Low-resolution image object recognition and tracking is often required for battlefield reconnaissance. For high-cost military systems, standard signal processing techniques can be used by tracking systems, however, low-cost systems require simpler approaches. We developed a fast detector-agnostic tracker for improving situational awareness using electro-optical video data. Our approach uses low computational techniques such as YOLO, match filters, and shape transforms to segment objects of interest in an image. From two or more successive detections, we initialize an alphabeta filter that predicts the location of the target of interest in the image. Next, we segment subsequent frames to a search area around the predicted region. This increases the sensitivity of the detector by improving the average signal-to-noise ratio and it also decreases the false alarm rate. The reduction in the size of the processing area can improve the detection speed per frame by an order of magnitude relative to a full-sized frame. By using algorithms with input from variablesize object a such as YOLO, this algorithm can be adapted to track virtually any object captured in a video.

In the realm of Printed Circuit Board (PCB) manufacturing, the alignment process is pivotal for ensuring the functional integrity of the final product. Traditional image measurement techniques, while foundational, often fall short of achieving the high degree of accuracy and precision necessary for today's complex PCB designs. This research presents a novel approach that significantly enhances measurement accuracy through the application of optimized imageprocessing techniques. By leveraging advanced algorithms within the OpenCV library, we introduce a methodology that accurately transforms pixel coordinates into real-world measurements, crucial for precise PCB alignment. Our technique employs edge detection algorithms such as Canny, Sobel, and Prewit filters, combined with a machine learning model that adapts to variations in real-time imaging conditions. The study delineates the development of a user-friendly graphical interface that streamlines the measurement process, making it accessible for practical industrial application. Results from experimental validations indicate a substantial improvement in measurement precision, with a demonstrable reduction in alignment errors compared to conventional methods. This leap forward not only promises to elevate the standards of PCB manufacturing but also opens avenues for similar advancements in other domains where image measurement is essential. The implications of this work are far-reaching, with the potential to significantly boost the efficiency and reliability of electronic manufacturing processes globally.

GPU as a hardware processor plays an important role in the training of deep neural networks. However, when using GPUs for computation on convolutional neural network models, different combinations of GPU kernel configuration parameters have different performance. Therefore, this paper proposes BAGF, a bayesian auto-tuning framework for GPU kernels, which parameterizes the factors affecting the performance of GPU programs and uses bayesian optimization methods to search for the best parameters in the search space consisting of the parameters. Compared with other optimization algorithms, BAGF obtains excellent configuration parameters with fewer iterations. This paper analyzes the performance of BAGF on four benchmarks and compares with other common optimization algorithms. In addition, the performance improvement of each parameter configuration is analyzed. Finally, the BAGF was tested with the convolution layer of Alexnet, and the results of the Roofline model were analyzed. Compared with the original parameter configuration, the speed of BAGF was increased by 50.09%.
In this study, we comprehensively examine the potential of deep learning algorithms in the domain of medical imageprocessing. Through a systematic analysis of existing literature, we explore the applications, methodo...
