Task-Aware Quantization Network for JPEG Image Compression

no code implementations ECCV 2020 Jinyoung Choi, Bohyung Han

We propose to learn a deep neural network for JPEG image compression, which predicts image-specific optimized quantization tables fully compatible with the standard JPEG encoder and decoder.

A Training-Free Defense Framework for Robust Learned Image Compression

no code implementations22 Jan 2024 Myungseo Song, Jinyoung Choi, Bohyung Han

We study the robustness of learned image compression models against adversarial attacks and present a training-free defense technique based on simple image transform functions.

Observation-Guided Diffusion Probabilistic Models

1 code implementation6 Oct 2023 Junoh Kang, Jinyoung Choi, Sungik Choi, Bohyung Han

We propose a novel diffusion-based image generation method called the observation-guided diffusion probabilistic model (OGDM), which effectively addresses the tradeoff between quality control and fast sampling.

Variable-Rate Deep Image Compression through Spatially-Adaptive Feature Transform

1 code implementation ICCV 2021 Myungseo Song, Jinyoung Choi, Bohyung Han

In addition, the proposed framework allows us to perform task-aware image compressions for various tasks, e. g., classification, by efficiently estimating optimized quality maps specific to target tasks for our encoding network.
