These methods are automatic and fast, yielding high accuracy and precision, thus reducing the load of manual analysis. However, deep learning usually requires large amounts of diverse, labelled data for training which can be difficult or infeasible to obtain, especially for medical images. For example, privacy concerns and lack of confidentiality agreements are common and are an obstacle to the sharing of useful training data. Additionally, some data can be significantly more difficult to obtain in the first place such as that of rare pathologies. Even in cases where sufficient data is available, the cost and time to perform image labelling can be significant. In many cases, data augmentation is employed to enhance the size of the training set. Similarly, semisupervised learning (SSL) can be used to exploit potentially large amounts of unlabeled data which would otherwise be unused. Motivated by this, in this study, we propose an enhanced StyleGAN2-based data augmentation method for OCT images by employing SSL through a novel crosslocalisation technique. For OCT image patches, the proposed method significantly improved the classification accuracy over the previous GAN data augmentation approach which uses labelled data only. The technique works by automatically learning, mixing, and injecting unlabelled styles into the labelled data to further increase the diversity of the synthetic data. The proposed method can be trained using differing quantities of both labelled and unlabelled data simultaneously. The method is simple, effective, generalizable and can be easily applied and used to extend StyleGAN2. Hence, there is also significant potential for the proposed method to be applied to other domains and imaging modalities for data augmentation purposes where unlabelled data exists.","PeriodicalId":159377,"journal":{"name":"2022 International Conference on Digital Image Computing: Techniques and Applications (DICTA)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128998040","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}

Many previous studies have investigated extreme cases such as dark, rainy and foggy environments and proposed various datasets for these different tasks. In this work, we explore another extreme case: destructive over-exposure which may result in different degrees of content loss due to the limitations of dynamic range. These over-exposure cases can be found in most outdoor datasets with structured or unstructured environments but are usually neglected as they are mixed with other well-exposed images. To analyse the influence imposed by this kind of corruption, we generate realistic over-exposed images based on existing outdoor datasets using a simple but controllable formula proposed in a photographer's view. Our simulation is realistic, indicated by similar illumination distributions to other real over-exposed images. We also conduct several experiments on our over-exposed datasets and discover performance drops using state-of-the-art segmentation models. Subsequently, to address the over-exposure problem, we compare several image restoration approaches for over-exposure recovery and demonstrate their potential effectiveness as a preprocessing step in scene parsing tasks.","PeriodicalId":159377,"journal":{"name":"2022 International Conference on Digital Image Computing: Techniques and Applications (DICTA)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129489080","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}

Despite diligent efforts that have been made to develop deepfake detection techniques, existing approaches often generalize poorly when the characteristics of new data and tasks differ significantly from the ones involved in their initial training phase. The detectors' limited generalizability hinders their widespread adoption if they cannot handle unseen manipulations in an open set. One solution to this issue is to endow the detectors with the capability of lifelong learning from the new data to improve themselves. However, it is not uncommon in real-world scenarios that the amount of training data associated with a certain deepfake algorithm is limited. Therefore, the effectiveness and agility of a continual learning scheme depend heavily on its ability to learn from limited new data. In this work, we propose a deepfake detection approach that combines spectral analysis and continual learning methods to pave the way towards generalized deepfake detection with limited new data. We demonstrate the generalization capability of the proposed approach through experiments using five datasets of deepfakes. The experiment results show that our proposed approach is effective in addressing catastrophic forgetting despite being updated with limited new data, decreasing the average forgetting rate by 35.04% and increasing the average accuracy by 22.45% compared without continual learning.","PeriodicalId":159377,"journal":{"name":"2022 International Conference on Digital Image Computing: Techniques and Applications (DICTA)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115174462","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}

In these situations the segmentation model must be able to handle these variations with predictable and consistent results. Although deep learning can segment point clouds accurately it often suffers with generalisation, adapting poorly to data which is different than the data it was trained on. To address this issue, we propose to utilise multiple available open source fully annotated datasets to train and test models that are better able to generalise. The open-source datasets we utilise are DublinCity, DALES, ISPRS, Swiss3DCities, SensatUrban, SUM, and H3D [5], [11], [10], [1], [3], [2], [6]. In this paper we discuss the combination of these datasets into a simple training set and challenging test set which evaluates multiple aspects of the generalisation task. We show that a naive combination and training produces improved results as expected. We also show that an improved sampling strategy which decreases sampling variations increases the generalisation performance substantially on top of this. Experiments to find the contributing factor of which variables give this performance boost found that none individually boost performance and rather it is the consistency of samples the model is evaluated on which yields this improvement.","PeriodicalId":159377,"journal":{"name":"2022 International Conference on Digital Image Computing: Techniques and Applications (DICTA)","volume":"93 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125226494","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, clinical practice constraints can lead to sub-optimal DWI acquisitions with missing slices (either due to a limited field of view or the acquisition of disrupted slices). To avoid discarding valuable subjects for group-wise studies, we propose a novel 3D Tensor-Wise Brain-Aware Gate network (TW-BAG) for inpainting disrupted DTIs.

The problem occurs when the RFID tag is lost or damaged. A biometric solution identifies the cattle and helps to assign the lost or damaged tag or replace the RFID-based system. Muzzle patterns in cattle are unique biometric solutions like a fingerprint in humans.

As a result of its multi-kernel design, MKIS-Net is a light-weight architecture with a small number of trainable parameters. Moreover, these multi-kernel receptive fields also contribute to better segmentation results. We demonstrate the efficacy of MKIS-Net on several tasks including segmentation of retinal vessels, skin lesion segmentation, and chest X-ray segmentation. The performance of the proposed network is quite competitive, and often superior, in comparison to state-of-the-art methods.

First, we merge point clouds of two 3D models in certain ways described by a prompt. The prompt acts like the annotation describing each 3D scene. Later, we perform contrastive learning to train our proposed architecture in an end-to-end manner. We argue that 3D scenes can relate objects more efficiently than single objects because popular language models (like BERT) can achieve high performance when objects appear in a context. Our proposed prompt-guided scene generation method encapsulates data augmentation and prompt-based annotation/captioning to improve 3D ZSL performance.

When the number of training samples is small, or the class labels are noisy, networks tend to memorize patterns specific to individual instances to minimize the training error. This leads to the issue of overfitting and poor generalisation performance. This paper explores a remedy by suppressing the network's tendency to rely on instance-specific patterns for empirical error minimisation. The proposed method is based on an adversarial training framework. It suppresses features that can be utilized to identify individual instances among samples within each class. This leads to classifiers only using features that are both discriminative across classes and common within each class. We call our method Adversarial Suppression of Identity Features (ASIF), and demonstrate the usefulness of this technique in boosting generalisation accuracy when faced with small datasets or noisy labels.
