All-directional Disparity Estimation for Real-world QPD Images

CVPR 2025highlight

Quad Photodiode (QPD) sensors represent an evolution by providing four sub-views, whereas dual-pixel (DP) sensors are limited to two sub-views. In addition to enhancing auto-focus performance, QPD sensors also enable disparity estimation in horizontal and vertical directions. However, the characteri…

FasterGold-DETR: An Efficient End-to-End Fire Detection Model via Gather-and-Distribute Mechanism

ICASSP 2025accepted

Fire detection technology based on deep learning methods has become a prevalent practice. However, the performance of current YOLO-based detection models is limited by NMS, and DETR-based detection models struggle with real-time performance. To address these challenges, a new fire detection model, F…

Quad-Pixel Image Defocus Deblurring: A New Benchmark and Model

CVPR 2025poster

Defocus deblurring is a challenging task due to the spatially varying blur. Recent works have shown impressive results in data-driven approaches using dual-pixel (DP) sensors. Quad-pixel (QP) sensors represent an advanced evolution of DP sensors, providing four distinct sub-aperture views in contras…
