This article proposes offline language-free writer identification based on speeded-up robust features (SURF), goes through training, enrollment, and identification stages. In all stages, an isotropic Box filter is first used to segment the handwritten text image into word regions (WRs). Then, the SURF descriptors (SUDs) of word region and the corresponding scales and orientations (SOs) are extr...

As multimedia data sharing increases, security in mobile devices and its mechanism can be seen as critical. Biometrics combines the physiological behavioral qualities of an individual to validate their character real-time. Humans incorporate attributes like a fingerprint, face, iris, palm print, finger knuckle Deoxyribonucleic Acid (DNA), walk, voice, mark, or keystroke. The main goal this pape...

In this paper,a fast and efficient video stabilization method based on speeded-up robust features (SURF) is presented .We adopted speeded-up robust features as feature descriptor,which are extracted and tracked in each frame .After that, we further refined the matching features through RANSAC, estimating the motion parameters through least squares method and computed the integrated motion. Expe...

In surf fiction it is common for wave-riders to be tested. The test of self – battling against nature, others, and one’s own capabilities a popular thematic pathway discovery, growth freedom, as manifested regularly in surf-related since its beginnings 1849. This paper looks at the first three novels that featured surfing Mardi Voyage Thither (Melville, 1849), Coral Island: A Tale Pacific Ocean...

Any good medical ultrasound imaging system must be able to resolve anatomical structures properly, and simultaneously provide adequate frame rate so that moving structures can be studied with ease. In a conventional imaging system these properties are related by a trade-off, but is it possible to have one and the other by applying more advanced post-processing to acquired RF data? Two new metho...

Introduction / objectives Partnership between service users and researchers is a cornerstone of the current research and development strategy for England’s National Health Service and is considered by funders as essential throughout the entire research process. To promote and facilitate public involvement in the field of HCAI research, the HCAI Research Network (RN) formed a Service User Resear...

The field of image set compression, which refers to the compression of image sets like photo albums and medical images, is becoming increasingly relevant in today’s digital world. In recent years, several schemes for image set compression have been proposed. In this paper, we propose a new SURF based image set compression scheme which uses SURF and HEVC. We also provide comparison results of ou...

Proton transfer reaction-mass spectrometry (PTR-MS) is a spectrometric technique that allows direct injection and analysis of mixtures of volatile compounds. Its coupling with data mining techniques provides a reliable and fast method for the automatic characterization of agroindustrial p w d t d c ©

Briefly, what approach or combination of approaches did you test in each of your submitted runs? • all runs: video decoding using ffmpeg library, sampling every 25th frame. • F_X_NO_TNO_1: standard SURF keypoint detection, bag-of-words using 4096 prototypes from videos, indexing and querying using Lemur. • F_X_NO_TNO_2: standard SURF keypoint detection, bag-of-words using 256 prototypes from qu...

In vision-based autonomous landing system of UAV (Unmanned Aerial Vehicle), the efficiency of object detection and tracking will directly affect the control system. An improved algorithm of SURF (Speed Up Robust Features) will resolve the problem which is inefficiency of the SURF algorithm in the autonomous landing system of UAV. The improved algorithm is composed of three steps: first, detect ...
