It is shown that any digital signal and image processing algorithms can be reduced to multivalued logic operations. The basis for this is signal models, in which each discrete level is associated with an element of the Galois field. Therefore, the development of algorithms and computing systems operating directly in Galois fields is topical. To simplify the calculation of products in Galois fields, in turn, it is convenient to pass from an element of the Galois field to the degree of a primitive element that defines this element. This allows the multiplication operation to be reduced to the addition operation. A specific example of an algorithm and a block diagram of a device that implements it, which allows such a reduction, are presented. This example demonstrates that for solving problems of digital signal and image processing, it is very important to take into account the specifics of specific Galois fields. © 2022 IEEE.

nowadays the need for a safe and at ease device is favored using every character in society. A fee-effective system is needed for Aerial surveillance systems capable of enhancing situational focus in the course of a couple of scales of place and time. With the assistance of an machine, we are capable of accumulating a device that could report unmanned vehicles and humans. With improvements in technology, Unmanned motors and optical sensors are being fast produced with powerful usage of resources, therefore, it has ended up being less complicated to get images from the UAV at a low price. But the selection of those pixy received is reduced because of climatic conditions like fog, rain, harsh sunlight, etc. So, we advocate a photograph processing technique as a manner to use algorithms that include single-scale retinex, Multiscale retinex, histogram equalization, and colour recuperation to grow the fine of photographs. These select images have a higher evaluation, and subsequently can be used for better item detection. 1. The program can determine the objects without getting observed.2. The program can find multiple items. Three. MSRP for similar processing like histogram equalization and item detection to get the exceptional possible output © 2023 IEEE.

Optical Character Recognition (OCR) is commonly referred as text recognition which poses a substantial issue in the computer vision tasks. Conventional optical character recognition systems frequently suffer in handwritten document recognition. To solve this, Deep Learning (DL) models have emerged as a powerful and advanced solution for character recognition. The present research offers a unique CNN-RNN model with an Attention Mechanism (CNN-RNN-AM) for English image character recognition. The process comprised many important phases, beginning with image collection from a user-defined dataset, then image pre-processesing includes grayscale conversion and noise reduction. For effective character recognition, the proposed approach integrates the segmentation process at multiple levels, including line segmentation, word segmentation, and character segmentation. Finally, the CNN-RNN with an attention mechanism is deployed for character recognition. The experimental findings demonstrated the remarkable efficacy of the suggested CNN-RNN-AM model. It outperformed other compared models by attaining an excellent character recognition accuracy of 99.89%. © 2023 IEEE.

Lane detection is an essential function for autonomous driving systems since it provides information about the vehicle's position and the road's geometry. However, there are problems with existing lane detection algorithms, such as shadows, uneven lighting, and traffic signs. In this work, a conventional image processing-based lane detection method based on the Canny edge detector and Hough transform is implemented. The algorithm is implemented and tested on two different platforms, the Raspberry Pi 4 B+ and the Nvidia Jetson Nano boards, utilizing both recorded and live-streaming videos. Our evaluation shows that the technique works effectively for lane detection, with Nvidia Jetson Nano outperforming Raspberry Pi 4 B+. The proposed system can be used for many autonomous driving tasks, such as lane changing, lane keeping, and collision avoidance. © 2023 IEEE.

One of the most difficult challenges in image processing is restoring a defocused image by reducing blur and noise. Blurring characterizes image deterioration, and recovery is accomplished by point spread function estimation and ideal image estimation processing was repeated. Ringing, or wavelike artifacts that arise along strong edges, is a difficult challenge in latent image restoration. Therefore, this paper will introduce an improved blind deconvolution for restoring blurry images using ringing removal process. This paper provides an improved deconvolution technique that uses blur kernel prediction based on dark channels before achieving clear image recovery. To hold picture information and beautify the rims of the ringing impact created at some point of the authentic clean picture recuperation process, an easy bilateral clear out is used. The ringing removal method L0 regularization is used with the restoration process, which can estimate a sharper image. By removing the difference map from the final deconvolution result, it is possible to get a clearer picture without ringing. Finally, the results are presented in terms of performance parameters such as signal-to-noise ratio (SNR), mean squared error (MSE), and peak signal-to-noise ratio (PSNR).The results show that the performance parameters of the improved blind deconvolution model are superior compared to existing image blur removal algorithms. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

This study investigates the efficiency of 2D thumbnail-based algorithms, complemented by non-visual information, in enhancing quality control for manufacturing processes characterized by high error rates like rimming. Amidst the challenges faced by traditional 3D technology-based quality control methods, such as extended computing times and the necessity for advanced hardware, this research proposes a different approach leveraging high-resolution 2D images and part metadata to identify defects. By employing Machine Learning techniques, specifically Mask R-CNN models enhanced with Squeeze-and-Excitation Blocks (SEBlocks) for detailed feature detection, and Random Forest classifiers for scale classification and tolerance validation, the study presents a cost-effective yet efficient alternative. The methodology encompasses four primary steps: image acquisition, enhanced hole detection, scale classification, and prediction optimization, concluding with diameter tolerance classification and validation. Employing a dataset of synthetic images annotated for hole locations, the system's performance is evaluated using metrics such as Intersection over Union (IoU), Dice score, and Mean Squared Error (MSE), demonstrating its efficacy in near-real-time defect detection. This research contributes to the field by offering an adaptable, scalable solution for quality control in manufacturing, significantly reducing dependency on costly hardware and paving the way for future innovations in process monitoring and defect detection after laser and machining processing. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2024.

Aliasing's Study on Bandpass Sampling

Aliasing's Study on Bandpass Sampling

The increase in the complexity of algorithms for digital processing of RF signals is limited by the need to increase the sampling rate. Sub-Nyquist sampling, in particular bandpass sampling, allows us to reduce the sampling rate, determined by the Nyquist-Shannon sampling theorem, and turn to baseband digital processing. In a large number of publications, the issues of choosing the sampling frequency, which makes it possible to eliminate aliasing, are considered. At the same time, there are works devoted to the restoration of signals distorted by aliasing. Therefore, digital signal processing algorithms are of interest, in which the presence of aliasing is allowed. These algorithms make it possible to further reduce the sampling rate and thus make it easier to process wideband signals or narrowband signals over a wider bandwidth. This paper shows that with a fixed sampling rate and a tunable bandwidth of the processed signals, various configurations of the relative position of the alias of the bandpass signal transferred to the first Nyquist zone and its mirror image are possible. The features of aliasing are considered for various configurations of the down-transferred spectrum and for various orders of aliasing. © 2022 IEEE.

The paper proposes the parameter optimization of image processing for contamination inspection of nonwoven fabrics. Currently, the automation of contamination inspection using image processing systems is being considered. In image processing, it is important to set the optimal parameters for the processing. However, it is necessary to search it from many combinations because there are some parameters. The proposed method searches for the optimal parameters based on a genetic algorithm. It reduces the search time in comparison with the conventional method. The paper indicates the effectiveness of the proposed method with the experimental results. © 2022 IEEE.

Correctly capturing intraoperative brain shift in image-guided neurosurgical procedures is a critical task for aligning preoperative data with intraoperative geometry for ensuring accurate surgical navigation. While the finite element method (FEM) is a proven technique to effectively approximate soft tissue deformation through biomechanical formulations, their degree of success boils down to a trade-off between accuracy and speed. To circumvent this problem, the most recent works in this domain have proposed leveraging data-driven models obtained by training various machine learning algorithms-e.g., random forests, artificial neural networks (ANNs)-with the results of finite element analysis (FEA) to speed up tissue deformation approximations by prediction. These methods, however, do not account for the structure of the finite element (FE) mesh during training that provides information on node connectivities as well as the distance between them, which can aid with approximating tissue deformation based on the proximity of force load points with the rest of the mesh nodes. Therefore, this work proposes a novel framework, PhysGNN, a data-driven model that approximates the solution of the FEM by leveraging graph neural networks (GNNs), which are capable of accounting for the mesh structural information and inductive learning over unstructured grids and complex topological structures. Empirically, we demonstrate that the proposed architecture, PhysGNN, promises accurate and fast soft tissue deformation approximations, and is competitive with the state-of-the-art (SOTA) algorithms while promising enhanced computational feasibility, therefore suitable for neurosurgical settings.
