This paper presents a morphology-based method for detecting license plates from cluttered images. The proposed system consists of three major components. At the first, is to extract important contrast features as guides search desired plates. feature robust lighting changes and invariant several transformations like scaling, translation, skewing. Then, recovery algorithm applied reconstructing plate if fragmented into parts. last step do verification. morphology based can significantly...

Monitoring heart rates using conventional electrocardiogram equipment requires patients to wear adhesive gel patches or chest straps that can cause skin irritation and discomfort. Commercially available pulse oximetry sensors attach the fingertips earlobes also inconvenience for spring-loaded clips be painful use. Therefore, a novel robust face-based rate monitoring technique is proposed allow evaluation of variation without physical contact with patient. Face reflectance first decomposed...

Background Obesity is a major health concern that raises the risk of chronic illnesses such as heart disease, diabetes, and metabolic disorders. Traditional workouts running or walking can be difficult for overweight individuals due to heavy impact on joints, which causes discomfort possibility injury. Water-based exercises offer low-impact alternative people may find more tolerable. There minimal research specific effects structured water aerobic exercise markers in young obese women,...

This paper proposes a hybrid motion-based video retrieval system to retrieve desired videos from databases through trajectory matching. The method includes sketch-based scheme and string-based one analyze index with more syntactic meanings. First of all, this uses sampling technique extract set control points each as features. Then, the curve fitting interpolate some missed data in points. visual distance between any two trajectories can be directly measured by comparing their position data....

The aim of this study was to analyze the variations acute load (AL), acute: chronic workload ratio (ACWR), training monotony (TM), and strain (TS) accelerometry-based GPS measures in players who started three matches (S3M), two (S2M), one match (S1M) during congested weeks. Nineteen elite professional male from a Portuguese team (age: 26.5 ± 4.3 years) were monitored daily using global positioning systems (GPSs) over full season (45 weeks). Accelerometry-derived high metabolic distance...

Verbal encouragement (VE) can be used by physical education (PE) practitioners for boosting motivation during exercise engagement. The purpose of this study was to investigate the effects VE on psychophysiological aspects and performance in a PE context.

The aim of this study was to examine ultra-short-term and short-term heart rate variability (HRV) in under-20 (U-20) national futsal players during pre-tournament training camps an official tournament. Fourteen male U-20 (age = 18.07 ± 0.73 yrs; height 169.57 8.40 cm; body weight 64.51 12.19 kg; fat 12.42% 3.18%) were recruited participate study.

Smartphone apps for heart rate variability (HRV) measurement have been extensively developed in the last decade. However, ultra-short-term HRV recordings taken by wearable devices not examined.The aims of this study were following: (1) to compare validity and reliability short-term time-domain frequency-domain variables a novel smartphone app, Pulse Express Pro (PEP), (2) determine agreement assessments between an electrocardiogram (ECG) PEP.In total, 60 healthy adults recruited participate...

Background. Physical conditions are recognized to be optimal after the pre-season (PS) phase in professional sports. Given that blood measures may also reveal variations, which turn, present associations with fitness changes. Objective. The aim of this study is test changes markers and physical outcomes at beginning following PS phase. Additionally, we aimed analyze training adaptations between measures. Methodology. 25 male soccer players (28.1 ± 4.6 years old, 2.0 7.8 kg, 176.7 4.9 cm)...

Posterior acoustic shadowing (PAS) can bias breast tumor segmentation and classification in ultrasound images. In this paper, half-contour features are proposed to classify benign malignant tumors with PAS, considering the fact that upper half of contour is less affected by PAS. Adaptive thresholding disk expansion employed detect contours. Based on detected full contour, extracted. For classification, six quantitative feature parameters analyzed for both contours contours, including...

Arterial pulse wave velocity (PWV) is recognized as a convenient method to assess peripheral vascular stiffness. This study explored the clinical characteristics of hand PWV (hPWV) and transit time (hPTT) in healthy adults (sixty males = 42.4 ± 13.9 yrs; sixty-four females 42.8 yrs) voluntarily participated this study.

A color selection method that considers subjective principles is becoming more and necessary in a computer-based management system. However, one from an engineering perspective has received limited attention. Previously, we developed approach to measure the degree of harmony by similarity pleasure-related function, CLD (color linguistic distribution), RHD (reference distribution) on one-dimensional image scale EXCITING–CALM. Following this approach, new system presented article modulating...
