How Images Inspire Poems: Generating Classical Chinese Poetry from Images with Memory Networks

no code implementations8 Mar 2018 Linli Xu, Liang Jiang, Chuan Qin, Zhe Wang, Dongfang Du

Generating poetry from images is much more challenging than generating poetry from text, since images contain very rich visual information which cannot be described completely using several keywords, and a good poem should convey the image accurately.

Statistical Analysis of Signal-Dependent Noise: Application in Blind Localization of Image Splicing Forgery

no code implementations30 Oct 2020 Mian Zou, Heng Yao, Chuan Qin, Xinpeng Zhang

Through statistical analysis of the SDN model, we assume that noise can be modeled as a Gaussian approximation for a certain brightness and propose a likelihood model for a noise level function.

Perceptual Robust Hashing for Color Images with Canonical Correlation Analysis

no code implementations8 Dec 2020 Xinran Li, Chuan Qin, Zhenxing Qian, Heng Yao, Xinpeng Zhang

Local color features of significant corner points on outer boundaries of ring-ribbons are extracted through color vector angles (CVA), and color low-order moments (CLMs) is utilized to extract global color features.

Adam revisited: a weighted past gradients perspective

no code implementations1 Jan 2021 Hui Zhong, Zaiyi Chen, Chuan Qin, Zai Huang, Vincent W. Zheng, Tong Xu, Enhong Chen

Though many algorithms, such as AMSGRAD and ADAMNC, have been proposed to fix the non-convergence issues, achieving a data-dependent regret bound similar to or better than ADAGRAD is still a challenge to these methods.

Adversarial Examples Detection beyond Image Space

1 code implementation23 Feb 2021 Kejiang Chen, Yuefeng Chen, Hang Zhou, Chuan Qin, Xiaofeng Mao, Weiming Zhang, Nenghai Yu

To detect both few-perturbation attacks and large-perturbation attacks, we propose a method beyond image space by a two-stream architecture, in which the image stream focuses on the pixel artifacts and the gradient stream copes with the confidence artifacts.

Regularizing Variational Autoencoder with Diversity and Uncertainty Awareness

1 code implementation24 Oct 2021 Dazhong Shen, Chuan Qin, Chao Wang, HengShu Zhu, Enhong Chen, Hui Xiong

As one of the most popular generative models, Variational Autoencoder (VAE) approximates the posterior of latent variables based on amortized variational inference.
