Explicit visual prompting for low-level structure segmentations

W Liu, X Shen, CM Pun, X Cun - Proceedings of the IEEE …, 2023 - openaccess.thecvf.com
We consider the generic problem of detecting low-level structures in images, which includes
segmenting the manipulated parts, identifying out-of-focus pixels, separating shadow …

Edge-based defocus blur estimation with adaptive scale selection

A Karaali, CR Jung - IEEE Transactions on Image Processing, 2017 - ieeexplore.ieee.org
Objects that do not lie at the focal distance of a digital camera generate defocused regions in
the captured image. This paper presents a new edge-based method for spatially varying …

W Zhao, B Zheng, Q Lin, H Lu - Proceedings of the IEEE …, 2019 - openaccess.thecvf.com
Defocus blur detection (DBD) is a fundamental yet challenging topic, since the
homogeneous region is obscure and the transition from the focused area to the unfocused …

Explicit visual prompting for universal foreground segmentations

W Liu, X Shen, CM Pun, X Cun - arXiv preprint arXiv:2305.18476, 2023 - arxiv.org
Foreground segmentation is a fundamental problem in computer vision, which includes

Defocus blur detection via depth distillation

X Cun, CM Pun - Computer Vision–ECCV 2020: 16th European …, 2020 - Springer
Abstract Defocus Blur Detection (DBD) aims to separate in-focus and out-of-focus regions
from a single image pixel-wisely. This task has been paid much attention since bokeh effects …

Deep multi-scale feature learning for defocus blur estimation

A Karaali, N Harte, CR Jung - IEEE Transactions on Image …, 2022 - ieeexplore.ieee.org
This paper presents an edge-based defocus blur estimation method from a single defocused
image. We first distinguish edges that lie at depth discontinuities (called depth edges, for …

Image retargeting quality assessment based on saliency-driven classification

Z Tang, J Yao - Signal Processing: Image Communication, 2022 - Elsevier
The overall geometric distortions of the visually prominent contents in resized images are
sensitive to human perception. But the existing image retargeting quality assessment (IRQA) …

Noise-immune image blur detection via sequency spectrum truncation

X Liang, X Wang, L Lyu, Y Han, J Zheng, W Guo… - Complex & Intelligent …, 2022 - Springer
Blur detection is aimed to differentiate the blurry and sharp regions from a given image. This
task has attracted much attention in recent years due to its importance in computer vision …
