Wildfire monitoring systems play a critical role in minimizing environmental and societal damage. Recent advances in computer vision, particularly deep learning-based fire detection, have enabled more accurate and scalable solutions. However, conventional fire detection methods often struggle with wildfire scenarios due to wide spatial extent, the demand for precise localization, and the urgency of early response. To overcome these challenges, we propose a wildfire monitoring framework capable of pixel-level fire origin localization mapped onto a GPS-calibrated digital twin of mountainous terrain. Our system integrates visual fire detection with terrain-aware 3D projection, enabling accurate mapping of fire origins to real-world coordinates. Experimental results on wildfire datasets demonstrate that our method achieves high accuracy in both early fire detection and precise localization, offering a practical and scalable solution for real-world wildfire monitoring.

Retrieving the target vehicle through natural language descriptions plays a crucial role in intelligent transportation systems. Existing methods tackle this task by employing models that leverage the correlation between textual and visual representations, such as CLIP. However, these models struggle to capture the temporal characteristics of video data, and researchers enhance temporal understanding performance through various data augmentation and video encoders. Yet, conventional approaches in previous studies often overlook the detailed temporal characteristics of vehicles. To overcome this limitation, we introduce a MOVES: Motion-Oriented VidEo Sampling method to effectively utilize the motion information of the target vehicle. Furthermore, we construct a robust model by implementing a re-ranking algorithm to address a variety of vehicle attributes. As a result, our proposed model achieves state-of-the-art performance on the public vehicle retrieval dataset.

Person Re-IDentification (ReID) is a pivotal method for pedestrian tracking and retrieval. This research is inherently challenged by large changes in intra-class or small changes in inter-class. To address this challenge, many researchers have recently introduced transformer-based models, which have shown excellent results. The primary objective of these models is to generate robust features that effectively distinguish between classes and enable generalization. However, existing methods still suffer from class discrimination due to unnecessary noise, including the background. To overcome this limitation, we propose a novel approach called Two stream-based Regionally Enhanced Transformers (TRET) that focuses on the target to be identified. To concentrate on the target region, the TRET utilizes a structure that leverages the pedestrian mask. Furthermore, the proposed model generalizes well by utilizing Contrastive Language-Image Pretraining as the backbone. Finally, our proposed model achieves state-of-the-art performance on the public datasets.

Person re-identification (ReID) plays a significant role in intelligent surveillance systems. However, it is challenging due to large variations in the intra-class, where the same person is captured in different scenes or cameras. The current person ReID research focuses on creating robust features for class distinction and generalizing neural networks for covering various target domains to address the issue. Recently, after the achievement of vision transformers, the application of transformers has also begun to person ReID studies. The transformer-based methods have improved quantitative performance of person ReID; however, they still suffer from class distinction. Therefore, this paper proposes a novel region-enhanced transformer (REET) to create robust ReID features. Unlike conventional transformer-based approaches, the REET emphasizes the tokens generated by region-level. Our method achieves state-of-the-art results on three public datasets; Market1501, DukeMTMC, and CUHK-03.

Gait recognition, which refers to the recognition or identification of a person based on their body shape and walking styles, derived from video data captured from a distance, is widely used in crime prevention, forensic identification, and social security. However, to the best of our knowledge, most of the existing methods use appearance, posture and temporal feautures without considering a learned temporal attention mechanism for global and local information fusion. In this paper, we propose a novel gait recognition framework, called Temporal Attention and Keypoint-guided Embedding (GaitTAKE), which effectively fuses temporal-attention-based global and local appearance feature and temporal aggregated human pose feature. Experimental results show that our proposed method achieves a new SOTA in gait recognition with rank-1 accuracy of 98.0% (normal), 97.5% (bag) and 92.2% (coat) on the CASIA-B gait dataset; 90.4% accuracy on the OU-MVLP gait dataset.

The Radar Object Detection 2021 (ROD2021) Challenge, held in the ACM International Conference on Multimedia Retrieval (ICMR) 2021, has been introduced to detect and classify objects purely using an FMCW radar for autonomous driving applications. As a robust sensor to all-weather conditions, radar has rich information hidden in the radio frequencies, which can potentially achieve object detection and classification. This insight will provide a new object perception solution for an autonomous vehicle even in adverse driving scenarios. The ROD2021 Challenge is the first public benchmark focusing on this topic, which attracts great attention and participation. There are more than 260 participants among 37 teams from more than 10 countries with different academic and industrial affiliations, contributing about 300 submissions in the first phase and 400 submissions in the second phase. The final performance is evaluated by average precision (AP). Results add strong value and a better understanding of the radar object detection task for the autonomous vehicle community.

In this paper, we propose a novel framework for multi-target multi-camera tracking (MTMCT) of vehicles based on metadata-aided re-identification (MA-ReID) and the trajectory-based camera link model (TCLM). Given a video sequence and the corresponding frame-by-frame vehicle detections, we first address the isolated tracklets issue from single camera tracking (SCT) by the proposed traffic-aware single-camera tracking (TSCT). Then, after automatically constructing the TCLM, we solve MTMCT by the MA-ReID. The TCLM is generated from camera topological configuration to obtain the spatial and temporal information to improve the performance of MTMCT by reducing the candidate search of ReID. We also use the temporal attention model to create more discriminative embeddings of trajectories from each camera to achieve robust distance measures for vehicle ReID. Moreover, we train a metadata classifier for MTMCT to obtain the metadata feature, which is concatenated with the temporal attention based embeddings. Finally, the TCLM and hierarchical clustering are jointly applied for global ID assignment. The proposed method is evaluated on the CityFlow dataset, achieving IDF1 76.77%, which outperforms the state-of-the-art MTMCT methods.

Colorectal cancer (CRC) is the development of cancer from the colon or rectum. Microsatellite instability (MSI) status can be considered as an indicator to predict the prognosis of CRC. We employ MSI prediction of CRC image by designing a neural network model of which base network is DeepLabv3+ with OctaveResNet. Additionally, we add a channel sort module to divide a feature map along with channel intensity. Then each feature map goes through distinct convolution paths. Each convolution path is designed based on information theory: the most important feature goes through the lightest convolution path, vice versa. By dividing feature map and applying different amount of convolutional operation, the model can extract features efficiently. In the experiment, total model weight is reduced but accuracy increases.

In recent years, vision-based object detection methods using convolutional neural network (CNN) have been very successful. However, the object detection method using the CNN feature has a disadvantage that lots of feature maps should be generated in order to be robust against the scale change and the occlusion of the object. Also, simply raising a large number of feature maps does not improve performance. We propose a multi-scale vehicle detection with spatial pyramid pooling method which is robust to the scale change of the vehicle and the occlusion by improving the conventional YOLOv3 algorithm. The proposed method was evaluated through the UA-DETRAC benchmark and obtain the state-of-the-art mAP, which is better than those of the DPM, ACF, R-CNN, CompACT, NANO, SA-FRCNN, and Faster-RCNN2.

A desirable smart traffic-monitoring and street-safety system can elicit and support the intervention of law enforcement agencies or medical staff. Recently, there has been a dramatically higher demand for such smart systems. To this end, the International Workshop on Traffic and Street Surveillance for Safety and Security (IWT4S) was organized in conjunction with the 15th IEEE International Conference on Advanced Video and Signal-based Surveillance (AVSS 2018). Our goal is to advance the state-of-the-art detection and tracking algorithms and provide a comprehensive performance evaluation for them. We evaluate 5 submitted detection and 7 submitted tracking methods on the large-scale UA-DETRAC benchmark, and the results are shared publicly on the website http://detrac-db. rit.albany.edu. We expect this challenge to advance the research and development of new detection and tracking methods for transportation applications.
