According to examples, a head-mounted display (HMD) headset may include at least two exterior-facing color cameras mounted on the front face of the HMD and in the same visual plane as the user's eyes. The at least two exterior-facing color cameras may collect images for stereo view synthesis. The HMD may include a processor, and a memory storing instructions, which when executed by the processor, cause the processor to perform stereo view synthesis with a machine-learning (ML) based technique including at least one of depth estimation, imaging sharpening, forward splatting, disocclusion filtering, or fusion.
