Gesture recognition is an open phenomenon in computer vision, and one of the topics of current interest. Gesture recognition has many applications in the interpretation of sign language in deaf-mutes, one is in human-computer interaction, and the other is in immersive game technology. For this purpose, we have developed a model of image processing recognition of gestures, based on artificial neural networks, starting from data collection, identification, tracking and classification of gestures, to the display of the obtained results. We propose an approach to contribute to the translation of sign language into voice/text format. In this paper, we present a Moroccan sign language recognition system using a Convolutional neural Network (CNN). This system includes an important data set of more than 20 files. Each file contains 1,000 static images of each signal from several different angles that we collected with the camera. Different Sign Language models were evaluated and compared with the proposed CNN model. The proposed system achieved 99.33% and achieved the best performance with an accuracy rate of 98.7%. © 2022 River Publishers.

Flower classification is vital in many disciplines, including botany, agriculture, environmental studies, and industry. Dependent traditionally on professional knowledge, improvements in digital image processing and machine learning techniques have changed this activity. This paper investigates the use of Convolutional neural networks (CNNs) for four classifications bellflower, common daisy, rose, and sunflower - of flower images. Based on a Kaggle dataset, the work employs a CNN model with an astonishing 92% general accuracy. Stressing amazing accuracy and recall for roses and sunflowers, precision, recall, F1-score, and confusion matrix analysis serves to assess the performance of the model. Although the model excels in many aspects, it might need additional improvement to differentiate common daisies. The results show how successfully CNNs automate floral classification, therefore helping botanical study, commercial floriculture, agricultural management, and floral design. This work provides a good foundation for the next research aiming to increase model accuracy for less represented classes and investigate new techniques to address difficult classification challenges. © 2024 IEEE.

Considering the learning advantage of reservoir computing, the echo state network is introduced to replace the full connection layer of the traditional convolutional neural network, and thus, an improved convolutional neural network is proposed for failure detection classification of boiler four tube in this paper. For the failure detection of boiler four tube, due to the difficulty of manual classification, it is necessary to classify the collected pictures by using an improved intelligent classification method. According to the image information processing ability of the convolutional neural network, the image feature information of boiler four tube can be extracted. Because the extracted image feature information is introduced into the reservoir, the failure detection type of boiler four tube can be classified more accurately by using the learning ability of echo state network. In order to reduce the influence of the reservoir parameters on the classification accuracy of the proposed method, a parameter optimization method is given for optimizing the image classification model. Through using the collected images, the simulation results show that the classification accuracy of the proposed classification method reaches 90.1%. © 2022 IEEE.

Synthetic aperture radar (SAR) image change detection has a very important and wide applications, and the complexity of SAR image data makes the accurate identification of change regions a challenging task. Many Convolutional neural networks (CNN) have been successfully applied to change detection tasks, but most of them have complex structures and heavy computation, so this paper proposes an unsupervised lightweight Convolutional neural Network for change detection. We introduce conditionalized convolution (CondConv) and ConvNeXt block into the change detection task to improve the performance of the network in recognizing complex objects, and we can refer to this method as DNNet for short. In this paper, the bi-temporal images are first subjected to differential analysis, and then the convolutional neural network is trained with pseudo-labels generated by clustering. The effectiveness of DNNet is verified on three real SAR datasets and compared with several state-of-the-art methods. Experiments results show that the proposed method has better effectiveness.

The rise of cultural tourism in India and massive digitization over the last decade has necessitated preserving Indian art forms. Recent advances in artificial intelligence (AI) have provided the tools and techniques to make these efforts more efficient. The potential research areas involved are digital image processing, computer vision, and machine intelligence. Since researchers have not much explored the scope of the digital preservation of Indian classical dance, this paper contributes a method to classify different Indian classical dance forms. Computerized dance modeling offers a wide range of uses, including cultural conservation, online learning, entertainment, and even remedial treatment. Because the dataset is small, the paper uses transfer learning models for feature extraction and deep neural networks for classification. The proposed method showed a remarkable accuracy of 97.05 percent. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

Numerous medical studies have shown that Alzheimer's disease (AD) was present decades before the clinical diagnosis of dementia. As a result of the development of these studies with the discovery of many ideal biomarkers of symptoms of Alzheimer's disease, it became clear that early diagnosis requires a high-performance computational tool to handle such large amounts of data, as early diagnosis of Alzheimer's disease provides us with a healthy opportunity to benefit from treatment. The main objective of this paper is to establish a complete framework that is based on deep learning approaches and convolutional neural networks (CNN). Four stages of AD, such as (I) preprocessing and data preparation, (ii) data augmentation, (iiI) cross-validation, and (IV) classification and feature extraction based on deep learning for medical image classification, are implemented. In these stages, two methods are implemented. The first method uses a simple CNN architecture. In the second method, the VGG16 model is the pre-trained model that is trained on the imageNet dataset but applies the same model to the different datasets. We apply transfer learning, meaning, and fine-tuning to take advantage of the pre-trained models. Seven performance metrics are used to evaluate and compare the two methods. Compared to the most recent effort, the proposed method is proficient of analyzing AD, moreover, entails less labeled training samples and minimal domain prior knowledge. A significant performance gain on classification of all diagnosis groups was achieved in our experiments. The experimental findings demonstrate that the suggested designs are appropriate for basic structures with minimal computational complexity, overfitting, memory consumption, and temporal regulation. Besides, they achieve a promising accuracy, 99.95% and 99.99% for the proposed CNN model in the classification of the AD stage. The VGG16 pre-trained model is fine-tuned and achieved an accuracy of 97.44% for AD stage clas

Attention-only Transformers [34] have been applied to solve Natural Language processing (NLP) tasks and Computer Vision (CV) tasks. One particular Transformer architecture developed for CV is the Vision Transformer (ViT) [15]. ViT models have been used to solve numerous tasks in the CV area. One interesting task is the pose estimation of a human subject. We present our modified ViT model, Un-TraPEs (UNsupervised TRAnsformer for Pose Estimation), that can reconstruct a subject's pose from its monocular image and estimated depth. We compare the results obtained with such a model against a ResNet [17] trained from scratch and a ViT finetuned to the task and show promising results.

Optimal transport (OT) barycenters are a mathematically grounded way of averaging probability distributions while capturing their geometric properties. In short, the barycenter task is to take the average of a collection of probability distributions w.r.t. given OT discrepancies. We propose a novel algorithm for approximating the continuous Entropic OT (EOT) barycenter for arbitrary OT cost functions. Our approach is built upon the dual reformulation of the EOT problem based on weak OT, which has recently gained the attention of the ML community. Beyond its novelty, our method enjoys several advantageous properties: (i) we establish quality bounds for the recovered solution;(ii) this approach seamlessly interconnects with the Energy-Based Models (EBMs) learning procedure enabling the use of well-tuned algorithms for the problem of interest;(iii) it provides an intuitive optimization scheme avoiding min-max, reinforce and other intricate technical tricks. For validation, we consider several low-dimensional scenarios and image-space setups, including non-Euclidean cost functions. Furthermore, we investigate the practical task of learning the barycenter on an image manifold generated by a pretrained generative model, opening up new directions for real-world applications.

Agricultural industry has grown significantly bring sustainable farming practices in improving the food quality, enhancing agricultural productivity and global food security. However, the crop yield and its quality are impacted when the timely identification and management of the crop diseases are not promptly solved. Thus, the crop disease detection becomes the critical aspect in the smart agriculture. Several researchers addressed this crop disease detection by developing optimized solutions through machine learning, deep learning and image processing techniques. However, these techniques face serious challenges when deployed in real-time crop disease identification problems like annotated training images, capturing long-range dependencies, adaption to real-time changes evolving over time and so on. This leads to performance degradation seeking for more powerful applications like some advanced deep learning techniques, in particular, the transformer models. In this paper, a novel crop disease detection model known as CropViT was proposed based on Vision Transformer. This CropViT was developed by fine-tuning the architecture of existing Vision Transformer and PlantVillage dataset was used in the experimental study. Nine crop species were selected and trained using CropViT whose performance was then compared with traditional Convolutional neural Network model. The experimental study clearly showed the highest mean accuracy of 98.64% for CropViT when compared to 95.52% mean accuracy for traditional CNN. The experimental results also outperformed other existing state-of-the-art models. Finally, the work was concluded with the discussion of experimental results and its future scope of work. © 2024 IEEE.
