All-directional Disparity Estimation for Real-world QPD Images

Hongtao Yu, Shaohui Song, Lihu Sun, Wenkai Su, Xiaodong Yang, Chengming Liu

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…

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

Hang Chen, Yin Xie, Xiaoxiu Peng, Lihu Sun, Wenkai Su, Xiaodong Yang +1

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…
