SyCoCa: Symmetrizing Contrastive Captioners with Attentive Masking for Multimodal Alignment

ICML 2024poster

Multimodal alignment between language and vision is the fundamental topic in current vision-language model research. Contrastive Captioners (CoCa), as a representative method, integrates Contrastive Language-Image Pretraining (CLIP) and Image Caption (IC) into a unified framework, resulting in impre…

Robust Steganography without Embedding Based on Secure Container Synthesis and Iterative Message Recovery

IJCAI 2023poster

Synthesis-based steganography without embedding (SWE) methods transform secret messages to container images synthesised by generative networks, which eliminates distortions of container images and thus can fundamentally resist typical steganalysis tools. However, existing methods suffer from weak me…

Image Disentanglement Autoencoder for Steganography Without Embedding

CVPR 2022poster

Conventional steganography approaches embed a secret message into a carrier for concealed communication but are prone to attack by recent advanced steganalysis tools. In this paper, we propose Image DisEntanglement Autoencoder for Steganography (IDEAS) as a novel steganography without embedding (SWE…
