Deep Shape-Texture Statistics for Completely Blind Image Quality Evaluation

no code implementations16 Jan 2024 Yixuan Li, Peilin Chen, Hanwei Zhu, Keyan Ding, Leida Li, Shiqi Wang

The perceptual quality is quantified by the variant Mahalanobis Distance between the inner and outer Shape-Texture Statistics (DSTS), wherein the inner and outer statistics respectively describe the quality fingerprints of the distorted image and natural images.

InstructProtein: Aligning Human and Protein Language via Knowledge Instruction

no code implementations5 Oct 2023 Zeyuan Wang, Qiang Zhang, Keyan Ding, Ming Qin, Xiang Zhuang, Xiaotong Li, Huajun Chen

To address this challenge, we propose InstructProtein, an innovative LLM that possesses bidirectional generation capabilities in both human and protein languages: (i) taking a protein sequence as input to predict its textual function description and (ii) using natural language to prompt protein sequence generation.

A Simple Method to improve Initialization Robustness for Active Contours driven by Local Region Fitting Energy

no code implementations28 Feb 2018 Keyan Ding, Linfang Xiao

Active contour models based on local region fitting energy can segment images with intensity inhomogeneity effectively, but their segmentation results are easy to error if the initial contour is inappropriate.
