remotesensingimage scene classification plays an important role in remotesensingimage retrieval, land-use identification and urban planning. Deep learning brings great opportunity to the research in this field, but it transfers the difficulty of traditional characteristic engineering to the design of network structure. In this paper, we focus on the automatic design of the network model and propose a remotesensing scene classification method based on Neural Architecture Search Network (NASNet). We further use the transfer learning technology to make the designed network well migrated to the remotesensing scene classification data set. This method can automatically build the appropriate network structure according to the application. We compare the proposed method on a publicly large-scale dataset with several convolutional neural network (CNN) models. The experimental results demonstrate that the proposed method provides state-of-the-art performance compared with the traditional artificial neural network.

Unlike natural images, remotesensingimages are usually multispectral. And the lack of sufficient labeled data puts a limit on supervised learning for remotesensingimage retrieval. In this paper, we propose a novel method for unsupervised multispectral remotesensingimage retrieval. The proposed method makes use of the unsupervised representation learning ability of GAN. Meanwhile, a new reconstruction loss exploits the latent codes in GAN to make the final output informative and representative. Transfer learning and color histograms are used to generate an estimated similarity matrix to further guide the training. Hash constraints can make the output codes binary and compact. In the testing stage, the hash codes of multispectral images can be computed in an end-to-end manner. Experiments on a multispectral remotesensingimage dataset, EuroSAT [1], show the superiority of the proposed method over other state-of-the-art methods.

Jose Manuel Bioucas-Dias was an outstanding expert in many different IEEE-related areas, including inverse problems in imaging, signal and imageprocessing, pattern recognition, optimization, and remotesensing. He authored or co-authored more than 250 publications, including more than 100 journal papers (66 of which published in IEEE journals) and over 200 peer-reviewed international conference papers and book chapters. His contributions have been extremely influential in many different fields, namely phase estimation and unwrapping, convex optimization and Bayesian inference for imaging inverse problems, with a special emphasis on remotesensing, including synthetic aperture radar (SAR), hyperspectral unmixing, fusion, superresolution, classification, and segmentation. In this paper, we provide an overview of his outstanding contributions to remotesensingimageprocessing.

An image deformation algorithm is integrated with a Gaussian process classifier for application to remote-sensing tasks in which data is in the form of imagery. To combine these disparate techniques, we introduce a novel kernel covariance function for the Gaussian process that allows us to incorporate the result of the image deformation algorithm into a rigorous Bayesian classification framework. The resulting classifier is completely non-parametric in the sense that no parameters or hyperparameters must be learned. The promise of the proposed algorithm is demonstrated on a data set of real, measured land mine data.

remotesensing has a growing relevance in the modern society with the development of imageprocessing of satellite imagery. However, due to the limitations of the current imaging sensors and the complex atmospheric conditions, we are facing great challenges in the remotesensing applications due to the limited spatial, spectral, radiometric and temporal resolutions. Therefore, super-resolution techniques have attracted much attention by which the low quality low resolution remotesensingimages are enhanced. In this paper, we discuss the challenges in remotesensingimage super-resolution and thereafter review the relevant approaches. More specifically, the different categories of remotesensing techniques, i.e., the learning-based, interpolation based, frequency domain based, and probability based methods, are reviewed and discussed. Furthermore, the super-resolution applications are discussed and insightful comments on future research directions are provided.

image smoothing and edge detection by use of Gaussian filters are much used in remotesensingimageprocessing. In the present paper, we propose Hermite integration method to realize Gaussian filters and their derivatives by use of orthogonal polynomial theory and interpolation. We analyze at first 1-D cases and show that the output of a Gaussian filter can be calculated by the weighted sum of the input signal sampled at the positions corresponding to the Hermite polynomial roots, which gives a much better algebraic precision and a less important complexity than the classical mask convolution method. The digital implementation is then presented. The Hermite integration method is then generalized to the calculation of Gaussian-filtered derivatives and to multidimensional cases, such as 2-D imageprocessing in remotesensing. Our method shows the following advantages: (1) Better algebraic precision. (2) Constant and reduced computational complexity independent of the filter window size. (3) processing completely in parallel. (4) The possibility to detect edges with subpixel precision. The method is implemented and tested for artificial data and real remotesensingimages and is compared with the classical mask convolution method, the experimental results are reported as well.

This paper presents the image information mining based on a communication channel concept. The feature extraction algorithms encode the image, while an analysis of topic discovery will decode and send its content to the user in the shape of a semantic map. We consider this approach for a real meaning based semantic annotation of very high resolution remotesensingimages. The scene content is described using a multi-level hierarchical information representation. Feature hierarchies are discovered considering that higher levels are formed by combining features from lower level. Such a level to level mapping defines our methodology as a deep learning process. The whole analysis can be divided in two major learning steps. The first one regards the Bayesian inference to extract objects and assign basic semantic to the image. The second step models the spatial interactions between the scene objects based on Latent Dirichlet Allocation, performing a high level semantic annotation. We used a WorldView2 image to exemplify the processing results.

High resolution image provides an important new data source for object recognition. A method based on pyramid-structured wavelet transform (PSWT) for object recognition on high-resolution remotesensingimage is put forward. First, the model image and the search image are decomposed to pyramid-structure by wavelet transform. A novel match metric is computed using direction vectors constructed by the high-frequency information of wavelet coefficients. This metric is robust to occlusion, clutter, illumination changes. And the matching can be implemented until the highest level of decomposing to track said instances of the model in the lowest one. The tests confirm that the proposed algorithm is efficient and reliable.

remotesensing is basically the method of detection of the physical parameters of a specific area along with that it also monitors the area by measuring the radiation parameters from satellite. The cameras are designed to gather remotely sensed images, which are used to sense things of the earth's surface. Like the cameras on the satellites and the airplanes takes pictures of the different area, allowing us to get every minute detail about it. Now, change detection is the process to identify the changes or differences in various parts of land characteristics at different intervals. This process can be carried by manual observation or by the use of remotesensing software. Because of the rapid urbanization there has been a significant impact on resources and urban environment. But with the use of high quality multi-spatial and multi-temporal remotesensing data, it is quite easy to possibly observe the changes in the urban environment. Therefore, the given study aims to quantify changes in the urban area of Symbiosis University Nagpur, Maharashtra India using Land satellite image. These changes of urbanization are detected by satellite images of Land-Sat MSS in march-2016, march-2018 and may-2020 using a geographic information system (GIS). The change of urbanization in Symbiosis University is for building, road, garden and ground are 17.35%, 20.71%, 1.65% and 0.89% respectively and the total change is 43.51%. From this change we will receive the taxes as per its ongoing construction and it will be easy for government.
