Image Segmentation of Brain MRI Based on LTriDP and Superpixels of Improved SLIC

open access: yesBrain Sciences, 2020
Non-uniform gray distribution and blurred edges often result in bias during the superpixel segmentation of medical images of magnetic resonance imaging (MRI).

Superpixels: An evaluation of the state-of-the-art [PDF]

open access: yesComputer Vision and Image Understanding, 2018
Superpixels group perceptually similar pixels to create visually meaningful entities while heavily reducing the number of primitives for subsequent processing steps. As of these properties, superpixel algorithms have received much attention since their naming in 2003. By today, publicly available superpixel algorithms have turned into standard tools in

Salient Object Segmentation Based on Superpixel and Background Connectivity Prior

open access: yesIEEE Access, 2018
Salient object segmentation is well known for detecting and segmenting objects using saliency map as input. In this paper, we propose a salient object segmentation method which integrates saliency, superpixel, and background connectivity prior.

Multiple Superpixel Graphs Learning Based on Adaptive Multiscale Segmentation for Hyperspectral Image Classification

open access: yesRemote Sensing, 2022
Hyperspectral image classification (HSIC) methods usually require more training samples for better classification performance. However, a large number of labeled samples are difficult to obtain because it is cost- and time-consuming to label an HSI in a ...

Superpixel-based color transfer [PDF]

open access: yes2017 IEEE International Conference on Image Processing (ICIP), 2017
In this work, we propose a fast superpixel-based color transfer method (SCT) between two images. Superpixels enable to decrease the image dimension and to extract a reduced set of color candidates. We propose to use a fast approximate nearest neighbor matching algorithm in which we enforce the match diversity by limiting the selection of the same ...

Superpixel-Based Unsupervised Hyperspectral Unmixing [PDF]

open access: yes, 2018
Recently, superpixel-based approaches have been proposed for hyperspectral unmixing. The basic assumption of this approach is that the superpixel over-segmentation segments the image into small homogeneous areas.

Updated Homogeneity Criteria Based Low-Dimensional Representation for Hyperspectral Unmixing

open access: yesIEEE Access
Superpixel-based approaches have been proposed for hyperspectral unmixing. The basic assumption of this approach is that the superpixel over-segmentation segments the image into small homogeneous areas.

Artificial Intelligence in Dermatology: Current Applications and Future Directions

open access: yesJEADV Clinical Practice, EarlyView.
This scoping review of 56 studies maps AI applications in dermatology. Image‐based classification for skin cancer detection dominates (48%), followed by clinical decision support (21%), teledermatology triage (11%), and predictive analytics (11%). While deep learning algorithms demonstrate diagnostic performance comparable to clinicians in controlled ...

Integration of Refractive Microlenses on BP/MoS2 Photodiodes for Enhanced Infrared Photodetection

open access: yesSmall, EarlyView.
This study demonstrates the successful integration of black phosphorus/molybdenum disulfide infrared photodetectors with refractive microlenses to significantly enhance detection. The design achieves a 20‐fold photocurrent enhancement, enabling a room‐temperature detectivity of 1.83 × 109 cmHz1/2W−1, and demonstrates high‐resolution (1023 × 768) single‐
