Fully automatic localization of anatomical structures in 2D and 3D radiological data sets is important in both computer aided diagnosis, and the rapid automatic processing of large amounts of data. We present a simple, accurate and fast approach with low computational complexity to find anatomical landmarks, based on a multi-scale regression codebook of informative image patches and encoded lan...

Image segmentation methods like active shape models, active appearance models or snakes require an initialisation that guarantees a considerable overlap with the object to be segmented. In this paper we present an approach that localises anatomical structures in a global manner by means ofMarkov Random Fields (MRF). It does not need initialisation, but finds the most plausible match of the quer...

In computer assisted surgery 3D models are now routinely used to plan and navigate a surgery. These models enhance the surgeon’s capability to decrease the invasiveness of surgical procedures and increase their accuracy and safety. Models obtained from specifically acquired CT scans have the disadvantage that they induce high radiation dose to the patient. In this paper we propose a novel metho...

ARTICLE HISTORY: Received 28 May 2014 Revised 7 June 2014 Accepted 30 June 2014 Automatic analysis of human facial expressions is one of the challenging problems in machine vision systems. It has many applications in humancomputer interactions such as, social signal processing, social robots, deceit detection, interactive video and behavior monitoring. In this paper, we develop a new method for...

BACKGROUND Even in resting state, the human brain generates functional signals (fMRI) with complex correlational structure. To simplify this structure, it is common to parcellate a standard brain into coarse chunks. Finer parcellations are considered less reproducible and informative, due to anatomical and functional variability of individual brains. NEW METHODS Grouping signals with similar ...

OBJECTIVE Conceptualization of the physical objects and spaces that constitute the human body at the macroscopic level of organization, specified as a machine-parseable ontology that, in its human-readable form, is comprehensible to both expert and novice users of anatomical information. DESIGN Conceived as an anatomical enhancement of the UMLS Semantic Network and Metathesaurus, the anatomic...

Each subject discipline has its own language. Many anatomical terms are based on Latin or Greek, so students unfamiliar with either and learning anatomy for the first time often struggle with the terminology. A study was therefore conducted to investigate whether knowing the meaning of an anatomical term helped students recognise the anatomical structure, and whether identifying an associated E...

We explored the performance of structure-based computational analysis in four neurodegenerative conditions [Ataxia (AT, n = 16), Huntington's Disease (HD, n = 52), Alzheimer's Disease (AD, n = 66), and Primary Progressive Aphasia (PPA, n = 50)], all characterized by brain atrophy. The independent variables were the volumes of 283 anatomical areas, derived from automated segmentation of T1-high ...
