    Full text link
    Disguised face identification (DFI) is an extremely challenging problem due to the numerous variations that can be introduced using different disguises. This paper introduces a deep learning framework to first detect 14 facial key-points which are then utilized to perform disguised face identification. Since the training of deep learning architectures relies on large annotated datasets, two annotated facial key-points datasets are introduced. The effectiveness of the facial keypoint detection framework is presented for each keypoint. The superiority of the key-point detection framework is also demonstrated by a comparison with other deep networks. The effectiveness of classification performance is also demonstrated by comparison with the state-of-the-art face disguise classification methods.Comment: To Appear in the IEEE International Conference on Computer Vision Workshops (ICCVW) 201

    Review on ‘Swastya’ - Principles of Charaka Samhita as explained in Dinacharya and Rutucharya

    Ayurveda is explained by Acharya Caraka as science of life. The primary motive of Ayurveda is maintenance of positive health of an individual and treatment of the diseased; in order to attain four Purusharthas, which is possible only if a person is healthy. Ultimately the benefit of studying the Caraka Samhita is to achieve Dhatu Saamya (equilibrium of body components). The concept of Swastya is explained in every Sthana of Caraka Samhita which explains the significance or existence of concepts of personal health and well-being. Through concepts of promotion of health and personal well-being exceptionally said, Charaka Samhita thus may be considered as textbook of tagline, adding life to years and not merely years to life

    Machine-to-machine (M2M) communication devices communicate and exchange information with each other in an independent manner to perform necessary tasks. The machine communicates with another machine over a wireless network. Wireless communication opens up the environment to huge vulnerabilities, making it very easy for hackers to gain access to sensitive information and carry out malicious actions. This paper proposes an M2M communication system through the internet in Tele-Robotics and provides network performance security. Tele-robotic systems are designed for surgery, treatment and diagnostics to be conducted across short or long distances while utilizing wireless communication networks. The systems also provide a low delay and secure communication system for the tele-robotics community and data security. The system can perform tasks autonomously and intelligently, minimizing the burden on medical staff and improving the quality and system performance of patient care. In the medical field, surgeons and patients are located at different places and connected through public networks. So the design of a medical sensor node network with LEACH protocol for secure and reliable communication ensures through the attack and without attack performance. Finally, the simulation results show low delay and reliable secure network transmission

    Background: Allergic eye diseases are the commonest causes of ocular morbidity worldwide. To choose the best therapy in allergic conjunctivitis, understanding of underlying mechanisms implicated in triggering the allergy is very important. Olopatadine with a wide spectrum has proven to be very effective in allergic conjunctivitis. The objective of the study was to compare the efficacy and safety of ophthalmic solutions of olopatadine 0.2% once daily, olopatadine 0.1% twice daily and sodium cromoglycate 2% four times daily in allergic conjunctivitis for 3 weeks.Methods: This was a prospective, single centre study enrolling 304 patients with allergic conjunctivitis attending ophthalmology clinics. Subjects were assessed for ocular signs and symptoms at 3 visits-baseline, week 2, week 3. The change from baseline in the mean scores of itching and redness at 3 weeks was primary outcome variable.Results: The reduction in signs and symptoms were statistically significant in all the three groups (p <0.001). Both the olopatadine receiving groups were better than sodium cromoglycate receiving group in reducing ocular signs and symptoms by pairwise comparison by wilcoxon signed rank test.Conclusions: Olopatadine ophthalmic solution is better than sodium cromoglycate ophthalmic solution in reducing the ocular signs and symptoms in allergic conjunctivitis

    Face acknowledgment is a testing issue because of variety in demeanor, posture, brightening and maturing and so on. The presented paper basically deals with the working of face recognition system using Principal Component analysis (PCA). PCA is a quantifiable approach used for diminishing the quantity of factors in confront acknowledgement. In PCA, each photo in the planning set is considered as an immediate mix of weighted eigenvectors called eigenfaces. These eigenvectors are obtained from covariance lattice of an arrangement picture set. The weights are found in the way of picking a game plan of most noteworthy Eigenfaces. Affirmation is done by anticipating a test picture onto the subspace crossed by the eigenfaces and after that course of action is done by assessing the minimum Euclidean division

    At the KIT electron storage ring KARA (Karlsruhe Research Accellerator) an electro-optical (EO) near-field monitor is in operation performing single-shot, turn-by-turn measurements of the longitudinal bunch profile using electro-optical spectral decoding (EOSD). In context of the Future Circular Collider Innovation Study (FCCIS), a similar setup is investigated with the aim to monitor the longitudinal bunch profile of each bunch for dedicated top-up injection at the future electron-positron collider FCC-ee. This contribution presents the status of a monitor design adapted to cope with the high-current and high-energy lepton beams foreseen at FCC-ee

    At the KIT storage ring KARA (Karlsruhe Research Accelerator), a far-field electro-optical (EO) experimental setup to measure the temporal profile of the coherent synchrotron radiation (CSR) is implemented. Here, the EOSD (electro-optical spectral decoding) technique will be used to obtain single-shot measurements of the temporal CSR profile in the terahertz frequency domain. To keep the crucial high signal-to-noise ratio a setup based on balanced detection is under commission. Therefore, simulations are performed for an optimized beam path and the setup is characterized. In this contribution, the upgraded setup and first measurements are presented

    KARA, the Karlsruhe Research Accelerator, can be operated in different modes, including a short-bunch mode. During this mode, where the dispersion is stretched in order to reduce the momentum-compaction factor, micro-bunching instability can occur. At KARA, several measurement setups and techniques are used to investigate this instability further with the long-term perspective to suppress and control it. In this contribution, we give an overview about the different setups and the results achieved during the past years

    Electro-Optical Diagnostics at KARA and FLUTE – Results and Prospects

    Get PDF
    Electro-optical (EO) methods are nowadays well-proven diagnostic tools, which are utilized to detect THz fields in countless experiments. The world’s first near-field EO sampling monitor at an electron storage ring was developed and installed at the KIT storage ring KARA (Karlsruhe Research Accelerator) and optimized to detect longitudinal bunch profiles. This experiment with other diagnostic techniques builds a distributed, synchronized sensor network to gain comprehensive data about the phase-space of electron bunches as well as the produced coherent synchrotron radiation (CSR). These measurements facilitate studies of physical conditions to provide, at the end, intense and stable CSR in the THz range. At KIT, we also operate FLUTE (Ferninfrarot Linac- und Test-Experiment), a new compact versatile linear accelerator as a test facility for novel techniques and diagnostics. There, EO diagnostics will be implemented to open up possibilities to evaluate and compare new techniques for longitudinal bunch diagnostics. In this contribution, we will give an overview of results achieved, the current status of the EO diagnostic setups at KARA and FLUTE and discuss future prospects
