In this paper, an adaptive fractional-order optical flow selection algorithm with improved ant colony clustering is proposed to address the issues of texture processing and dynamic noise perturbation in simultaneous localization and mapping algorithms in dynamic scenes with strong static assumption theory. The algorithm combines the characteristics of fractional differentiation and sparse optical flow algorithm, and makes full use of the weak texture gradient of the image. The ant colony algorithm is improved by using the elite sharing mechanism, and the improved ant colony algorithm is combined with the clustering algorithm. The experimental results show that the algorithm not only realizes the adaptive selection of the best order, but also achieves better dynamic disturbance differentiation ability through the clustering of feature selection. While distinguishing dynamic and static information effectively, more details of optical flow with weak gradient feature are preserved. The proposed algorithm holds promise for simultaneous localization and mapping systems.

Advancements in artificial intelligence ( AI) have driven a s hift toward disaggregated computing infrastructures, integrating optical technologies in data centers to enhance data transfer. As data centers evolve into hybrid opto-electronic systems, we explore the potential of optics for computational tasks such as matrix-vector multiplication (MVM). Various proposals and demonstrations of optical MVM have been reported, with some 3D opticalsystems demonstrating notable scalability advantages. However, the predominant systems primarily utilize space multiplexing, leaving the frequency dimension underexploited. In this talk, we introduce a hyperspectral compute-in-memory (CIM) architecture that simultaneously utilizes frequency and space dimensions for single-shot matrix-matrix multiplication (MMM). We will overview the system architecture, discuss the design of key components, and address the use of chip-integrated optical elements such as micro-combs and photonic interposers. The architecture offers remarkable parallelism, s calability, programmability, and efficient chip area use, enabling high computational throughput with a compute density greater than Peta operation per second (PetaOPS/mm(2)). Our work shows potential for energy-efficient, three-dimensional opto-electronic computing in future data center applications.

Nanophotonic structures have versatile applications including solar cells, anti-reflective coatings, electromagnetic interference shielding, optical filters, and light emitting diodes. To design and understand these nanophotonic structures, electrodynamic simulations are essential. These simulations enable us to model electromagnetic fields over time and calculate optical properties. In this work, we introduce frameworks and benchmarks to evaluate nanophotonic structures in the context of parametric structure design problems. The benchmarks are instrumental in assessing the performance of optimization algorithms and identifying an optimal structure based on target optical properties. Moreover, we explore the impact of varying grid sizes in electrodynamic simulations, shedding light on how evaluation fidelity can be strategically leveraged in enhancing structure designs.

The Yellow River Delta (YRD) wetlands are the largest coastal wetlands in China, and it serves to control soil erosion, nourish the climate and protect biodiversity. At present, due to climate change and human activities, the wetlands of the YRD are facing ecological and environmental problems such as species invasion, vegetation degradation, and biodiversity reduction. In order to study the evolution of wetland landscape types more intuitively, this paper proposed a semantic segmentation network based on the encoder and decoder structure of ResNet-18. Then, the wetland landscapes in the YRD were classified into five types by combining the Landsat series of remote sensing images. In addition, this paper used the optical flow algorithm to visualize the identification results, which can represent the evolution pattern of wetland landscape types in different years. The results of this paper have an important significance for the subsequent development planning and protection in the YRD.

This research paper introduces a Rule-Based Expert System designed for the automated editing of documents in PDF and PPT formats. The system employs a set of predefined rules, extracted from guideline documents using a Large Language Model (LLM), to execute tasks such as redaction of sensitive text/logo detection and annotation of text elements that deviate from prescribed font size guidelines. Following the detection and annotation process, the system further enhances documents by resizing the detected text elements based on the predefined rules. To achieve these editing tasks, the system integrates advanced image processing techniques, leveraging fine-tuned optical Character Recognition (OCR) for accurate text extraction from document images. Furthermore, Natural Language processing (NLP) algorithms are utilized to analyze and interpret textual content. The combination of image processing, OCR, NLP, and rule extraction using LLM ensures a comprehensive approach to document editing, enhancing efficiency and accuracy. The proposed system addresses the need for automated and rule-driven document editing, contributing to advancements in information security and document standardization.
