The key to threshold segmentation is choosing the thresholds that will decide the segmentation's outcome-the calculation complexity increases as the number of thresholds increases, which causes challenges with traditional methods. This study introduces an enhanced bats algorithm (EBA) for selecting optimal picture segmentation thresholds and applies it to the global optimization issue of the segmentation function's objective function. The EBA blends well with picture segmentation that produces exceptional computation in global convergence and robustness and prevents trapping into local optimization. It is particularly well suited to solving complex functions with high dimensions and multiple peaks. Compared to GA and PSO, extensive theoretical study and simulation results reveal that EBA has greater efficacy, efficiency, stability of the range of thresholds, and quality in multi-image and multi-thresholds segmentation.

~ Advances in immunological research are essential for elucidating immune responses and developing targeted therapeutic approaches. This study proposes an automated method for immune cell classification leveraging machine learning and image processing techniques. A novel framework is introduced, combining high-resolution imaging with computational algorithms to accurately classify various immune cell types from biological samples. The methodology incorporated pre-processing steps, like normalization and noise reduction. Then, deep learning models, such as CNNs and SVMs, will be applied for feature extraction and classification. These models were trained on annotated datasets derived from flow cytometry and microscopy, demonstrating better accuracy and reliability. Results demonstrate an improvement in processing speed and accuracy of classification over traditional approaches, which underlines the importance of automation in immunological diagnostics. The data obtained can be used in high-throughput immunotherapy and disease diagnostic screening; it allows for the identification of immune cell populations within a short period and therefore improves research efficiency. The work provides a basis for real-time analysis and incorporation of multiscale datasets that will help to better understand immunity and its associated disorders.

Traffic has been a major problem in recent times. Traffic management is a must for safer and faster transportation. Automatic smart signal controlling systems respond to day-to-day world traffic densities to provide precedence and reduction in cross-road delays for travelers. According to the traffic density, the time between signals is adjusted so that the waiting time in traffic reduces. The ML model is capable of detecting accidents and immediately sends notifications or alert messages to nearby hospitals. The model tracks the GPS location of the ambulance and ensures no red signal in its pathway. Zebra crossing signals are also included, the signal timings are switched based on the crossing crowd. Automatic Smart Signal Control is a complete Machine Learning based project with some applications of IoT and Video / image processing. Implementation of the model all over the major signals and junctions provides faster and safer transportation. © 2022 IEEE.

Diabetic Retinopathy has been one of the common reason why diabetic patients lose sight. It is caused by the damaging of the blood vessel of the light sensitive tissue at the back of the eye or the retina. The traditional methods for the detection of the disease requires lots of time and efforts hence the proposed system aims to detect diabetic retinopathy using image processing and Machine Learning. The input provided to the proposed system are the retinal images from the standard databases DIARETDB0 and DIARETDB1. The system aims to automate the process of detection using a combination of basic image processing steps with more focus on pre-processing to obtain clear image for feature extraction, further Machine Learning algorithms are applied for classification. The statistical features such as area and perimeter are obtained from blood vessels and exudates after pre-processing stage, different pre-processing techniques such as grayscale conversion, binarization, canny edge detection and some morphological operations including image dilation and erosion are applied to obtain clear image. The Machine Learning algorithms that are used for result analysis are Weighted KNN, Cubic SVM and Simple Tree which provides an accuracy of 85.8%, 87.2% and 88.6% respectively. The sensitivity and specificity parameters are also obtained, Simple tree yields better results for all the three result parameters.

The paper aims to explore the application effects of deep learning algorithms in sports image recognition and analysis. Faced with the challenges of insufficient feature extraction ability in the field of sports image recognition. This article proposes a fusion algorithm based on CNN-GCN (Convolutional Neural Network Graph Convolutional Network). Through in-depth analysis of previous research achievements and challenges encountered, this article not only points out the limitations of traditional methods, but also demonstrates how deep learning technology effectively solves these problems. In the experimental section, it evaluated the performance of the CNN-GCN fusion algorithm and Support Vector Machine (SVM), Random Forest (RF) algorithm, and Multi-Layer Perceptron (MLP) algorithm in sports image recognition and analysis tasks through four different experiments. In the benchmark performance comparison experiment, the CNN-GCN fusion algorithm achieved an accuracy of 93%, and achieved recall, precision, and F1 scores of 91%, 92%, and 91.5%, respectively, all higher than other reference algorithms. In the robustness testing experiment, in the face of degraded image quality, the accuracy of CNN-GCN can also be maintained at 85%, significantly higher than the performance of SVM, RF, and MLP algorithms under the same conditions. In the experiment of dynamic scene analysis capability, the CNN-GCN fusion algorithm achieved an accuracy of 85% when dealing with high complexity dynamic scenes. In the final real-time processing capability evaluation, the CNN-GCN fusion algorithm also took the lead with a processing time of 25 milliseconds. In the data conclusion of the above experiment, the CNN-GCN fusion algorithm has shown excellent performance in the field of sports image recognition and analysis, and also reflects the enormous potential of the CNN-GCN fusion algorithm in real-time application scenarios.

image caption is textual explanation automatically generated by a computer according to the content in an image. It involves both image and natural language processing, and thus becomes an important research topic in pattern recognition. Deep learning has been successful in accomplishing this task, and the quality of captions generated by existing methods is already high. However, due to the broadness and variety of image caption applications, the current generated captions are still not sufficiently detailed, and the training efficiency can also be improved. Therefore, under the encoder-decoder framework of deep learning, how to use fewer parameters to improve the training efficiency and retain the quality of the generated image descriptions is a huge challenge. In this work, we introduce an improved method based on the encoder-decoder structure, adding an attention mechanism, and applying the content adaptive recurrent unit (CARU), as the decoder, to generate image captions. Inspired by GRU, CARU is designed to have comparable performance with fewer parameters, and is sensitive to the features in hidden layers. The experimental results show, based on MsCOCO dataset, the proposed method achieved better performance than that using GRU as the decoder, and took less training time, effectively improves the training efficiency.

Digital holography (DH) is an imaging technique that allows the recording and the reconstruction of the complex optical field (complete information) in both amplitude and phase. Its main advantage is the possibility to modify the recorded wavefront to get free-aberration version. This technique represents the best contender for metrological applications especially in mechanical fluids where it gives an additional dimension for the determination of velocity field of different kind of fluid flow. In order to extend the fluid field of investigation, two synchronized cameras CCD and CMOS with different characteristic (pitch and size) are used for recording two views holograms; this task is implemented under Labview interface which also permits to record successive several holograms with a predefined time interval. The holograms are obtained with the help of holographic setup in off-axis configuration of two views (direct and orthogonal). In order to obtain the total field of view, the two reconstructed holograms must have the same output resolution.

In colleges and universities in China, physical education is a crucial public fundamental subject. Traditional instruction often takes place during the designated class period in the training program. The instructor imparts to the pupils the principles of physical education so that they may become proficient in sports and ultimately raise their physical and athletic abilities. To lessen the issue of the basic genetic algorithm for intelligent grouping systems' delayed convergence and partial convergence, an enhanced genetic algorithm is suggested. By consistently rejecting comparable candidates, the algorithm may quickly expand the search field and guarantee the stability and diversity of the group. As a result, this work suggests a novel approach to intelligent grouping that is based on an enhanced genetic algorithm. Compared to the conventional algorithm, the novel approach is more effective and straightforward in resolving the issue of the algorithm's early convergence. Numerous tests have demonstrated how effectively the suggested algorithm satisfies every need for physical education. Test papers with a moderate level of difficulty and a sensible structure can be automatically generated by the genetic algorithm.
