Point cloud upsampling has been extensively studied, however, the existing approaches suffer from the losing of structural information due to neglect of spatial dependencies between points. In this work, we propose PU-GAT, a novel 3D point cloud ...

Image enhancement is an indispensable pre-processing step for several image processing applications. Mainly, histogram equalization is one of the widespread techniques used by various researchers to improve the image quality by expanding the ...

• This research reduces artefacts in homogeneous background images.
• Employment of adaptive histogram trimming reduces unnatural appearance.
• Local improvement in DCT domain reduces information loss during equalisation.
• Formulation ...

Reconstructing 3D human pose and body shape from monocular images or videos is a fundamental task for comprehending human dynamics. Frame-based methods can be broadly categorized into two fashions: those regressing parametric model parameters (...

• Novel decomposition method for unordered point clouds based on the wavelet transform.
• LOD scheme capable of progressive data streaming.
• Blending scheme for continuous LOD interpolation and visualization.
• Potential use for lossy ...

This paper aims at extending the method of Zhang et al. (2023) to produce not only portrait bas-reliefs from single photographs, but also high-depth reliefs with reasonable depth ordering. We cast this task as a problem of style-aware photo-to-...
