A Spectral Filter Array Camera for Clinical Monitoring and Diagnosis: Proof of Concept for Skin Oxygenation Imaging
(Journal article; Peer reviewed, 2019)The emerging technology of spectral filter array (SFA) cameras has great potential forclinical applications, due to its unique capability for real time spectral imaging, at a reasonable cost.This makes such cameras ... -
Bidirectional Reflectance Measurement and Reflection Model Fitting of Complex Materials Using an Image-Based Measurement Setup
(Journal article; Peer reviewed, 2018)Materials with a complex visual appearance, like goniochromatic or non-diffuse, are widely used for the packaging industry. Measuring optical properties of such materials requires a bidirectional approach, and therefore, ... -
Detection of Orientation-Modulation Embedded Data in Color Printed Natural Images
(Journal article; Peer reviewed, 2018)This article addresses methods for detection of orientation-modulation data embedded in color dispersed-dot-halftone images. Several state-of-the-art methods for detection of orientation-embedded data in printed halftone ... -
HFM: A Hybrid Feature Model Based on Conditional Auto Encoders for Zero-Shot Learning
(Peer reviewed; Journal article, 2022)Zero-Shot Learning (ZSL) is related to training machine learning models capable of classifying or predicting classes (labels) that are not involved in the training set (unseen classes). A well-known problem in Deep Learning ... -
Individualised Halo-Free Gradient-Domain Colour Image Daltonisation
(Peer reviewed; Journal article, 2020)Daltonisation refers to the recolouring of images such that details normally lost by colour vision deficient observers become visible. This comes at the cost of introducing artificial colours. In a previous work, we presented ... -
Local Indicators of Spatial Autocorrelation (LISA): Application to Blind Noise-Based Perceptual Quality Metric Index for Magnetic Resonance Images
(Journal article; Peer reviewed, 2019)Noise-based quality evaluation of MRI images is highly desired in noise-dominant environments. Current noise-based MRI quality evaluation methods have drawbacks which limit their effective performance. Traditional ... -
Mapping Quantitative Observer Metamerism of Displays
(Journal article; Peer reviewed, 2023)Observer metamerism (OM) is the name given to the variability between the color matches that individual observers consider accurate. The standard color imaging approach, which uses color-matching functions of a single ... -
On the Quantification of Visual Texture Complexity
(Peer reviewed; Journal article, 2022)Complexity is one of the major attributes of the visual perception of texture. However, very little is known about how humans visually interpret texture complexity. A psychophysical experiment was conducted to visually ... -
PedNet: A Spatio-Temporal Deep Convolutional Neural Network for Pedestrian Segmentation
(Journal article; Peer reviewed, 2018)Articulation modeling, feature extraction, and classification are the important components of pedestrian segmentation. Usually, these components are modeled independently from each other and then combined in a sequential ... -
Robust 3D Face Reconstruction Using One/Two Facial Images
(Peer reviewed; Journal article, 2021)Being able to robustly reconstruct 3D faces from 2D images is a topic of pivotal importance for a variety of computer vision branches, such as face analysis and face recognition, whose applications are steadily growing. ... -
A Robust Tensor-Based Submodule Clustering for Imaging Data Using l1/2 Regularization and Simultaneous Noise Recovery via Sparse and Low Rank Decomposition Approach
(Peer reviewed; Journal article, 2021)The massive generation of data, which includes images and videos, has made data management, analysis, information extraction difficult in recent years. To gather relevant information, this large amount of data needs to be ... -
Single-Image-Based 3D Reconstruction of Endoscopic Images
(Journal article; Peer reviewed, 2024)A wireless capsule endoscope (WCE) is a medical device designed for the examination of the human gastrointestinal (GI) tract. Three-dimensional models based on WCE images can assist in diagnostics by effectively detecting ... -
Spectral Reflectance Estimation from Camera Responses Using Local Optimal Dataset
(Peer reviewed; Journal article, 2023)A novel method is proposed to estimate surface-spectral reflectance from camera responses using a local optimal reflectance dataset. We adopt a multispectral imaging system that involves an RGB camera capturing multiple ... -
Stochastic Capsule Endoscopy Image Enhancement
(Journal article; Peer reviewed, 2018)Capsule endoscopy, which uses a wireless camera to take images of the digestive tract, is emerging as an alternative to traditional colonoscopy. The diagnostic values of these images depend on the quality of revealed ... -
Unsupervised Clustering of Hyperspectral Paper Data Using t-SNE
(Peer reviewed; Journal article, 2020)For a suspected forgery that involves the falsification of a document or its contents, the investigator will primarily analyze the document’s paper and ink in order to establish the authenticity of the subject under ... -
Variational Anisotropic Gradient-Domain Image Processing
(Peer reviewed; Journal article, 2021)Gradient-domain image processing is a technique where, instead of operating directly on the image pixel values, the gradient of the image is computed and processed. The resulting image is obtained by reintegrating the ... -
Visually Significant Dimensions and Parameters for Gloss
(Peer reviewed; Journal article, 2023)The appearance of a surface depends on four main appearance attributes, namely color, gloss, texture, and translucency. Gloss is an important attribute that people use to understand surface appearance, right after color. ...
