To date, research on relation mining has typically focused on analyzing explicit relationships between entities, while ignoring the underlying connections between entities, known as implicit relationships. Exploring implicit relationships can reveal more about social dynamics and potential relationships in heterogeneous social networks to better explain complex social behaviors. The research presented in this paper explores implicit relationships discovery methods in the context of heterogeneous social networks.

Deepfakes represent one of the toughest challenges in the world of Cybersecurity and Digital Forensics, especially considering the high-quality results obtained with recent generative AI-based solutions. Almost all generative models leave unique traces in synthetic data that, if analyzed and identified in detail, can be exploited to improve the generalization limitations of existing deepfake detectors.

Supplementary material for RID-TWIN: AN END-TO-END PIPELINE FOR AUTOMATIC FACE DE-IDENTIFICATION IN VIDEOS

This document contains supplementary material which outlines key aspects regarding the dataset creation process, along with the methodology employed for benchmarking state-of-the-art deep leaning models. We aim to provide a clear and comprehensive overview, thus dividing the topic into six fundamental points. Beginning with point one, we delve into the method of data collection and organization, elucidating how the data can be interpreted and utilized. This section is crucial for understanding the origin and nature of the data comprising our dataset.

Accurate 3D lane detection from monocular images is crucial for autonomous driving. Recent advances leverage either front-view (FV) or bird’s-eye-view (BEV) features for prediction, inevitably limiting their ability to perceive driving environments precisely and resulting in suboptimal performance. To overcome the limitations of using features from a single view, we design a novel dual-view cross-attention mechanism, which leverages features from FV and BEV simultaneously. Based on this mechanism, we propose 3DLaneFormer, a powerful framework for 3D lane detection.

Multi-class multi-instance segmentation is the task of identifying masks for multiple object classes and multiple instances of the same class within an image. The Segment Anything Model (SAM) is a new foundation model designed for promptable multi-class multi-instance segmentation. SAM is able to segment objects in any image using a pre-defined point grid as an input prompt in the ``everything'' mode. However, out of the box SAM tends to output part or sub-part segmentation masks (under-segmentation) in different real-world applications.

In this work, we present SynTable, a Python-based dataset generator built using NVIDIA's Isaac Sim Replicator Composer for generating high-quality synthetic datasets for unseen object amodal instance segmentation of cluttered tabletop scenes. Our tool renders complex 3D scenes containing object meshes, materials, textures, lighting, and backgrounds. Metadata, including modal and amodal instance segmentation masks, occlusion masks, depth maps, and bounding boxes can be automatically generated based on user requirements.

We address distinguishing whether an input is a facial image by learning only a facial-expression recognition (FER) dataset.
