, Yixin Gao, Xin Jin, Runsen Feng, Zhibo Chen

Nevertheless, they divide the input image into multiple rectangular regions according to semantics and ignore avoiding information interaction among them, causing waste of bitrate and distorted reconstruction of region boundaries.

Image Coding for Machines with Omnipotent Feature Learning

no code implementations5 Jul 2022 Ruoyu Feng, Xin Jin, Zongyu Guo, Runsen Feng, Yixin Gao, Tianyu He, Zhizheng Zhang, Simeng Sun, Zhibo Chen

Learning a kind of feature that is both general (for AI tasks) and compact (for compression) is pivotal for its success.

On Front-end Gain Invariant Modeling for Wake Word Spotting

no code implementations13 Oct 2020 Yixin Gao, Noah D. Stein, Chieh-Chi Kao, Yunliang Cai, Ming Sun, Tao Zhang, Shiv Vitaladevuni

Since the WW model is trained with the AFE-processed audio data, its performance is sensitive to AFE variations, such as gain changes.

Towards Data-efficient Modeling for Wake Word Spotting

no code implementations13 Oct 2020 Yixin Gao, Yuriy Mishchenko, Anish Shah, Spyros Matsoukas, Shiv Vitaladevuni

Wake word (WW) spotting is challenging in far-field not only because of the interference in signal transmission but also the complexity in acoustic environments.
