ABSTRACT Objective To verify the factors associated with perception of current silhouette and body image dissatisfaction in adults obesity. Methods Cross-sectional study derived from baseline a randomized clinical trial. The image, defined by difference between ideal silhouette, were obtained scale that ranged one (smallest silhouette) to nine (largest silhouette). independent variables investi...

This paper presents a novel view independent approach on silhouette based human motion analysis for gait recognition applications. Spatio-temporal 1-D signals based on the differences between the outer of binarized silhouette of a motion object and a bounding box placed around silhouette are chosen as the basic image features called the distance vectors. The distance vectors are extracted using...

Video can be regarded as three dimensional spatio-temporal volume, in which human action is a three dimensional shape (3D shape) surrounded by the spatio-temporal silhouette surface. The type of human action depends on the shape of the silhouette surface. In this paper, we proposed a new feature called Oriented Gradient Histogram of Slide Blocks by building dense overlapping spatio-temporal sli...

Among the multiple models for 3-D shape reconstruction, Shape from silhouette (SFS) is one of the fast and simple 3D shape rendering techniques as compare to other approaches. In SFS model multiple images captured from different viewpoints in a controlled environment are used as input data at the front end to extract silhouette and are free of noises. Silhouette extraction from such well-define...

We approach the task of human silhouette extraction from color and thermal image sequences using automatic image registration. Image registration between color and thermal images is a challenging problem due to the difficulties associated with finding correspondence. However, the moving people in a static scene provide cues to address this problem. In this paper, we propose a hierarchical schem...

In this paper, we propose spatio-temporal silhouette representations, called silhouette energy image (SEI) and silhouette history image (SHI) to characterize motion and shape properties for recognition of human movements such as human actions, activities in daily life. The SEI and SHI are constructed by using the silhouette image sequence of an action. The span or difference of the end time and...

Silhouette volume intersection is one of the most popular ideas for reconstructing the 3D volume of an object from multi-viewpoint silhouette images. This paper presents a novel parallel volume intersection method based on planeto-plane homography for real-time 3D volume reconstruction using active cameras. This paper mainly focuses on the acceleration of back-projection from silhouette images ...

W e address the problem of estimating the structure and motion of a smooth curved object from its silhouettes observed over time by a trinocular imagery. W e first construct a model for the local structure along the silhouette for each frame in the temporal sequence. The local models are then integrated into a global surface description by estimating the motion between successive frames. The al...

Ghost is a real time system for estimating human body posture and detecting body parts in monochromatic imagery. It constructs a silhouette based body model to determine the location of the body parts while people are in generic postures. It combines hierarchical body pose estimation, a convex hull analysis of the silhouette, and a partial mapping from the body parts to the silhouette segments ...

OBJECTIVE To investigate the relationship between dietary patterns and self-perceived body shape silhouette and BMI in a sample of Mexican women. DESIGN A cross-sectional analysis of dietary habits from baseline data of a large cohort study (EsMaestra) conducted in 2006-2008. SETTING The state of Veracruz, Mexico. SUBJECTS Mexican teachers (n 20 330) provided information on body shape sil...
