AIM To treated with electrochemotherapy (ECT) a prospective case series of patients with liver cirrhosis and Vp3-Vp4- portal vein tumor thrombus (PVTT) from hepatocellular carcinoma (HCC), in order to evaluate the feasibility, safety and efficacy of this new non thermal ablative technique in those patients. METHODS Six patients (5 males and 1 female), aged 61-85 years (mean age, 70 years), fo...
iran has not yet gained the desired place in world date market, due to not considering the world standards in the processes of grading and packaging. machine vision and image processing are two of the new techniques that have found their places of application in agricultural industry. in this research, a solution has been introduced for classification of mozafati date introducing 5 different gr...
1-Introduction The location of shorelines and the state of their changes in the past, present and over time are important for scientists, engineers and managers. For example, analyzing shoreline information for coastal protection design, policy development, updating and reviewing numerical models, assessing sea level rise, developing risk areas for coastal development, achieving the definition...
视频超分辨率技术在卫星遥感侦测、视频监控和医疗影像等方面发挥着关键作用，在各领域具有广阔的应用前景，受到广泛关注，但传统的视频超分辨率算法具有一定局限性。随着深度学习技术的愈发成熟，基于深度神经网络的超分辨率算法在性能上取得了长足进步。充分融合视频时空信息可以快速高效地恢复真实且自然的纹理，视频超分辨率算法因其独特的优势成为一个研究热点。本文系统地对基于深度学习的视频超分辨率的研究进展进行详细综述，对基于深度学习的视频超分辨率技术的数据集和评价指标进行全面归纳，将现有视频超分辨率方法按研究思路分成两大类，即基于图像配准的视频超分辨率方法和非图像配准的视频超分辨率方法，并进一步立足于深度卷积神经网络的模型结构、模型优化历程和运动估计补偿的方法将视频超分辨率网络细分为10个子类，同时利用充足的实验数据对每种方法的核心思想以及网络结构的优缺点进行了对比分析。尽管视频超分辨率网络的重建效果在...
