Efficient image processing architectures are consistently in demand across a multitude of applications, particularly those customized for resource-constrained systems-on-chip (SoC). The increasing need for high-performance image processing in various sectors has driven the development of specialized architectures. However, deploying such architectures on platforms with limited resources, such as SoCs, poses significant challenges. Furthermore, the implementation of complex algorithms to handle large datasets using software solutions often leads to slower response times, prompting exploration into hardware implementations. Field-Programmable Gate Arrays (FPGAs) are becoming popular for hardware implementations because of their attributes: low latency, connectivity, parallel computing capabilities, and flexibility. Consequently, the utilization of FPGA-based implementations has resulted in faster and more efficient performance of unique architectures tailored to specific requirements. This paper presents a novel hardware/software co-design approach to implement erosion, dilation, and neighborhood image processing operations on the FPGA development board, "Zedboard". In this approach, the FPGA is programmed by connecting it to a PC via USB, facilitating the transfer of an image pixel by pixel. The pixels are temporarily stored in on-chip DDR and accessed through DMA (Direct Memory Access) until they are requested by an interrupt signal from the Image Processing IP, at which point they are moved to line buffers for faster processing. Once processed, the image is transmitted back to the PC via UART, facilitating pixel-by-pixel transfer for verification, where it is compared with a reference image generated using Python. This comparison confirms a 99.22% match between the processed image and the reference image, with the discrepancy occurring at the image's edges due to initial padding. Additionally, the time required to process the entire image was measured and displayed

Metro is one of the most important forms of public transportation in Chinese cities. With the continuous expansion and development of metro networks in China's major cities, ensuring the safety of passengers has become a key part of metro operation and management. However, there are some efficiency and human factors engineering deficiencies in the current metro security system. Some researchers have studied the efficiency of subway security systems and their influencing factors in subway or railroad stations. However, in actual subway stations, the spatial guidance in front of and behind the screening area is also one of the causes of congestion in the screening area. This study focuses on the deficiencies of spatial guidance in the subway, and the resulting congestion in the subway station, which leads to a reduction in the efficiency of the screening system. The implementation plan of this study is to explore the spatial guidance system of Guangzhou Metro, summarize the influencing factors of congestion, quantify and extract data for the influencing factors, and establish a model and data analysis. The interview method was used to invite volunteers to participate, and the information from the interviews was used for data statistics to quantify the influencing factors caused by the spatial guidance system, to establish an appropriate model for the influencing factors, and to determine the significant influencing factors of the spatial guidance on the congestion of people with respect to the data fed back from the model. The collected data and information are coded using the rooted theory research method, analyzed with the help of auxiliary software, and finally, three categories of first-level core influence factors of site layout design, guide signs, and human factors and corresponding second- and third-level subcategories are refined, and a system of influence factors on the efficiency of the process of the security system under the perspective of spatial guidanc

Reactive synthesis is an automated procedure to obtain a correct-by-construction reactive system from its temporal logic specification. While the synthesized system is guaranteed to be correct w.r.t. the specification, the specification itself may be incorrect w.r.t. the engineers' intention or w.r.t. the requirements or the environment in which the system should execute in. It thus requires validation. Combinatorial coverage (CC) is a well-known coverage criterion. Its rationale and key for effectiveness is the empirical observation that in many cases, the presence of a defect depends on the interaction between a small number of features of the system at hand. In this work we propose a validation approach for a reactive system specification, based on a systematic combinatorial exploration of the behaviors of a controller that was synthesized from it. Specifically, we present an algorithm to generate and execute a small scenario suite that covers all tuples of given variable value combinations over the reachable states of the controller. We have implemented our work in the Spectra synthesis environment. We evaluated it over benchmarks from the literature using a mutation approach, specifically tailored for evaluating scenario suites of temporal specifications for reactive synthesis. The evaluation shows that for pairwise coverage, our CC algorithms are feasible and provide a 1.7 factor of improvement in mutation score compared to random scenario generation. We further report on a user study with students who have participated in a workshop class at our university and have used our tool to validate their specifications. The user study results demonstrate the potential effectiveness of our work in helping engineers detect real bugs in the specifications they write.

The task of object detection is widely recognised as a prominent challenge in computer vision applications, particularly in the domains of robotics, autonomous vehicles, and augmented reality. Hence, this paper examines Faster RCNN, a well embraced object identification model that effectively combines speed and accuracy. The authors evaluate several novel models, such as Sparse R-CNN, Cascade R-CNN, Loss-Guided Attention RCNN, Global Context Aggregation RCNN, and others, to demonstrate their unique features and benefits in addressing the challenges of dense object candidates and limited training data. This paper presents a performance evaluation of these models on the COCO dataset, elucidating their accuracy and usefulness for different object detecting applications. The authors conclude that the Sparse R-CNN model outperforms other models in terms of average precision. They also offer recommendations for future optimisation of object identification models in terms of architecture to better suit the demands of real-time processing.
