WebDepth from defocus (DfD) is one of the popular passive depth sensing approaches in computer vision. Usually, it utilizes the defocus blur depth cue encoded in images, captured by a single... WebAbstract. We present a method that takes as input a single dual-pixel image, and simultaneously estimates the image’s defocus map—the amount of defocus blur at each pixel—and recovers an all-in-focus image. Our method is inspired from recent works that leverage the dual-pixel sensors available in many consumer cameras to assist with ... handheld instruments musicalWebThe auxiliary cameras are well calibrated and act as a passive depth sensor by generating disparity maps.
