نویسنده
چکیده
A simple scheme is presented for modifying geometric moments to use geodesic distances. This provides a set of global shape descriptors that are invariant to bending as well as rotation, translation and scale.

Zernike velocity moments for sequence-based description of moving features
The increasing interest in processing sequences of images motivates development of techniques for sequence-based object analysis and description. Accordingly, new velocity moments have been developed to allow a statistical description of both shape and associated motion through an image sequence. Through a generic framework motion information is determined using the established centralised mome...
متن کاملA Shape Descriptor Using Complex Moment Invariants
This paper proposes a robust and effective shape feature, which is based on a set of orthogonal complex moments of images known as Zernike moments. Zernike moment phase is usually not used in image description since its sensitive to image rotations. However, phase captures important image information, which is revealed by our numerical analysis of image reconstruction. We therefore propose com...
متن کاملAutomated Color Logo Recognition System based on Shape and Color Features
This paper proposes an automated system for rotation and scale invariant color logo recognition. Colored logo images are recognized using one shape feature namely Moments Invariant and a color feature namely Color Moments. Shape of the logo is modeled using the first two central normalized Hu's invariant moments while color is modeled using the mean, standard deviation, skewness and kurtos...
متن کاملPerceptually-driven moment thresholds for shape description in image databases
Over the past five years, a huge influx of visual data has arisen within the realm of computing. Consequently, it is evident that a means of automatically indexing this visual information on the basis of content is required. This paper discusses a component of an image retrieval system with the ability to automatically locate and classify an image’s constituent shapes. The images employed are p...
متن کاملBending moments and types of failure of zirconia and titanium abutments with internal implant-abutment connections: a laboratory study.
PURPOSE The aim of this study was to examine the bending moments and fracture patterns of different zirconia abutments with internal implant-abutment connections after static loading and to compare their bending moments to those of internally connected titanium abutments. MATERIALS AND METHODS Three types of customized zirconia abutments (Straumann CARES abutments/Straumann BL implants [T1], ...
