WAVE-UNET: Wavelength based Image Reconstruction method using attention UNET for OCT images

Autor: Viqar, Maryam, Sahin, Erdem, Madjarova, Violeta, Stoykova, Elena, Hong, Keehoon

In this work, we propose to leverage a deep-learning (DL) based reconstruction framework for high quality Swept-Source Optical Coherence Tomography (SS-OCT) images, by incorporating wavelength ({\lambda}) space interferometric fringes. Generally, the

Denoising OCT Images Using Steered Mixture of Experts with Multi-Model Inference

Autor: Özkan, Aytaç, Stoykova, Elena, Sikora, Thomas, Madjarova, Violeta

In Optical Coherence Tomography (OCT), speckle noise significantly hampers image quality, affecting diagnostic accuracy. Current methods, including traditional filtering and deep learning techniques, have limitations in noise reduction and detail pre

Modified watershed approach for segmentation of complex optical coherence tomographic images

Autor: Viqar, Maryam, Madjarova, Violeta, Stoykova, Elena

Publikováno v: Journal of International Scientific Publications 2022

Watershed segmentation method has been used in various applications. But many a times, due to its over-segmentation attributes, it underperforms in several tasks where noise is a dominant source. In this study, Optical Coherence Tomography images hav

Deep Learning based Segmentation of Optical Coherence Tomographic Images of Human Saphenous Varicose Vein

Autor: Viqar, Maryam, Madjarova, Violeta, Yadav, Amit Kumar, Pashkuleva, Desislava, Machikhin, Alexander S.

Deep-learning based segmentation model is proposed for Optical Coherence Tomography images of human varicose vein based on the U-Net model employing atrous convolution with residual blocks, which gives an accuracy of 0.9932.

Opto-UNet: Optimized UNet for Segmentation of Varicose Veins in Optical Coherence Tomography

Autor: Viqar, Maryam, Madjarova, Violeta, Baghel, Vipul, Stoykova, Elena

Human veins are important for carrying the blood from the body-parts to the heart. The improper functioning of the human veins may arise from several venous diseases. Varicose vein is one such disease wherein back flow of blood can occur, often resul
