Special Issue Information

Dear Colleagues,

In the last decade, urban growth has increased exponentially, but urban planning and management have not undergone the necessary changes to generate and transform urban spaces into safer, more efficient, transformable, inclusive, and sustainable spaces. Smart cities represent an evolution towards the inclusion of digitalization within cities, enabling the application of improvement development techniques that increase the possibility of solving environmental problems. Furthermore, humanity is facing a global pandemic, COVID-19, which makes it even more difficult to develop improvements given this health crisis and its relationship with all aspects of city life. 

Therefore, given the opportunity for data management, processing, and interpretation that machine learning-based technologies possess, we are committed to their inclusion in the smart city in a global manner, allowing us to address sustainability from the conception of digital solutions that pave the way for efficient and transformable spaces in accordance with the Sustainable Development Goals (SGDs) and the guidelines set forth by the European Union's Agenda 2030. 

This Special Issue will include studies investigating the reliable implementation of machine learning technologies in smart cities to improve sustainability. The topics of interest include but are not limited to the following:

  • machine learning technologies·      
  • data and information processing·      
  • smart city-oriented data management systems·      
  • prediction and simulation of city areas to improve sustainability (transport, parking, public systems, etc.)

This study proposed an AlexNet-based crowd anomaly detection model in the video (image frames). The proposed model was comprised of four convolution layers (CLs) and three Fully Connected layers (FC). The Rectified Linear Unit (ReLU) was used as an activation function, and weights were adjusted through the backpropagation process. The first two CLs are followed by max-pool layer and batch normalization. The CLs produced features that are utilized to detect the anomaly in the image frame. The proposed model was evaluated using two parameters—Area Under the Curve (AUC) using Receiver Operator Characteristic (ROC) curve and overall accuracy. Three benchmark datasets comprised of numerous video frames with various abnormal and normal actions were used to evaluate the performance. Experimental results revealed that the proposed model outperformed other baseline studies on all three datasets and achieved 98% AUC using the ROC curve. Moreover, the proposed model achieved 95.6%, 98%, and 97% AUC on the CUHK Avenue, UCSD Ped-1, and UCSD Ped-2 datasets, respectively. Full article

Recently, remote sensing satellite image analysis has received significant attention from geo-information scientists. However, the current geo-information systems lack automatic detection of several building characteristics inside the high-resolution satellite images. The accurate extraction of buildings characteristics helps the decision-makers to optimize urban planning and achieve better decisions. Furthermore, Building orientation angle is a very critical parameter in the accuracy of automated building detection algorithms. However, the traditional computer vision techniques lack accuracy, scalability, and robustness for building orientation angle detection. This paper proposes two different approaches to deep building orientation angle estimation in the high-resolution satellite image. Firstly, we propose a transfer deep learning approach for our estimation task. Secondly, we propose a novel optimized DCRN network consisting of pre-processing, scaled gradient layer, deep convolutional units, dropout layers, and regression end layer. The early proposed gradient layer helps the DCRN network to extract more helpful information and increase its performance. We have collected a building benchmark dataset that consists of building images in Riyadh city. The images used in the experiments are 15,190 buildings images. In our experiments, we have compared our proposed approaches and the other approaches in the literature. The proposed system has achieved the lowest root mean square error (RMSE) value of 1.24, the lowest mean absolute error (MAE) of 0.16, and the highest adjusted R-squared value of 0.99 using the RMS optimizer. The cost of processing time of our proposed DCRN architecture is 0.0113 ± 0.0141 s. Our proposed approach has proven its stability with the input building image contrast variation for all orientation angles. Our experimental results are promising, and it is suggested to be utilized in other building characteristics estimation tasks in high-resolution satellite images. Full article
