COMPrompter: reconceptualized segment anything model with multiprompt network for camouflaged object detection

引用

Science China(Information Sciences) 2025年第1期68卷 189-203页

作者： Xiaoqin ZHANG Zhenni YU Li zhao Deng-ping FAN Guobao XIAO Zhejiang Province Key Laboratory of Intelligent Informatics for Safety and Emergency Wenzhou University Nankai International Advanced Research Institute (SHENZHEN FUTIAN) College of Computer Science Nankai University School of Computer Science and Technology Tongji University

We rethink the segment anything model(SAM) and propose a novel multiprompt network called COMPrompter for camouflaged object detection(COD). SAM has zero-shot generalization ability beyond other models and can provide an ideal framework for COD. Our network aims to enhance the single prompt strategy in SAM to a multiprompt strategy. To achieve this, we propose an edge gradient extraction module, which generates a mask containing gradient information regarding the boundaries of camouflaged objects. This gradient mask is then used as a novel boundary prompt, enhancing the segmentation process. Thereafter, we design a box-boundary mutual guidance module, which fosters more precise and comprehensive feature extraction via mutual guidance between a boundary prompt and a box prompt. This collaboration enhances the model's ability to accurately detect camouflaged objects. Moreover, we employ the discrete wavelet transform to extract high-frequency features from image embeddings. The high-frequency features serve as a supplementary component to the multiprompt ***, our COMPrompter guides the network to achieve enhanced segmentation results, thereby advancing the development of SAM in terms of COD. Experimental results across COD benchmarks demonstrate that COMPrompter achieves a cutting-edge performance, surpassing the current leading model by an average positive metric of 2.2% in COD10K. In the specific application of COD, the experimental results in polyp segmentation show that our model is superior to top-tier methods as well. The code will be made available at https://***/guobaoxiao/COMPrompter.

Over the years,the high magnetic induction of industrial Mn-added electrical steel is assumed to be the enhancement of{100}texture derived from its austenite-ferrite phase transformation during hot rolling(phase transformation(PT)method).However,it is still undetermined without straightforward experimental *** reason for{100}texture improvement of Mn-added electrical steel is experimentally confirmed due to the recrystallization induced by the austenite-ferrite phase transformation during hot ***,a more promising methodology to further improve{100}texture and formability of hot-rolled electrical steel is promoted by the control of hot rolling deformation condition(shear deformation(SD)method).The results show that the nucleation mechanisms of{100}oriented recrystallized grains are different in the samples by SD and PT methods,which are in-depth shear deformation and austenite-ferrite phase transformation,*** this case,coarse{100}oriented recrystallized grains and low residual stress are obtained in the sample by SD method,which is responsible for its superior{100}texture and *** contrast,the sample by PT method forms fine recrystallized grains with random orientations and accumulates severe residual stress.

Emerging organic carbonyl small molecules cathode materials in alkali-ion batteries: Principles, recent progresses, strategies and prospects

Progress in Natural Science:Materials International 2025年第01期 31-50页

作者： Suping Chen Xijun Xu Tao Yang Weizhen Fan Jingwei zhao Yanping huo School of Chemical Engineering and Light Industry Guangdong University of Technology Guangdong Provincial Laboratory of Chemistry and Fine Chemical Engineering Jieyang Center Research and Development Center Guangzhou Tinci Materials Technology Co. Ltd. Analytical&Testing Center Guangdong University of Technology

Carbonyl small molecule compounds hold great potential as cathode materials for alkali-ion batteries（AIBs） due to their environmental friendliness, structural designability, and high theoretical capacity. However, it's practical application is hindered by intrinsic drawbacks, such as low electrical conductivity and high solubility in organic electrolytes. Additionally, most carbonyl small molecule cathodes can't be charged first in half-cells due to the absence of detachable Li+/Na+/K+ions, diminishing their appeal when assembled into full cells with alkali-free anodes. This review provides a detailed overview of carbonyl-contained small molecule cathode materials centered around oxygen, including their charge storage mechanisms, solutions to overcome their drawbacks, and the latest research advancements in AIBs. This review also summarizes the electrochemical performance of carbonyl small molecules as cathodes that have been assembled in batteries. Finally, the review outlines the prospects and directions for future research on carbonyl small molecule cathodes. It is hoped that this review will offer meaningful guidance for the development of carbonyl small-molecule cathode materials in AIBs.
