Comparison of Body Shape Descriptors for Biometric Recognition using MMW Images
"... Abstract—The use of Millimetre wave images has been proposed recently in the biometric field to overcome certain limitations when using images acquired at visible frequencies. In this paper, several body shape-based techniques were applied to model the silhouette of images of people acquired at 94 G ..."

Real-time human pose recognition in parts from single depth images
- IN CVPR
, 2011
"... We propose a new method to quickly and accurately predict 3D positions of body joints from a single depth image, using no temporal information. We take an object recognition approach, designing an intermediate body parts representation that maps the difficult pose estimation problem into a simpler p ..."

An affine invariant interest point detector
- In Proceedings of the 7th European Conference on Computer Vision
, 2002
"... Abstract. This paper presents a novel approach for detecting affine invariant interest points. Our method can deal with significant affine transformations including large scale changes. Such transformations introduce significant changes in the point location as well as in the scale and the shape of ..."

to affine invariant points. For matching and recognition, the image is characterized by a set of affine invariant points; the affine transformation associated with each point allows the computation of an affine invariant descriptor which is also invariant to affine illumination changes. A quantitative
Body shape-based biometric recognition using millimeter wave images

An Experimental Comparison of Autoregressive and Fourier-based Descriptors in 2-D Shape Classification
, 1995
"... An experimental comparison of shape classification methods based on autoregressive modeling and Fourier descriptors of closed contours is carried out. The performance is evaluated using two independent sets of data: images of letters and airplanes. Silhouette contours are extracted from non-occluded ..."

Distance sets for shape filters and shape recognition
- IEEE TRANS. IMAGE PROCESSING
, 2003
"... We introduce a novel rich local descriptor of an image point, we call the (labeled) distance set, which is determined by the spatial arrangement of image features around that point. We describe a two-dimensional (2-D) visual object by the set of (labeled) distance sets associated with the feature p ..."

, and shape matching. The use of the shape filter is illustrated on printed and handwritten character recognition and detection of traffic signs in complex scenes. The shape comparison procedure is illustrated on handwritten character classification, COIL-20 database object recognition and MPEG-7 silhouette
3D Face Recognition by Matching Shape Descriptors Abstract
"... Face is an important biometric for the identification and authentication of individuals. 2D face recognition techniques have been investigated for a long time. However, 3D face recognition is a relatively niche area of research. We propose a novel algorithm for 3D face recognition. A gallery of 3D f ..."

faces is generated and saved along with their tensor representation (shape descriptors) during an offline phase. During online recognition, a tensor is generated for the range image of a probe face and matched with the tensors of gallery faces using a weighted linear correlation coefficient
Personal recognition using hand shape and texture
- IEEE Trans. Image Process
, 2006
"... Abstract—This paper proposes a new bimodal biometric system using feature-level fusion of hand shape and palm texture. The proposed combination is of significance since both the palmprint and hand-shape images are proposed to be extracted from the single hand image acquired from a digital camera. Se ..."

"... Automatically recovering human poses from visual input is useful but challenging due to variations in image space and the high dimensionality of the pose space. In this paper, we assume that a human silhouette can be extracted from monocular visual input. We compare three shape descriptors that are ..."
