Asymmetrical occlusion handling using graph cut for multi-view stereo

, 2005
Occlusion is usually modelled in two images symmetrically in previous stereo algorithms which cannot work for multi-view stereo efficiently. In this paper, we present a novel formulation that handles occlusion using only one depth map in an asymmetrical ...

SemanticST: A Scalable Multi‐Contextual Graph Learning Framework for Uncovering Spatial Niches and Robust Multi‐Sample Integration in Spatial Transcriptomics

Advanced Science, EarlyView.
Technical limitations often let dominant signals overshadow rare cell types and fine‐grained heterogeneity in spatial transcriptomics. SemanticST, a graph neural network using multi‐semantic graph fusion and a novel min‐cut loss, recovers these subtle patterns.

An interpretable reliability-aware view selection framework for satellite-based deep MVS reconstruction

International Journal of Digital Earth
Reliable view selection is essential for accurate deep multi-view stereo (MVS) reconstruction from satellite imagery. However, existing strategies mainly rely on acquisition metadata or simplified geometric criteria and therefore cannot adequately ...

Parallax‐based second‐order mixed attention for stereo image super‐resolution

IET Computer Vision, 2022
Stereo image pairs can effectively enhance the performance of super‐resolution (SR) since both intra‐view and cross‐view information can be used. However, exploiting cross‐view information accurately is extremely challenging.

Deep Learning‐Driven Discovery and Engineering of an Efficient PETase for Depolymerization and Detoxification of PET Microplastics Under Physiological Conditions

Advanced Science, EarlyView.
A deep learning–driven pipeline mining 246 million protein sequences uncovers AhPETase, an evolutionarily distinct PET hydrolase. Engineered variant AhPETaseM1 degrades post‐consumer PET microplastics under physiological conditions and reverses microplasticinduced cytotoxicity in human lung and colon cells, establishing enzymatic microplastic ...

Robust multi-view stereo without matching [PDF]

2009 IEEE 12th International Conference on Computer Vision Workshops, ICCV Workshops, 2009
This paper proposes a robust algorithm that finds a proxy surface from a series of calibrated pictures of an object without assuming any of its reflectance properties. This proxy is optimized to reduce view interpolation errors by globally minimizing the frequency criterion proposed in [1].
