New imaging research: posttractable and selective zooming

New imaging research: posttractable and selective zooming

[11:30 thu,10.August 2017   by ]    



Interesting but more relevant to the photo area is a new method presented in the framework of the Siggraph, in order to subsequently modify the focal length effect in an image by means of algorithms. Multi-perspective views, which can not be achieved on a natural optical path, should also be possible. In the calculations, a depth map is compiled roughly, ie the position of the image parts relative to one another in the depth of the space is determined, whereupon the front and background elements can be scaled relative and independently. Thus, the depth impression of the represented space changes as with the use of different lens focal lengths - the background with a wide-angled recording into the distance and works smaller, it is zoomed in and zoomed in at telephoto. thisThe researchers at the University of California, together with Nvidia developers, want to simulate this method. Pic1 For this "computational zoom", a series of photos must be taken from a subject at the same focal length, but increasing or decreasing distance between camera and subject to feed the algorithms with enough different (size) views. The spatial geometry is then estimated or best reconstructed. As a result, the image parts can be re-arranged as can be seen in the video - for example, a human being can be distorted in the foreground, parts of the image moved laterally from the middle and a building in the background can be fetched, reflecting the effect of different focal lengths in the same shot correspond.
