With the continuous increase in the number of internet users, the explosion of multimodal data on the web has led to a growing demand for image retrieval. Current text-to-image retrieval systems often rely on keyword matching, which frequently fails to accurately capture users' retrieval needs. This work proposes a text-to-image retrieval method based on zero-shot transfer learning with the CLIP model and vector database, designed to be applied in text-to-image retrieval systems. By leveraging the semantic alignment capability of the CLIP model for text and images, this study effectively addresses the semantic gap problem in text-to-image retrieval. Additionally, the method utilizes the Milvus database for efficient storage and retrieval of image feature vectors, thereby enhancing system stability. Experimental results on the Flickr30k dataset demonstrate that this method improves the accuracy of text-to-image retrieval, verifying its effectiveness. Furthermore, this work extends the proposed method by incorporating the iFLYTEK Spark Cognitive Model to support image retrieval using Chinese text descriptions, further broadening the system's applicability and reliability. © 2024 IEEE.

In order to solve the problem of low precision and low stability of deep learning network for industrial equipment fault recognition under strong background noise, a method of equipment fault image recognition based on deep integrated learning with hyperparameter optimization was proposed. Firstly, the time-frequency image data set is constructed by using two-dimensional wavelet transform of the original vibration signal. Secondly, the noise resistance of each CNN network architecture is tested, and the change of network performance is studied by embedding different noise intensities into the data. Then, group optimization algorithm is used to optimize the learning rate and batch sampling parameters of the optimal architecture model. Finally, decision fusion is used to integrate the trained model, so as to improve the stability and image recognition accuracy of the integrated network. Verified by the bearing data of Western Reserve University, the proposed algorithm has good diagnostic accuracy and stability. © 2024 IEEE.

The development of semantic communication has promoted the research on image transmission. Content and style are two crucial characteristics of image information. Existing studies have explored image information transmission and recovery methods in semantic communication systems, but do not consider both image style information and content information simultaneously. To address this issue, based on deep joint source-channel coding (JSCC) structure, a novel system named semantic communication based on content style adaption (CSASC) for image transmission is proposed in this paper. Specifically, a novel semantic information extraction method are designed to extract the semantic content information and semantic style information of images, meanwhile an image content-style adaptive reconstruction method is proposed by fusing semantic content and semantic style features to improve the image reconstruction accuracy. In addition, the impact of the weighting of semantic style and content information on image reconstruction quality is analyzed. Results demonstrate that the proposed method has better recovery results compared with existing image semantic communication methods. © 2024 IEEE.

With the continuous development of radar jamming methods and styles, radar systems are facing more and more complex electromagnetic environment, resulting in limited suppression performance through spatial anti-jamming measures solely. In order to solve the problem, this paper proposes an anti-jamming method based on joint spatial-polarimetric processing for Frequency Diverse Array Multiple-Input Multiple-Output (FDA-MIMO) system. Firstly, the signal model of Polarimetric FDA-MIMO (PFDA-MIMO) is established. based on this model, a joint spatial-polarimetric adaptive filtering method is proposed and experiments are carried out to demonstrate the advantages of joint spatial-polarimetric processing in anti-jamming. Compared to the filtering method that only utilizing the spatial information, this method has a better performance dealing with multidimensional jamming and improves the ability of FDA-MIMO in resisting main lobe jamming. © 2024 SPIE.

Human-hand gesture recognition using millimetre wave radar is attractive in human-computer interfaces, industrial internet of Things, and smart home. However, the existing CNN or RNN model is so complex and large that it is hard to apply to mobile vision tasks and embedded devices. This paper proposes dual lightweight convolutional neural networks, MobileViT and knowledge distillation, to solve this problem. Firstly, we acquire the original radar echoes of frequency-modulated continuous wave (FWCW) signal and reshape the three-dimensional matrix by Chirps * Samples * Frames. Then, we perform the signal processing method to eliminate the noise and static background. Secondly, we employ the Fast Fourier Transform to extract the hand gestures feature map of distance and Doppler information. Finally, the feature map is input into the modified MobileViT to recognize dynamic hand gestures, and knowledge distillation models is used to simplify the model structure. The experimental results show that the parameter space complexity of the constructed model is reduced to 0.018 M, and the computational complexity is 0.082 GFLOPs after knowledge distillation *** method is verified in 12 complex gesture. It has the potential to be applied in mobile tasks and embedded devices. © 2025 SPIE.

The early recognition of retinal disorders such as cataracts, glaucoma, and retinal problems is highly dependent on high-resolution retinal imaging, which is a complex issue because of poor image quality and the lack of important features. The proposed Enhanced Edge Attention Super Resolution Convolutional Neural Network (EEASRCNN) is designed to improve the quality of retinal images high precisely. The model preserves important details like blood vessels and the optic disc by using a custom edge loss function, sharpening filters, and combined attention mechanisms. With a high structural similarity index (SSIM) and peak signal-to-noise ratio (PSNR) score and an accuracy of 97.16% in preserving structural details, EEASRCNN outperforms traditional super-resolution methods after being trained on a dataset of diverse retinal images. EEASRCNN offers effective image super resolution in real-time medical image diagnosis. © 2025 IEEE.

Multiple aspects of our life could benefit from the IoT. A component of the 'connected house' is the internet of Things (IoT). All the programs below are the ones that need to be localized in some form. When applied to the first, IoT allows for the accurate localization of anything, even living creatures and humans. The second component tracks mobile targets such as toddlers and the elderly. When it comes to home safety and surveillance, smart homes offer features like geolocation and monitoring. A localization system is able to track almost anywhere or anything by combining information from multiple sources, such as wired and wireless networks. As time goes on, the internet of Things (IoT) becomes increasingly important and influences our daily lives in tangible ways. There is growing interest in the field of navigation IoT-based systems due to their widespread use in context-aware and localizationaware applications such as tracking, healthcare, and security. This subject has received a lot of attention as sensor technology and computational capacities improve. This study presents a brief overview of the localization techniques used by internet of Things-based indoor navigation systems at present. © 2023 IEEE.

Corn leaf diseases, consisting Common Rust, Gray Leaf Spot, and Blight, pose significant threats to worldwide farming by affecting crop harvest and standards. Blight causes rapid defoliation of plants;Common Rust brought on by Puccinia sorghi and Grey Leaf Spot reduces photosynthesis and yields losses. Early and accurate detection is crucial for timely intervention, reducing chemical dependency, and ensuring food security. This study leverages Residual Networks (ResNet) to advance disease detection. ResNet's deep residual learning architecture efficiently handles complex image classification tasks. Trained on maize leaf images, the ResNet model achieved 96% accuracy in classifying leaves into common rust, gray leaf spot, blight, and healthy categories. A model's high precision and recall significantly enhance detection accuracy. This work supports sustainable agriculture, promotes resilient agricultural practices, and contributes to food security by improving disease control and crop management through advanced technology.

We propose a multimodal medical image fusion method based on edge enhancement and detail preservation to address the issue of lost image details in current medical image fusion approaches. Firstly, we decompose the images from different modalities using the non-subsampled shearlet transform (NSST) to obtain their respective high-frequency and low-frequency subbands. Next, we employ a novel detail-preserving parameter adaptive pulse coupled neural network to fuse the high-frequency subbands, and an edge-enhanced weighted local energy method to fuse the low-frequency subbands. Finally, the fused image is reconstructed by performing inverse NSST on the fused high-frequency and low-frequency subbands. Experimental results demonstrate that our proposed method effectively preserves more detailed information from the source images and exhibits excellent performance in both subjective and objective evaluations when compared to seven commonly used multimodal medical image fusion methods. © 2024 SPIE.
