Using Planetscope imagery, we trained a random forest model to detect Callery pear (Pyrus calleryana) throughout a diverse urban landscape in Columbia, Missouri. The random forest model had a classification accuracy of 89.78%, a recall score of 0.693, and an F1 score of 0.819. The key hyperparameters for model tuning were the cutoff and class-weight parameters. After the distribution of Callery pear was predicted throughout the landscape, we analyzed the distribution pattern of the predictions using Ripley's K and then associated the distribution patterns with various socio-economic indicators. The analysis identified significant relationships between the distribution of the predicted Callery pear and population density, median household income, median year the housing infrastructure was built, and median housing value at a variety of spatial scales. The findings from this study provide a much-needed method for detecting species of interest in a heterogenous landscape that is both low cost and does not require specialized hardware or software like some alternative deep learning methods.

remotesensing technology has become increasingly important in recent years due to its ability to collect high-resolution images of agricultural fields. One of the most popular methods for crop classification in agricultural fields is object-based image analysis (OBIA). At the same time, the convolutional long short-term memory (ConvLSTM) network has shown great potential in processing spatiotemporal *** this study, we proposed a new model called OB-ConvLSTM (Object-based ConvLSTM) that combines OBIA and ConvLSTM for spatiotemporal crop classification tasks. This model extracts crop spectral information from the spatial dimension of remotesensingimages, extracts crop growth information from multiple remotesensingimages in the temporal dimension, and synthesizes the spatial and temporal dimension information to improve crop classification accuracy. Compared with traditional crop classification models based on single temporal remotesensing, the model proposed in this study is superior to existing models in classification accuracy and model robustness. The proposed OB-ConvLSTM model has been applied to crop classification tasks in major crop-producing regions, achieving over 93% of the crop species recognition accuracy, with mIoU reaching 83%.The main contribution of this study is to design a temporal remotesensingimage semantic segmentation model structure suitable for field crop classification, combining the OBIA method with ConvLSTM and improving the model's performance by optimizing model components such as activation functions and optimizers. Specifically, there are several innovations in the following aspects: First, to facilitate model input, this study uses the SLIC algorithm to segment remotesensingimages into uniformly sized superpixel objects and aligns the superpixel objects in the temporal dimension;Subsequently, we used the ConvLSTM model totrain and classify superpixel objects with temporal information, and adopted the Mish activation functi

Over the years, many solutions have been suggested in order to improve object detection in maritime environments. However, none of these approaches uses flight information, such as altitude, camera angle, time of the day, and atmospheric conditions, to improve detection accuracy and network robustness, even though this information is often available and captured by the UAV. This work aims to develop a network unaffected by image-capturing conditions, such as altitude and angle. To achieve this, metadata was integrated into the neural network, and an adversarial learning training approach was employed. This was built on top of the YOLOv7, which is a state-of-the-art realtime object detector. To evaluate the effectiveness of this methodology, comprehensive experiments and analyses were conducted. Findings reveal that the improvements achieved by this approach are minimal when trying to create networks that generalize more across these specific domains. The YOLOv7 mosaic augmentation was identified as one potential responsible for this minimal impact because it also enhances the model's ability to become invariant to these image-capturing conditions. Another potential cause is the fact that the domains considered (altitude and angle) are not orthogonal with respect to their impact on captured images. Further experiments should be conducted using datasets that offer more diverse metadata, such as adverse weather and sea conditions, which may be more representative of real maritime surveillance conditions.

The purpose is to improve the design effect of high-level dance movements and help dancers to better master these movements. The body changes with advanced dance movements based on deep learning (DL) algorithm and Internet of Things (IoT) technology are analyzed to promote the practical application of biological image visualization technology. Firstly, DL is applied for imagerecognition, and secondly, the technical architecture of IoT technology is constructed. Finally, DL and IoT-edge computing (IoT-EC) are employed to establish the network structure of the dance generation model. The experimental results indicate that IoT-EC based on DL significantly enhances the efficiency of resource allocation and effectively reduces the server processing time. For 200 tasks in the workspace, deep reinforcement learning can be optimized in only 8 s. When there are 800 tasks in some workspaces, the edge server takes 21 s to optimize deep reinforcement learning (DRL). Besides, this scheme can control the energy consumption of the server in the calculation process while dramatically reducing the average waiting time. The application of these technologies in the dance movement has extensively promoted the progress and development of the dance industry. The present work provides references DL in imagerecognition and remotesensingimage classification.

Earth observations from remotesensingimagery play an important role in many environmental applications ranging from natural resource (e.g., crops, forests) monitoring to man-made object (e.g., builds, factories) recognition. Most widely used optical remotesensing data however is often contaminated by clouds making it hard to identify the objects underneath. Fortunately, with the recent advances and increased operational satellites, the spatial and temporal density of image collections have significantly increased. In this paper, we present a novel deep learning-based imputation technique for inferring spectral values under the clouds using nearby cloud-free satellite image observations. The proposed deep learning architecture, extended contextual attention (ECA), exploits similar properties from the cloud-free areas to tackle clouds of different sizes occurring at arbitrary locations in the image. A contextual attention mechanism is incorporated to utilize the useful cloud-free information from multiple images. To maximize the imputation performance of the model on the cloudy patches instead of the entire image, a two-phase custom loss function is deployed to guide the model. To study the performance of our model, we trained our model on a benchmark Sentinel-2 dataset by superimposing real-world cloud patterns. Extensive experiments and comparisons against the state-of-the-art methods using pixel-wise and structural metrics show the improved performance of our model. Our experiments demonstrated that the ECA method is consistently better than all other methods, it is 28.4% better on MSE and 31.7% better on cloudy MSE as compared to the state-of-the-art EDSR network.
