SAR Despeckling Using Overcomplete Convolutional Networks
Malsha V. Perera, Wele Gedara Chaminda Bandara, Jeya Maria Jose Valanarasu +1
Synthetic Aperture Radar (SAR) despeckling is an important problem in remote sensing as speckle degrades SAR images, affecting downstream tasks like detection and segmentation. Rec…
Transformer-based SAR Image Despeckling
Malsha V. Perera, Wele Gedara Chaminda Bandara, Jeya Maria Jose Valanarasu +1
Synthetic Aperture Radar (SAR) images are usually degraded by a multiplicative noise known as speckle which makes processing and interpretation of SAR images difficult. In this pap…
A Thickness Sensitive Vessel Extraction Framework for Retinal and Conjunctival Vascular Tortuosity Analysis
Ashwin De Silva, Malsha V. Perera, Navodini Wijethilake +3
Systemic diseases such as diabetes, hypertension, atherosclerosis are among the leading causes of annual human mortality rate. It is suggested that retinal and conjunctival vascula…
A Joint Convolutional and Spatial Quad-Directional LSTM Network for Phase Unwrapping
Malsha V. Perera, Ashwin De Silva
Phase unwrapping is a classical ill-posed problem which aims to recover the true phase from wrapped phase. In this paper, we introduce a novel Convolutional Neural Network (CNN) th…
Low-cost Active Dry-Contact Surface EMG Sensor for Bionic Arms
Asma M. Naim, Kithmin Wickramasinghe, Ashwin De Silva +3
Surface electromyography (sEMG) is a popular bio-signal used for controlling prostheses and finger gesture recognition mechanisms. Myoelectric prostheses are costly, and most comme…
Real-Time Hand Gesture Recognition Using Temporal Muscle Activation Maps of Multi-Channel sEMG Signals
Ashwin De Silva, Malsha V. Perera, Kithmin Wickramasinghe +3
Accurate and real-time hand gesture recognition is essential for controlling advanced hand prostheses. Surface Electromyography (sEMG) signals obtained from the forearm are widely…
