    Automated Video Generation of Moving Digits from Text Using Deep Deconvolutional Generative Adversarial Network

    Anwar Ullah1, Xinguo Yu1,*, Muhammad Numan2

    CMC-Computers, Materials & Continua, Vol.77, No.2, pp. 2359-2383, 2023, DOI:10.32604/cmc.2023.041219

    Abstract Generating realistic and synthetic video from text is a highly challenging task due to the multitude of issues involved, including digit deformation, noise interference between frames, blurred output, and the need for temporal coherence across frames. In this paper, we propose a novel approach for generating coherent videos of moving digits from textual input using a Deep Deconvolutional Generative Adversarial Network (DD-GAN). The DD-GAN comprises a Deep Deconvolutional Neural Network (DDNN) as a Generator (G) and a modified Deep Convolutional Neural Network (DCNN) as a Discriminator (D) to ensure temporal coherence between adjacent frames. The proposed research involves several steps.… More >

    Coherence Based Sufficient Condition for Support Recovery Using Generalized Orthogonal Matching Pursuit

    Aravindan Madhavan1,*, Yamuna Govindarajan1, Neelakandan Rajamohan2

    Computer Systems Science and Engineering, Vol.45, No.2, pp. 2049-2058, 2023, DOI:10.32604/csse.2023.031566

    Abstract In an underdetermined system, compressive sensing can be used to recover the support vector. Greedy algorithms will recover the support vector indices in an iterative manner. Generalized Orthogonal Matching Pursuit (GOMP) is the generalized form of the Orthogonal Matching Pursuit (OMP) algorithm where a number of indices selected per iteration will be greater than or equal to 1. To recover the support vector of unknown signal ‘x’ from the compressed measurements, the restricted isometric property should be satisfied as a sufficient condition. Finding the restricted isometric constant is a non-deterministic polynomial-time hardness problem due to that the coherence of the… More >

    Jia Qin1,2,3,4,5, Lin An1,2,3,4,5,*

    Molecular & Cellular Biomechanics, Vol.19, No.3, pp. 151-157, 2022, DOI:10.32604/mcb.2022.018578

    Abstract Myopia is a common ophthalmic deficiency. The structure and function of choroid layer is assumed to be associated with myopia. In this study, a laboratory developed spectral domain optical coherence tomography scanning system is used to image human eyes. The axial resolution of the system is about 7 μm, and the acquisition rate is 100 kHz. Firstly, a cross-sectional image was acquired by averaging 100 images from imaging posterior segment of each eye. The choroid thickness was measured by 11 discrete points. The average thickness of normal human eyes was (0.296 ± 0.126) mm, whereas the average choroid thickness of… More >

    International Journal of Mental Health Promotion, Vol.24, No.1, pp. 115-127, 2022, DOI:10.32604/ijmhp.2022.017859

    Abstract The theoretical basis of the paper is Aron Antonovsky’s salutogenetic model of health, which is based on the salutogenic orientation and the sense of coherence understood as the central concept and the most important resource. The primary aim of the study is to determine the strength of the sense of family coherence in parents of optimally developing children and in parents of suboptimally developing children and their correlation with: family satisfaction and family orientation to crisis situations. The study was done using parents (N = 394) sampled from the population of the Republic of Serbia. Questionnaire for Obtaining Basic Data,… More >

    Adaptive Virtual Source Imaging Using the Sequence Intensity Factor: Simulation and Experimental Study

    Chichao Zheng, Yazhong Wang, Yadan Wang*, Qing He, Hu Peng

    CMES-Computer Modeling in Engineering & Sciences, Vol.130, No.1, pp. 397-413, 2022, DOI:10.32604/cmes.2022.016308

    Abstract Virtual source (VS) imaging has been proposed to improve image resolution in medical ultrasound imaging. However, VS obtains a limited contrast due to the non-adaptive delay-and-sum (DAS) beamforming. To improve the image contrast and provide an enhanced resolution, adaptive weighting algorithms were applied in VS imaging. In this paper, we proposed an adjustable generalized coherence factor (aGCF) for the synthetic aperture sequential beamforming (SASB) of VS imaging to improve image quality. The value of aGCF is adjusted by a sequence intensity factor (SIF) that is defined as the ratio between the effective low resolution scan lines (LRLs) intensity and total… More >

    Stephanie M. Ford1, Matthew T. McPheeters2, Yves T. Wang3, Pei Ma13, Shi Gu3, James Strainic4, Christopher Snyder4, Andrew M. Rollins3, Michiko Watanabe2, Michael W. Jenkins2

    Congenital Heart Disease, Vol.12, No.3, pp. 322-331, 2017, DOI:10.1111/chd.12443

    Abstract Background: The relationship between changes in endocardial cushion and resultant congenital heart diseases (CHD) has yet to be established. It has been shown that increased regurgitant flow early in embryonic heart development leads to endocardial cushion defects, but it remains unclear how abnormal endocardial cushions during the looping stages might affect the fully septated heart. The goal of this study was to reproducibly alter blood flow in vivo and then quantify the resultant effects on morphology of endocardial cushions in the looping heart and on CHDs in the septated heart.
    Methods: Optical pacing was applied to create regurgitant flow in… More >

    Abstract Optical coherence tomography (OCT) is a new intravascular imaging technique with high resolution and could provide accurate morphological infor￾mation for plaques in coronary arteries. However, its segmentation is still com￾monly performed manually by experts which is time-consuming. The aim of this study was to develop automatic techniques to characterize plaque components and quantify plaque cap thickness using 3 machine learning methods including convolutional neural network (CNN) with U-Net architecture, CNN with Fully convolutional DenseNet (FC-DenseNet) architecture and support vector machine (SVM). In vivo OCT and intravascular ultrasound (IVUS) images were acquired from two patients at Emory University with informed consent… More >

    In Vivo Biomechanical Measurements Using Vibrational Optical Coherence Tomography

    Frederick H. Silver1,*, Ruchit Shah2

    Molecular & Cellular Biomechanics, Vol.16, Suppl.2, pp. 71-71, 2019, DOI:10.32604/mcb.2019.08147

    Abstract Vibrational Optical Coherence Tomography (VOCT) is new technique capable of noninvasively and nondestructively measuring the biomechanical properties of tissues in vivo. The technology utilizes audible sound combined with infra-red light applied transversely to the tissue surface to obtain the resonant frequencies of both the cellular and extracellular components of tissue. The measured value of the resonant frequency is related to the elastic modulus and the sample dimensions. The technique is calibrated by making in vitro measurements of the Young’s modulus using uniaxial tensile experiments on the same samples used to make VOCT measurements. In this presentation we describe the details… More >
