چکیده

Image super-resolution (SR) techniques can benefit a wide range of applications in the remote sensing (RS) community, including image classification. This issue is particularly relevant for classification on time series data, considering RS datasets that feature long temporal coverage generally have limited spatial resolution. Recent advances deep learning brought new opportunities enhancing resolution historic data. Numerous convolutional neural network (CNN)-based methods showed superior performance terms developing efficient end-to-end SR models natural images. However, such were rarely exploited promoting based multispectral paper proposes novel CNN-based framework to enhance Thereby, proposed model employs Residual Channel Attention Networks (RCAN) as backbone structure, whereas this structure uniquely integrate tailored channel-spatial attention and dense-sampling mechanisms improvement. Subsequently, state-of-the-art classifiers are incorporated produce maps enhanced The experiments proved enable unambiguously better compared RCAN other (deep learning-based) techniques, especially domain adaptation context, i.e., leveraging Sentinel-2 images generating Landsat Furthermore, experimental results confirmed multi-temporal bring substantial improvement fine-grained land use

Residual Dense Network for Image Super-Resolution

A very deep convolutional neural network (CNN) has recently achieved great success for image super-resolution (SR) and offered hierarchical features as well. However, most deep CNN based SR models do not make full use of the hierarchical features from the original low-resolution (LR) images, thereby achieving relatively-low performance. In this paper, we propose a novel residual dense network (...

Multi-temporal remote sensing image classification - A multi-view approach

Multispectral remote sensing images have been widely used for automated land use and land cover classification tasks. Often thematic classification is done using single date image, however in many instances a single date image is not informative enough to distinguish between different land cover types. In this paper we show how one can use multiple images, collected at different times of year (...

A Method of Spatial Mapping and Reclassification for High-Spatial-Resolution Remote Sensing Image Classification

This paper presents a new classification method for high-spatial-resolution remote sensing images based on a strategic mechanism of spatial mapping and reclassification. The proposed method includes four steps. First, the multispectral image is classified by a traditional pixel-based classification method (support vector machine). Second, the panchromatic image is subdivided by watershed segmen...

Single-image Super Resolution for Multispectral Remote Sensing Data Using Convolutional Neural Networks

In optical remote sensing, spatial resolution of images is crucial for numerous applications. Space-borne systems are most likely to be affected by a lack of spatial resolution, due to their natural disadvantage of a large distance between the sensor and the sensed object. Thus, methods for single-image super resolution are desirable to exceed the limits of the sensor. Apart from assisting visu...
