Decoupling While Coupling: Towards More Accurate Stereo Image Sand Removal Beyond Certainty

ICASSP 2025accepted

Stereo image sand removal is crucial to improve the perceptual quality for autonomous driving perception. Existing methods often fall short in accurately estimating the uncertainty inherent in degraded images, leading to suboptimal outcomes. To address this, we introduce a novel framework named Deco…

A Transformer-Based Object Detector with Coarse-Fine Crossing Representations

NeurIPS 2022accept

Transformer-based object detectors have shown competitive performance recently. Compared with convolutional neural networks limited by the relatively small receptive fields, the advantage of transformer for visual tasks is the capacity to perceive long-range dependencies among all image patches, wh…

An Efficient Framework for Detection and Recognition of Numerical Traffic Signs

ICASSP 2022accepted

Due to the variety of categories and uneven distribution of available samples, automatic traffic sign detection and recognition is still a challenging task. For those categories with less training data, existing deep learning methods cannot achieve desirable performance, and the overall detection ef…
