A feature detector and a feature descriptor are presented, which are applicable to 3D range data. The feature detector is used to identify locations in the range data at which the feature descriptor is applied. The feature descriptor, or feature transform, calculates a signature for each identified location on the basis of local shape information. The approach used in both the feature detector ...

© 2013 Woo-han Yun et al. 1021 http://dx.doi.org/10.4218/etrij.13.2013.0054 Automatic facial expression recognition is a widely studied problem in computer vision and human-robot interaction. There has been a range of studies for representing facial descriptors for facial expression recognition. Some prominent descriptors were presented in the first facial expression recognition and analysis ch...

This paper illustrates a systematical surface topography measurement and evaluation method based on 3D optical system. Firstly, the point cloud data of workpiece are extracted by use structured light system, STEP file design model is converted into data. Secondly, local (LMPC) digital (DMPC) registered multivariate descriptor registration scheme proposed in this study. Thirdly, shapes from appl...

Abstract Most of the existing local descriptors unable to perform well in front noise and blur variations. Additionally there are very less persist literature which invariant. To remedy this challenge proposed work launch novel descriptor under changes so-called Noise Blur Invariant Local Descriptor (NABILD). With respect two artificial noises i.e. Gaussian White (GWN) Salt & Pepper (SPN) w...

Digital image processing techniques are useful in abnormality detection in mammogram images. Recently, texture based image segmentation of mammogram images has become popular due to its better precision and accuracy. Local Binary Pattern has been a recently proposed texture descriptor which attracted the research community rigorously towards texture based analysis of digital images. Many textur...

Local Binary Patterns (LBP) is a non-parametric descriptor whose purpose to effectively summarize local image configurations. It has generated increasing interest in many aspects including facial analysis, vision detection, expression demographic classification, etc. recent years and proven useful various applications. This paper presents binary pattern based face recognition technology using V...
