Summary: Existing methods for predicting discomfort in stereoscopic images may not work well because extracting discomfort features from statistical information of stereoscopic images is difficult due to the complex mechanism of human binocular vision. In this study, we propose an end-to-end trainable dual-stream multi-level interactive network for stereoscopic image discomfort prediction. Our method extracts fusion and difference features at multiple levels through a multi-level interaction network, and simulates the complex visual interaction mechanism of the human visual system by concatenating low, medium, and high-level feature maps. Experimental results show that our approach outperforms existing prediction models on the IEEE-SA dataset and NBU-S3D dataset.

Summary: This paper proposes an objective image retargeting quality assessment (IRQA) metric based on both local and global geometric distortions (LGGD). It introduces a sketch token-based local edge descriptor (ST-LED) to represent geometric-aware features and applies it to both source and retargeted images for edge pattern representation. The proposed LGGD metric focuses on geometric distortion and is further fused with an existing IRQA metric to improve overall image retargeting quality assessment.

Summary: This paper proposes a clustering-based TMO method by embedding human visual system models to adapt to different HDR scenes. The method reduces computational complexity using a hierarchical scheme for clustering and enhances local contrast by superimposing details and controlling color saturation by limiting the adaptive saturation parameter. Experimental results show that the proposed method achieves improvements in generating high quality tone-mapped images compared to competing methods.
