Il senso del mare. Fenomenologia del surf sulla Gold Coast australiana

Antropologia, 2021
A partire da una concezione delle “culture sportive” come prodotti storici e culturali e a loro volta come ambiti di produzione di cultura, analizzo da un punto di vista etnografico come la pratica del surf sulla Gold Coast australiana veicoli non solo ...

Note: An object detection method for active camera [PDF]

, 2013
To solve the problems caused by a changing background during object detection in active camera, this paper proposes a new method based on SURF (speeded up robust features) and data clustering. The SURF feature points of each image are extracted, and each

Nearshore oblique sand bars [PDF]

, 2003
The coupling between hydrodynamics and the evolving topography in the surf zone has been theoretically examined for oblique wave incidence. It is shown that positive feedback can lead to the initial growth of several types of rhythmic systems of sand ...

Image Segmentation and Feature Extraction Using Sift-Sad Algorithm for Disparity Map Generation

Communications, 2013
In this paper, a stereo matching algorithm based on image segments and disparity measurement using stereo images is presented. We propose the hybrid segmentation algorithm that is based on a combination of the Belief Propagation and Mean Shift algorithms

Interaction effects on almost flat surface bands in topological insulators [PDF]

, 2013
We consider ferromagnetic instabilities of two-dimensional helical Dirac fermions hosted on the surface of three-dimensional topological insulators. We investigate ways to increase the role of interactions by means of modifying the bulk properties which ...

Classification of COVID-19 Chest X-Ray Images Based on Speeded Up Robust Features and Clustering-Based Support Vector Machines

Applied Computer Systems, 2023
Due to the worldwide deficiency of medical test kits and the significant time required by radiology experts to identify the new COVID-19, it is essential to develop fast, robust, and intelligent chest X-ray (CXR) image classification system. The proposed
