QVRF: A Quantization-error-aware Variable Rate Framework for Learned Image Compression 简介 在本文中,作者提出了一种基于端到端图像压缩网络的量化误差感知可变速率框架 (QVRF)。具体来说,QVRF 定义了一个单变量量化调整因子来控制所有潜在变量的量化误差,从而在单个模型中实现可变比特率。作者建立了量化调整因子...
We propose a versatile deep image compression network based on Spatial Feature Transform (SFT arXiv:1804.02815 ), which takes a source image and a corresponding quality map as inputs and produce a compressed image with variable rates. Our model covers a wide range of compression rates using a ...
However, in order to obtain enough bit rates to fit the performance curve, there is always a severe computational burden, especially for multispectral image compression. This problem arises not only because the complexity of the algorithm is deepening, but also repeated training with rate-distortion...

Variable rate is a requirement for flexible and adaptable image and video compression. However, deep image compression methods (DIC) are optimized for a single fixed rate-distortion (R-D) tradeoff. While this can be addressed by training multiple models for different tradeoffs, the memory requireme...
To obtain variable rate image compression, multiple times training a CNN-based model is required. But scaling or tuning the bottleneck representation causes degradation in compression performance at low bit rates. To combat this, Yang et al. [149] proposed a variable rate RD optimization by ...
