Fake-image detection with Robust Hashing
Miki Tanaka, Hitoshi Kiya
In this paper, we investigate whether robust hashing has a possibility to robustly detect fake-images even when multiple manipulation techniques such as JPEG compression are applie…
Multi-color balancing for correctly adjusting the intensity of target colors
Teruaki Akazawa, Yuma Kinoshita, Hitoshi Kiya
In this paper, we propose a novel multi-color balance method for reducing color distortions caused by lighting effects. The proposed method allows us to adjust three target-colors…
A Block-Permutation-Based Encryption Scheme with Independent Processing of RGB Components
Shoko Imaizumi, Hitoshi Kiya
This paper proposes a block-permutation-based encryption (BPBE) scheme for the encryption-then-compression (ETC) system that enhances the color scrambling. A BPBE image can be obta…
Extension of JPEG XS for Two-Layer Lossless Coding
Hiroyuki Kobayashi, Hitoshi Kiya
A two-layer lossless image coding method compatible with JPEG XS is proposed. JPEG XS is a new international standard for still image coding that has the characteristics of very lo…
A Noise-aware Enhancement Method for Underexposed Images
Chien-Cheng Chien, Yuma Kinoshita, Hitoshi Kiya
A novel method of contrast enhancement is proposed for underexposed images, in which heavy noise is hidden. Under low light conditions, images taken by digital cameras have low con…
Scene Segmentation-Based Luminance Adjustment for Multi-Exposure Image Fusion
Yuma Kinoshita, Hitoshi Kiya
We propose a novel method for adjusting luminance for multi-exposure image fusion. For the adjustment, two novel scene segmentation approaches based on luminance distribution are a…
