Abstract:
1. A method for determining a depth estimate for at least one pixel in a reference image, the reference image being one of a plurality of images of a three dimensional scene, the method including: a) providing access to a depth analysis engine comprising a device interface; b) obtaining, by the depth analysis engine, a plurality of images including a reference image representative of a scene via the device interface, wherein each of the plurality of images comprises a different perspective of the scene; c) determining first depth estimates for first pixels in a first resolution of the reference image using a parallax method, the first resolution being a lowest resolution; d) determining, by the depth analysis engine, current depth estimates for current pixels in a current resolution of the reference image by using previous depth estimates for equivalent previous pixels in a previous resolution of the reference image, the previous resolution being lower than the current resolution; and e) deriving, by the depth analysis engine, a refined depth estimate by refining the current depth estimate for at least one current pixel via: f) configuring a device to initiate an action as a function of the refined current depth estimate.
