2D–3D geometric fusion network using multi-neighbourhood graph convolution for RGB-D indoor scene classification
(Elsevier, 2021-12)
Article
Open AccessMulti-modal fusion has been proved to help enhance the performance of scene classification tasks. This paper presents a 2D-3D Fusion stage that combines 3D Geometric Features with 2D Texture Features obtained by 2D ... -
3D hierarchical optimization for multi-view depth map coding
(2017-11-28)
Article
Open AccessDepth data has a widespread use since the popularity of high resolution 3D sensors. In multi-view sequences, depth information is used to supplement the color data of each view. This article proposes a joint encoding of ... -
Accelerating super-resolution for 4K upscaling
(Institute of Electrical and Electronics Engineers (IEEE), 2015)
Conference report
Restricted access - publisher's policyThis paper presents a fast Super-Resolution (SR) algorithm based on a selective patch processing. Motivated by the observation that some regions of images are smooth and unfocused and can be properly upscaled with fast ... -
Advanced visual rendering, gesture-based interaction and distributed delivery for immersive and interactive media services
(2011)
Conference report
Open AccessThe media industry is currently being pulled in the often-opposing directions of increased realism (high resolution, stereoscopic, large screen) and personalisation (selection and control of content, availability on many ... -

AmodalAppleSize_RGB-D dataset: RGB-D images of apple trees annotated with modal and amodal segmentation masks for fruit detection, visibility and size estimation
(Elsevier, 2024-02)
Article
Open AccessThe present dataset comprises a collection of RGB-D apple tree images that can be used to train and test computer vision-based fruit detection and sizing methods. This dataset encompasses two distinct sets of data obtained ... -
An epipolar-constrained prior for efficient search in multi-view scenarios
(Institute of Electrical and Electronics Engineers (IEEE), 2014)
Conference report
Restricted access - publisher's policyIn this paper we propose a novel framework for fast exploitation of multi-view cues with applicability in different image processing problems. In order to bring our proposed framework into practice, an epipolar-constrained ... -
Antipodally invariant metrics for fast regression-based super-resolution
(2016-03-31)
Article
Open AccessDictionary-based super-resolution (SR) algorithms usually select dictionary atoms based on the distance or similarity metrics. Although the optimal selection of the nearest neighbors is of central importance for such ... -

Bayesian region selection for adaptive dictionary-based Super-Resolution
(2013)
Conference lecture
Open AccessThe performance of dictionary-based super-resolution (SR) strongly depends on the contents of the training dataset. Nevertheless, many dictionary-based SR methods randomly select patches from of a larger set of training ... -
Channel redundancy and overlap in convolutional neural networks with channel-wise NNK graphs
(Institute of Electrical and Electronics Engineers (IEEE), 2022)
Conference report
Open AccessFeature spaces in the deep layers of convolutional neural networks (CNNs) are often very high-dimensional and difficult to inter-pret. However, convolutional layers consist of multiple channels that are activated by different ... -
Channel-wise early stopping without a validation set via NNK polytope interpolation
(2021)
Conference report
Open AccessState-of-the-art neural network architectures continue to scale in size and deliver impressive generalization results, although this comes at the expense of limited interpretability. In particular, a key challenge is to ... -
