Human Motion Segmentation using Active Shape Models

Speaker-specific articulatory assessment and measurements during Portuguese spe...

The development of two and three-dimensional magnetic resonance imaging (MRI) opened new options for a better understanding of speech production; in particular, for the articulation process, comparing with other imaging techniques, such as x-rays. Several MRI studies have been carried out considering different languages, but concerning European Portuguese the available information is far from being completely a...

Towards the automatic study of the vocal tract from magnetic resonance images

Over the last few decades, researchers have been investigating the mechanisms involved in speech production. Image analysis can be a valuable aid in the understanding of the morphology of the vocal tract. The application of magnetic resonance imaging to study these mechanisms has been proven to be reliable and safe. We have applied deformable models in magnetic resonance images in order to conduct an automatic ...

Segmentation Methods for Human Motion Analysis from Image Sequences

Modelling and Segmentation of the Vocal Track during Speech Production by using...

Using Statistical Deformable Models to Reconstruct Vocal Tract Shape from Magne...

The mechanisms involved in speech production are complex and have thus been subject to growing attention by the scientific community. Magnetic Resonance Imaging (MRI) has been proven to be a powerful means in the understanding of the morphology of the vocal tract. Over the last few years, statistical deformable models have been successfully used to identify and characterize bones and organs in medical images an...

Image Segmentation for Human Motion Analysis: methods and applications

Human Motion Analysis: methodologies and applications

The study of motion is one of the most interesting areas in Computational Vision, particularly the human motion research. During these last decades several works were presented regarding this subject. Human motion analysis is complex, non-linear and time variant and its tracking can be done using Computational Vision through, for example, human modeling. In order to make human motion analysis more computational...

Methods to automatically build Point Distribution Models for objects like hand ...

In this work we developed methods to automatically extract significant points of objects like hand palms and faces represented in images that can be used to build Point Distribution Models automatically. These models are further used to segment the modelled objects in new images, through the use of Active Shape Models or Active Appearance Models. These models showed to be efficient in the segmentation of object...
