چکیده
Deep learning-based super-resolution (SR) methods have been widely used in natural images; however, their applications satellite-derived sea surface temperature (SST) not yet fully discussed. Hence, it is necessary to analyze the validity of deep SR SST reconstruction. In this study, an model, including multiscale feature extraction and multireceptive field mapping, was first proposed. Then, proposed model four other existing models were applied reconstruction analyzed. First, compared with bicubic interpolation method, can improve accuracy. Compared models, achieve lowest mean squared error (MAE) East China Sea (ECS), northwest Pacific (NWP) west Atlantic (WA), second-lowest MAE southeast (SEP); root (RMSE) ECS WA, RMSE NWP SEP. Additionally, ODRE acquire highest or second-highest peak single-to-noise ratio structural similarity index ECS, NWP, Moreover, number missing pixels variety are two essential factors performance. The process enhance performance, especially for small regions stable regions. Finally, while a deeper network be helpful achieving approach simply adding more dilation convolutions may

متن کاملSuper-Resolution via Deep Learning
The recent phenomenal interest in convolutional neural networks (CNNs) must have made it inevitable for the super-resolution (SR) community to explore its potential. The response has been immense and in the last three years, since the advent of the pioneering work, there appeared too many works not to warrant a comprehensive survey. This paper surveys the SR literature in the context of deep le...
متن کاملEffective deep learning training for single-image super-resolution in endomicroscopy exploiting video-registration-based reconstruction
Purpose: Probe-based Confocal Laser Endomicroscopy (pCLE) is a recent imaging modality that allows performing in vivo optical biopsies. The design of pCLE hardware, and its reliance on an optical fibre bundle, fundamentally limits the image quality with a few tens of thousands fibres, each acting as the equivalent of a single-pixel detector, assembled into a single fibre bundle. Video-registrat...
متن کاملImage Super-Resolution Reconstruction Based On Multi-Dictionary Learning
In order to overcome the problems that the single dictionary cannot be adapted to variety types of images and the reconstruction quality couldn’t meet the application, we propose a novel Multi-Dictionary Learning algorithm for feature classification. The algorithm uses the orientation information of the low resolution image to guide the image patches in the database to classify, and designs the...
متن کاملDeep Depth Super-Resolution: Learning Depth Super-Resolution Using Deep Convolutional Neural Network
Depth image super-resolution is an extremely challenging task due to the information loss in sub-sampling. Deep convolutional neural network have been widely applied to color image super-resolution. Quite surprisingly, this success has not been matched to depth super-resolution. This is mainly due to the inherent difference between color and depth images. In this paper, we bridge up the gap and...
