[1] Turbulence in the surf zone, the shallow region adjacent to the shoreline, has a key role in beach erosion, fertilization, dispersal, and larval settlement of marine invertebrates, and microbial contamination dilution in beach waters. Breakingwave generated (the dominant source) surf zone turbulence is understood poorly. A new surf zone turbulent dissipation rate scaling is derived, that co...

The visual analysis of foods on social media by using food recognition algorithm provides valuable insight from the health, cultural and marketing. Food offers a means to automatically recognise as well useful information such calories nutritional estimation image processing machine learning technique. interest points in can be detected effectively Maximally Stable Extremal Region (MSER). As MS...

Ejection phase indices such as mean velocity of circumferential fiber shortening (V-cf), ejection fraction (EF), and mean normalized systolic ejection rate (MSER) are thought to reflect the level of left ventricular (LV) inotropic state. Although known to be influenced by changes in afterload, their response to altered preload is less certain. This question was examined in ten normal subjects s...

In this paper, we present a novel family of multiscale local feature descrip1 tors, a theoretically and intuitively well justified variant of SURF which is 2 straightforward to implement but which nevertheless is capable of demon3 strably better performance with comparable computational cost. Our family 4 of descriptors, called Gauge-SURF (G-SURF), are based on second-order 5 multiscale gauge d...

Cattle identification has been a serious problem for breeding association. The need of a robust identification method is a must. The previous identification means have not been satisfactory. The biometric marking has been investigated to be a permanent marking of the individual. Muzzle pattern or nose print has the same characteristic with the human fingerprint which is the most popular biometr...

SURF is one of the most robust local invariant feature descriptors. SURF is implemented mainly for gray images. However, color presents important information in the object description and matching tasks as it clearly in the human vision system. Many objects can be unmatched if their color contents are ignored. To overcome this drawback this paper proposed a method CSURF (Color SURF) that combin...

In this paper, we propose SURF feature based approach for mobile robot navigation. In this approach, we capture environmental images by using omni-directional camera and extract features of these images by using SURF. We treat these features as landmarks and estimate robot self-location and direction of motion. SURF features are invariant under scale change and rotation and robust under image n...

Loss-of-function mutations of the SURF-1 gene have been associated with Leigh syndrome with cytochrome c oxidase (COX) deficiency. Mature Surf-1 protein (Surf-1p) is a 30 kDa hydrophobic polypeptide whose function is still unknown. Using antibodies against a recombinant, hemagglutinin-tagged Surf-1p, we have demonstrated that this protein is imported into mitochondria as a larger precursor, whi...

Ejection phase indices of left ventricular myocardial performance, mean velocity of circumferential fiber shortening (mVcf), mean systolic ejection rate (mSER), and ejection fraction (EF) were determined in 248 pediatric patients, utilizing left ventricular projections of cineangiograms. Heart rate significantly affected mVcf and mSER values in the normal group (r=0.74, 0.79, respectively). A m...
