This is a neat idea.<br /><br />My big concern is the reconstruction of high frequencies. Traditional demosaickers assume identical high frequencies for all color planes. Clearly this cannot work for depth sensing, and Dual Aperture needs to reconstruct IR, RGB planes independently. Furthermore, this has be done with very low aliasing. Aliases of different colors have different phases and will result in large cyclic fluctuations of depth estimate.<br /><br />The image reconstruction problem is formidable, especially since the plain RGBW demosaicking problem has not beensatisfactorily solved so far. It will be interesting to see how they solve these problems and how much resolution hit they take.Tripurari Singhhttp://www.imagealgorithmics.comnoreply@blogger.com
