Recognition of Handwritten Bangla Basic Characters and Digits using Convex Hull based Feature Set
In dealing with the problem of recognition of handwritten character patterns of varying shapes and sizes, selection of a proper feature set is important to achieve high recognition performance. The current research aims to evaluate the performance of the convex hull based feature set, i.e. 125 features in all computed over different bays attributes of the convex hull of a pattern, for effective...
متن کاملGeometric Feature Extraction for Hand Gesture Recognition
Computer applications have been spread ubiquitous due to its essential important that facilitate our daily life, gesture system is one of the most appealing applications that dependents mainly on exploiting the right features that can embody the entire gesture and give the correct meaning of that gesture. For constructing gesture recognition system a serial steps should be considered that are: ...
متن کاملConvex Hull Asymptotic Shape Evolution
The asymptotic properties of Rapidly exploring Random Tree (RRT) growth in large spaces is studied both in simulation and analysis. The main phenomenon is that the convex hull of the RRT reliably evolves into an equilateral triangle when grown in a symmetric planar region (a disk). To characterize this and related phenomena from flocking and swarming, a family of dynamical systems based on incr...
متن کاملHand Recognition Using Geometric Classifiers
Biometric recognition systems find applications in security systems with varying requirements. While finger printing and iris based systems work well for high security applications, they are not as suitable for medium and low security applications because of privacy concerns. Hand Geometry based verification systems find more acceptance because hand geometry is not considered distinctive enough...
متن کاملPartial shape matching using convex hull and Fourier descriptors
An application of Fourier descriptors and convex hull for shape analysis is presented. Convex hull is used for dividing a shape into small parts. Amplitude spectrum which is invariant to scaling, translation and choosing a starting point is obtained from the Fourier descriptors (see e.g [1-3]) and used for comparison. All calculations are performed with the author's software and some algorithms...
