Abstract The aim of this study was to verify the effect pinch size on skinfold thickness measurement and consequent interference in estimation classification body adiposity components. Cross-sectional quantitative carried out with a sample 29 subjects recruited from university city Fortaleza, Ceará, Brazil. Four steps were performed at each site eight chosen skinfolds. first step subjective-lan...

Volume-based registration (VBR) is the predominant method used in human neuroimaging to compensate for individual variability. However, surface-based registration (SBR) techniques have an inherent advantage over VBR because they respect the topology of the convoluted cortical sheet. There is evidence that existing SBR methods indeed confer a registration advantage over affine VBR. Landmark-SBR ...

Cascade regression framework has been shown to be effective for facial landmark detection. It starts from an initial face shape and gradually predicts the face shape update from the local appearance features to generate the facial landmark locations in the next iteration until convergence. In this paper, we improve upon the cascade regression framework and propose the Constrained Joint Cascade ...

This paper proposes and analyzes modifications to the Landmark routing system that make it better suited to large ad hoc wireless networks. Most existing ad hoc routing algorithms scale badly in the sense that they generate protocol overhead whose per-node cost grows linearly with the total number of nodes. The Landmark routing protocol solves this problem by use of hierarchical addresses that ...

This paper investigates the function and formation of spatial language involving landmarks. We argue for two points. First, landmarks have an important function in spatial language. Agents that can use different landmarks and express their choice perform better than agents who cannot. Second, the use of landmarks has a positive effect on evolving systems of spatial relations. Agents that have t...

We propose the novel approach of dynamic affine-invariant shape-appearance model (Aff-SAM) and employ it for handshape classification and sign recognition in sign language (SL) videos. AffSAM offers a compact and descriptive representation of hand configurations as well as regularized model-fitting, assisting hand tracking and extracting handshape features. We construct SA images representing t...

In this paper, facial expressions of the three Turkish presidential candidates Demirtas, Erdogan and Ihsanoglu (in alphabetical order) are analyzed during the publicity speeches featured at TRT (Turkish Radio and Television) on 03.08.2014. FaceReader is used for the analysis where 3D modeling of the face is achieved using the active appearance models (AAM). Over 500 landmark points are tracked ...

We present an algorithm that efficiently tracks a predefined set of landmark points in a time sequence of images. The algorithm iteratively optimizes the correspondences between the point measurements in the images, while allowing for spurious and missing point measurements. This trajectory based approach hypothesizes missing points by interpolation. Spurious measurements are either left out be...
