SAR Image Change Detection via Multiple-Window Processing with Structural Similarity

open access: yesSensors, 2021
In this paper, a synthetic aperture radar (SAR) change detection approach is proposed based on a structural similarity index measure (SSIM) and multiple-window processing (MWP). The proposed scheme is performed in two steps: (1) generation of a coherence

Efficient Reconstruction of Low Photon Count Images from a High Speed Camera

open access: yesPhotonics, 2022
Challenging imaging applications requiring ultra-short exposure times or imaging in photon-starved environments can acquire extremely low numbers of photons per pixel, (1 MHz) and low incident photon flux (

Optimal structural similarity constraint for reversible data hiding

open access: yes网络与信息安全学报, 2016
Most reversible data hiding (RDH) techniques have been evaluated by PSNR,which is based on MSE.Unfortunately,MSE turns out to be an extremely poor measure when the purpose is to predict perceived signal fidel-ity or quality.The structural similarity ...

Enhanced Deep-Learning-Based Automatic Left-Femur Segmentation Scheme with Attribute Augmentation

open access: yesSensors, 2023
This research proposes augmenting cropped computed tomography (CT) slices with data attributes to enhance the performance of a deep-learning-based automatic left-femur segmentation scheme. The data attribute is the lying position for the left-femur model.

FenceTalk: Exploring False Negatives in Moving Object Detection

open access: yesAlgorithms, 2023
Deep learning models are often trained with a large amount of labeled data to improve the accuracy for moving object detection in new fields. However, the model may not be robust enough due to insufficient training data in the new field, resulting in ...

Modified Block Sparse Bayesian Learning-Based Compressive Sensing Scheme for EEG Signals [PDF]

open access: yesInternational Journal of Electronics and Telecommunications, 2021
Advancement in medical technology creates some issues related to data transmission as well as storage. In real-time processing, it is too tedious to limit the flow of data as it may reduce the meaningful information too.
