Stereo images are fundamental to numerous applications, including extended
reality (XR) devices, autonomous driving, and robotics. Unfortunately,
acquiring high-quality stereo images remains challenging due to the precise
calibration requirements of dual-camera setups and the complexity of obtaining
accurate, dense disparity maps. Existing stereo image generation methods
typically focus on either visual quality for viewing or geometric accuracy for
matching, but not both. We introduce GenStereo, a diffusion-based approach, to
bridge this gap. The method includes two primary innovations (1) conditioning
the diffusion process on a disparity-aware coordinate embedding and a warped
input image, allowing for more precise stereo alignment than previous methods,
and (2) an adaptive fusion mechanism that intelligently combines the
diffusion-generated image with a warped image, improving both realism and
disparity consistency. Through extensive training on 11 diverse stereo
datasets, GenStereo demonstrates strong generalization ability. GenStereo
achieves state-of-the-art performance in both stereo image generation and
unsupervised stereo matching tasks. Our framework eliminates the need for
complex hardware setups while enabling high-quality stereo image generation,
making it valuable for both real-world applications and unsupervised learning
scenarios. Project page is available at https://qjizhi.github.io/genstereo
