Knee pain is pain in or around the knee. The knee joint consists of an articulation between four bones: the femur, tibia, fibula and patella. There are four compartments to the knee. This crosssectional study was conducted among outdoor patients presenting in different hospitals. Name, age, gender, presence or absence of knee joint pain, treatment modalities were noted on a predefined proforma. All the data was entered and analyzed with SPSS Ver. 23.0. There were 100 patients included in this

3DAirSig: A Framework for Enabling In-Air Signatures Using a Multi-Modal Depth Sensor

Jameel Malik, Ahmed Elhayek, Sheraz Ahmed, Faisal Shafait, Muhammad Imran Malik, Didier Stricker
2018 Sensors  
In-air signature is a new modality which is essential for user authentication and access control in noncontact mode and has been actively studied in recent years. However, it has been treated as a conventional online signature, which is essentially a 2D spatial representation. Notably, this modality bears a lot more potential due to an important hidden depth feature. Existing methods for in-air signature verification neither capture this unique depth feature explicitly nor fully explore its

Inspired by the great progress in deep-learning-based hand pose estimation, we propose a real-time in-air signature acquisition method which estimates hand joint positions in 3D using a single depth image. The predicted 3D position of fingertip is recorded for each frame. We present four different implementations of a verification module, which are based on the extracted depth and spatial features. An ablation study was performed to explore the impact of the depth feature in particular. For matching, we employed the most commonly used multidimensional dynamic time warping (MD-DTW) algorithm. We created a new database which contains 600 signatures recorded from 15 different subjects. Extensive evaluations were performed on our database. Our method, called 3DAirSig, achieved an equal error rate (EER) of 0 . 46 %. Experiments showed that depth itself is an important feature, which is sufficient for in-air signature verification. The dataset will be publicly available (

Simultaneous Hand Pose and Skeleton Bone-Lengths Estimation from a Single Depth Image [article]

Jameel Malik, Ahmed Elhayek, Didier Stricker
2017 arXiv   pre-print
Articulated hand pose estimation is a challenging task for human-computer interaction. The state-of-the-art hand pose estimation algorithms work only with one or a few subjects for which they have been calibrated or trained. Particularly, the hybrid methods based on learning followed by model fitting or model based deep learning do not explicitly consider varying hand shapes and sizes. In this work, we introduce a novel hybrid algorithm for estimating the 3D hand pose as well as bone-lengths of

The proposed CNN architecture learns hand pose parameters and scale parameters associated with the bone-lengths simultaneously. Subsequently, a new hybrid forward kinematics layer employs both parameters to estimate 3D joint positions of the hand. For end-to-end training, we combine three public datasets NYU, ICVL and MSRA-2015 in one unified format to achieve large variation in hand shapes and sizes. Among hybrid methods, our method shows improved accuracy over the state-of-the-art on the combined dataset and the ICVL dataset that contain multiple subjects. Also, our algorithm is demonstrated to work well with unseen images.

A case of 65-year-old male is reported who presented with myalgias, headache, and fever. He subsequently developed myocarditis and was diagnosed to have anaplasmosis on peripheral blood smear. He was treated with doxycycline for 30 days. A coronary angiogram done after recovery showed normal epicardial arteries. The case illustrates the importance of a careful examination of the peripheral smear, with a high index of clinical suspicion, which led to prompt treatment and complete recovery of the

Structure from Articulated Motion: Accurate and Stable Monocular 3D Reconstruction without Training Data

2019 Sensors  
Recovery of articulated 3D structure from 2D observations is a challenging computer vision problem with many applications. Current learning-based approaches achieve state-of-the-art accuracy on public benchmarks but are restricted to specific types of objects and motions covered by the training datasets. Model-based approaches do not rely on training data but show lower accuracy on these datasets. In this paper, we introduce a model-based method called Structure from Articulated Motion (SfAM),

At the same time, it performs on par with learning-based state-of-the-art approaches on public benchmarks and outperforms previous non-rigid structure from motion (NRSfM) methods. SfAM is built upon a general-purpose NRSfM technique while integrating a soft spatio-temporal constraint on the bone lengths. We use alternating optimization strategy to recover optimal geometry (i.e., bone proportions) together with 3D joint positions by enforcing the bone lengths consistency over a series of frames. SfAM is highly robust to noisy 2D annotations, generalizes to arbitrary objects and does not rely on training data, which is shown in extensive experiments on public benchmarks and real video sequences. We believe that it brings a new perspective on the domain of monocular 3D recovery of articulated structures, including human motion capture.

There was a significant association between the child's age (P=0.000), gender (P=0.040), and father's education (P=0.096) and nocturnal enuresis. The parents' and siblings' family history, hospital admission, blood grouping, suffering from diabetes, and UTI also has a significant association with the prevalence of nocturnal enuresis (P=0.032), (P=0.000), (P=0.024), (P=0.004), (P=0.000), and (P=0.006), respectively. Conclusion: We demonstrated a high prevalence of nocturnal enuresis among young Saudi children. Family history was significantly associated with the enuresis prevalence. High prevalence of diurnal enuresis and which caused social shame to most of the participants. Children who were admitted to hospital after delivery, born with obstructed, and those suffered from diabetes and UTI were found to have the highest prevalence of enuresis.

For many users, social media increases the variety of information and ensure its accessibility across different platforms.

In addition, the uncontrolled influx of social media in different parts of the world favors phenomena such as fake news and social bots. These threaten the exchange of views sought by mutual understanding and sincerity that democratic societies need. Motivated by these observations, this article aims to paint a realistic picture of the impact of social media. To do so, we discuss the recent developments and social changes and provide analysis of the global impact of the connected audience. Next, we shed light on some of the opinion formulation procedures and its key enablers. Finally, we present an explanatory discussion on the Facebook algorithms and provide two case studies in the wake of recent global events.
