In this paper, Harris Corner Detector is proposed as a corner detection technique to extract palmprint features in the form of corners. Here, hamming distance similarity measurement using sliding window method is used as a feature matching method for the corners detected. The aim of using hamming distance method for corner matching is the non-dependency of the method with the number of corners ...

Uniformity distribution of the corner rounding radius of curvature is investigated using reflectanceand transmittancebased optical scatterometry. Arrays of square contact holes are measured at multiple locations on an ACI photomask using a broadband spectrophotometer capable of collecting polarized reflectance (Rs and Rp) and polarized transmittance (Ts and Tp) spectra in 190 – 1000 nm waveleng...

The concept of radius of generalization was introduced in CC3 and thus this neural network overcame the generalization problem that plagued the earlier CC2 network. The Hamming distance was used for classification between binary vectors, i.e. any test vector whose Hamming distance from a training vector is smaller than the radius of generalization of the network is classified in the same output...

This paper presents a robust algorithm to extract eye features, including pupil center and radius, eye corners and eyelid contours, from frontal face images. These features are very useful cues for applications like face recognition, facial expression recognition and 3D face modeling from 2D images. With the assumption that the rough eye window is known, the proposed method integrates color inf...

Complex structures manufactured using low-pressure vacuum bag-only (VBO) prepreg processing are more susceptible to defects than flat laminates due to complex compaction conditions present at sharp corners. Consequently, effective defect mitigation strategies are required to produce structural parts. In this study, we investigated the relationships between laminate properties, processing condit...

The p-norm often used in stress constrained topology optimisation supposedly mimics a delta function and it is thus characterised by a small length scale, and the same should apply for the solid-void transition. We propose to resolve these features using anisotropic mesh adaptation. We use the method of moving asymptotes with interpolation of sensitivities, asymptotes and design variables betwe...
