However, the former method usually suffers from the conflict between detection and association due to the semantic ambiguity between tracking and detection instances in joint training, resulting in unsatisfactory performance compared to the latter method. Previous tracking-by-query methods usually use an extra detector to decouple the detection and association tasks. However, these methods inevitably introduce complex operations like additional detectors or manual hyperparameters adjustment.

Specifically, a Query Boostarpping module is designed to enhance the semantic features of the tracking query in order to distinguish the detection and tracking instances. This module integrates both positional and specific semantic information into the tracker effectively while maintaining the simple pipeline of the whole network. The tracking performance of various MOT networks is evaluated on multiple datasets. Evaluation results demonstrate that QB-MOTR surpasses baseline method MOTR by about 18.1%.

Most industrial anomaly detection methods assume the availability of sufficient normal data for training. This assumption may not hold true due to the cost of labeling or data privacy policies. Additionally, mainstream methods require training bespoke models for different objects, which incurs heavy costs and lacks flexibility in practice. To address these issues, in this paper, we for the first time propose to leverage the pretrained generative model, Stable Diffusion (SD), to perform the one-for-all few-shot anomaly detection task, in contrast to existing few-shot anomaly detection works that heavily rely on the use of pre-trained representation-based CLIP model. To adapt SD to anomaly detection task, we design different hierarchical text descriptions and the foreground mask mechanism for fine-tuning the SD. At the testing stage, to accurately mask anomalous regions for inpainting, we propose a multi-scale mask strategy and prototype-guided mask strategy to handle diverse anomalous regions. Hierarchical text prompts are also utilized to guide the process of inpainting in the inference stage. Extensive experiments on the MVTec-AD and VisA datasets demonstrate the superiority of our approach. We achieved anomaly classification and segmentation results of 93.6%/94.8% AUROC on the MVTec-AD dataset and 86.1%/96.5% AUROC on the VisA dataset under multi-class and one-shot settings.

To address this problem, we propose the Workplace Hazards Dataset (WHD), a balanced and diverse set of real-world videos representing five universal hazard categories in varied workplace settings.

In this paper, we draw on considerations about image style and content from the style transfer task, and believe that the degradation of hazy images typically involves the transition of style and the hiding of details, and then the image dehazing task can be divided and conquered according to the two aspects to reduce the learning difficulty of the dehazing network for effective image dehazing. Based on this inspiration, in this paper, we propose an image dehazing network with a specific focus on style recovery and detail replenishment, namely SRDR, which firstly recovers the style and extracts the detail of the hazy image, respectively, and then aggregates the information from style recovery and detail replenishment for better image dehazing. The SRDR mainly consists of three modules: Style Recovery Module (SRM), Detail Replenishment Module (DRM), and Cross Fusion Module (CFM). SRM is responsible for style recovery by adapting the pre-trained MAE model, DRM handles the detail replenishment with multiple direction convolutions, and CFM is an information aggregation module.

Key developments such as Vision Transformers, self-supervised learning, and multi-modal learning have significantly contributed to the advancement of VFMs. However, these models face challenges, including high resource demands, weak locality, and a lack of generalized features. Drawing inspiration from the human brain’s ability to emphasize important information while suppressing irrelevant input, local mechanisms have been designed to address these challenges and enhance VFMs development. Local mechanisms not only focus on specific parts of an input to learn discriminative, fine-grained features but also selectively process information, thereby improving model efficiency. These mechanisms exhibit unique characteristics across different domains. In this survey, we provide a systematic review of local mechanisms across three key areas of VFMs: multi-modal learning, self-supervised learning, and Vision Transformers. We categorize the various local mechanisms, summarize quantitative results in each area, and analyze the advantages and disadvantages of each category in depth, offering insights for further exploration. We examine the potential of VFMs in semi-supervised learning, weakly supervised learning, domain adaptation, and few-shot learning, highlighting their specific applications in remote sensing and medical image analysis.
