Diffusion Model-Based Data Synthesis Aided Federated Semi-Supervised Learning
[ "cs.LG", "cs.AI", "cs.IT", "math.IT" ]
Federated semi-supervised learning (FSSL) is primarily challenged by two factors: the scarcity of labeled data across clients and the non-independent and identically distribution (non-IID) nature of data among clients. In this paper, we propose a novel approach, diffusion model-based data synthesis aided FSSL (DDSA-FSS...

Depth Any Camera: Zero-Shot Metric Depth Estimation from Any Camera
[ "cs.CV", "cs.AI", "cs.RO" ]
While recent depth estimation methods exhibit strong zero-shot generalization, achieving accurate metric depth across diverse camera types-particularly those with large fields of view (FoV) such as fisheye and 360-degree cameras-remains a significant challenge. This paper presents Depth Any Camera (DAC), a powerful zer...

EOG Communication Interface for Quadriplegics: Prototype & Signal Processing
[ "eess.SP", "cs.SY", "eess.SY" ]
Electrooculography (EOG) is an electrophysiological signal that determines the human eye orientation and is therefore widely used in Human Tracking Interfaces (HCI). The purpose of this project is to develop a communication method for quadriplegic patients using EOG signals aimed at text and voice generation. The syste...

DeTrack: In-model Latent Denoising Learning for Visual Object Tracking
[ "cs.CV" ]
Previous visual object tracking methods employ image-feature regression models or coordinate autoregression models for bounding box prediction. Image-feature regression methods heavily depend on matching results and do not utilize positional prior, while the autoregressive approach can only be trained using bounding bo...
