However, labeling such points for supervised learning tasks is time-consuming. As a result, there is a need to investigate techniques that can learn from unlabeled data to significantly reduce the number of annotated samples. In this work, we propose to train a self-supervised encoder with Barlow Twins and use it as a pre-trained network in the task of semantic scene segmentation. The experimental results demonstrate that our unsupervised pre-training boosts performance once fine-tuned on the supervised task, especially for under-represented categories.","PeriodicalId":338734,"journal":{"name":"2023 18th International Conference on Machine Vision and Applications (MVA)","volume":"106 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115157357","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the task of delineating the boundary of volcanic eruptions becomes difficult due to non-uniformity in the scale of eruptions across remote sensing images. In this paper, we propose a network for multi-scale volcanic ash clouds segmentation (MS-VACSNet) in remote sensing images. The proposed MS-VACSNet uses U-Net as base line with few improvements in the encoder and decoder sub-networks. Specifically, we employ dilated convolutions to capture the contextual information while delineating volcanic eruptions of different scales. We have conducted experiments on 10 active volcanic regions across the globe using MODIS thermal and infrared images. The experimental results show that our MS-VACSNet achieves an improvement of 5% in dice score compared to state-of-the-art segmentation approaches in segmenting the volcanic ash clouds.","PeriodicalId":338734,"journal":{"name":"2023 18th International Conference on Machine Vision and Applications (MVA)","volume":"162 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124211786","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This work proposes a novel real-time solar now-casting methodology for solar irradiance prediction based on deep transfer learning from ground-based sky imagery. Existing approaches use statistical methods or Convolutional Neural Networks for irradiation regression trained for a particular location that cannot be transferred to new locations deploying potentially different imaging sensors. This observation motivated us to introduce a large deep neural network based on Vision Transformers that is generalizable and transferable to different scenarios.The system is developed using multiple years of solar irradiance and sky image recordings in two locations. We captured our own data set in Princeton, NJ, USA and also used open-source ASI16 benchmark dataset captured in Golden, CO, USA. The method is validated against these two locations of diverse geographic, climatic conditions and sensor variation. Results show that the proposed method is robust and highly accurate (85-90% accuracy) for multiple locations deployment with 50% less data requirement from new locations.","PeriodicalId":338734,"journal":{"name":"2023 18th International Conference on Machine Vision and Applications (MVA)","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132646861","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

RTW is a general extension of Dynamic Time Warping (DTW), widely used for matching and comparing sequential patterns. The basic idea of RTW is to simultaneously calculate the similarities between many pairs of various warped patterns, i.e. Time elastic (TE) features generated by randomly sampling the sequential pattern while retaining their temporal order. This mechanism enables RTW to treat the changes in motion speed flexibly. However, naive TE feature vectors generated from raw images are not expected to have high discriminative power. Besides, the dimension of TE features can increase depending on the number of concatenated images. To address the limitations, we incorporate CNN features extracted from 2D/3D CNNs into the framework of RTW as input to address this issue. Our framework is very simple but effective and applicable to various types of CNN architecture. Extensive experiment on public motion datasets, Jester and Something-Something V2, supports the advantage of our method over the original CNNs.","PeriodicalId":338734,"journal":{"name":"2023 18th International Conference on Machine Vision and Applications (MVA)","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134554458","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Early diagnosis and proper treatment even for the deadliest malignant melanoma can greatly increase the survival rate. Thus, computer-aided diagnosis for skin lesions has been actively explored and made remarkable progress in medical practices benefiting from the the great advance of the deep convolution neural networks in vision tasks. However, most studies in skin lesion/cancer recognition and detection focus on reconstructing a robust prediction model with the annotated training samples in a fully-supervised manner, and cannot make full use of the available unlabeled data. This study investigates self-supervised learning using large amount of unlabeled skin lesion images to train a good initial network for representation learning, and transfer the knowledge of the initial model to the supervised skin lesion classification task with small number of annotated samples for enhancing the performance. Specifically, we employ a negative sample-free self-supervised framework by leveraging the interaction learning of the online and target networks for enforcing representative robustness with only positive samples. Moreover, according to the observation of the potential variations in the target skin images, we select the adaptive augmentation methods to produce the transformed positive views for self-supervised learning. Extensive experiments on two benchmark skin lesion datasets demonstrated that the proposed self-supervised pre-training can stably improve the recognition performance with different numbers of the labeled images compared with the baseline models.","PeriodicalId":338734,"journal":{"name":"2023 18th International Conference on Machine Vision and Applications (MVA)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132750801","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, since there are many moving possibilities, current head pose works, mainly focusing on estimation, fail to provide sufficient temporal information to meet the high demands for accurate predictions. This paper proposes (A) a Spatio-Temporal Encoder (STE), (B) a displacement based offset generating module, and (C) a time step feature aggregation module. The STE extracts spatial information via Transformer and temporal information according to the time order of frames. The displacement based offset generating module utilizes displacement information through a frequency domain process between adjacent frames to generate an offset to refine the prediction result. Furthermore, the time step feature aggregation module integrates time step features based on the information density and hierarchically extracts past motion information as prior knowledge to capture the motion recurrence. Extensive experiments have shown that the proposed network outperforms related methods, achieving a Mean Absolute Error (MAE) of 4.5865° on simple background sequences and 7.1325° on complex background sequences.","PeriodicalId":338734,"journal":{"name":"2023 18th International Conference on Machine Vision and Applications (MVA)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115430653","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
