Monocular and Binocular Visual Tracking
… windows. Accordingly, a new approach based on moment invariants was developed to select window size adaptively. This approach is based on the sudden increasing or decreasing in the first Maitra moment invariant. We applied a robust regression model to smooth the first Maitra moment invariant to …

MODEL-BASED 3-D VISION
… in this thesis. This method uses Zernike moment invariants of the silhouette of the unknown object to form a set of fuzzy-weighted quantities called fuzzy quaternions. The database of the models is generated by first creating the octree representation of the 3-D objects based on three …

New Computational Methodologies for Microstructure Quantification
… sensitive design. From this, the use of shape moment invariants is offered as solution to quantifying microstructure topology numerically using images. This offers a substantial benefit for computational time since image data is converted to numeric values. The goal of quantifying the image …

Methods for recognizing patterns in digitized line drawings
… and portions of the image line data. Hu's moment invariants [16] are used to match simple shapes and prune the search space. Information about the connectivity of patterns matched in the image is retained, allowing higher level analysis of image content. A second method for calculating a …

Investigation of New Techniques for Face detection
… Discrete Wavelet Transform (2D-DWT), geometrical moment invariants, and edge detection. It also attempts to construct a hybrid feature vector by the fusion between 2D-DCT coefficients and edge information, as well as the fusion between 2D-DWT coefficients and geometrical moments. A self organizing …

Hand gesture recognition for multimedia applications
… models and tracked using the CAMShift tracker. Moment invariants are used as a shape descriptor. A new approach utilising the Zernike Velocity Moments (ZVMs, first introduced by Shutler and Nixon [1,2]), is examined on hand gestures. Results obtained using the ZVMs as spatial-temporal descriptor …

Exploring the Stochastic Performance of Metallic Microstructures With Multi-Scale Models
Titanium-7%wt-Aluminum (Ti-7Al) has been of interest to the aerospace industry owing to its good structural and thermal properties. However, extensive research is still needed to study the structural behavior and determine the material properties of Ti-7Al. The homogenized macro-scale material …
