TL;DR: The Multimodal Brain Tumor Image Segmentation Benchmark (BRATS) as mentioned in this paper was organized in conjunction with the MICCAI 2012 and 2013 conferences, and twenty state-of-the-art tumor segmentation algorithms were applied to a set of 65 multi-contrast MR scans of low and high grade glioma patients.
Book ChapterDOI
Decision forests for tissue-specific segmentation of high-grade gliomas in multi-channel MR.
Darko Zikic,Ben Glocker,Ender Konukoglu,Antonio Criminisi,Çağatay Demiralp,Jamie Shotton,Owen M. Thomas,Tilak Das,Raj Jena,Stephen J. Price +9 more
TL;DR: The discriminative approach is based on decision forests using context-aware spatial features, and integrates a generative model of tissue appearance, by using the probabilities obtained by tissue-specific Gaussian mixture models as additional input for the forest.
Journal ArticleDOI
Visualizing diffusion tensor MR images using streamtubes and streamsurfaces
TL;DR: Expert feedback from doctors studying changes in white-matter structures after gamma-knife capsulotomy and preoperative planning for brain tumor surgery shows that streamtubes correlate well with major neural structures, the 2D section and geometric landmarks are important in understanding the visualization, and the stereo and interactivity from the virtual environment aid inUnderstanding the complex geometric models.

Sherlock: A Deep Learning Approach to Semantic Data Type Detection
Madelon Hulsebos,Kevin Hu,Michiel A. Bakker,Emanuel Zgraggen,Arvind Satyanarayan,Tim Kraska,Çağatay Demiralp,César A. Hidalgo +7 more
TL;DR: Sherlock is introduced, a multi-input deep neural network for detecting semantic types that achieves a support-weighted F$_1 score of $0.89, exceeding that of machine learning baselines, dictionary and regular expression benchmarks, and the consensus of crowdsourced annotations.
Journal ArticleDOI
Learning Perceptual Kernels for Visualization Design.
TL;DR: This work introduces perceptual kernels: distance matrices derived from aggregate perceptual judgments, which represent perceptual differences between and within visual variables in a reusable form that is directly applicable to visualization evaluation and automated design.
