METHOD OF AND ARRANGEMENT FOR BLURRING AN IMAGE
First Claim
1. Method of reducing the spatial resolution of images comprising:
- acquiring an input image comprising image parts having a spatial resolution larger than SR pixels/meter;
acquiring a depth map associated with said input image;
determining for each pixel p(x,y) a spatial resolution value by means of the depth map;
processing a region of pixels of said input image for which holds that the spatial resolution value is larger than a predefined threshold corresponding to SR pixels/meter to obtain a corresponding region of pixels having a spatial resolution smaller then or equal to SR pixels/meter in an output image.

Abstract
A method of reducing the spatial resolution of images is disclosed. At least one embodiment of the method includes: —acquiring an input image including image parts having a spatial resolution larger than SR pixels/meter; —acquiring a depth map associated with the input image; —determining for each pixel p(x,y) a spatial resolution value by means of the depth map; —processing a region of pixels of the input image for which holds that the spatial resolution value is larger than a predefined threshold corresponding to SR pixels/meter to obtain a corresponding region of pixels having a spatial resolution smaller then or equal to SR pixels/meter in an output image. The method enables to removes privacy information from images by reducing the spatial resolution to a level that the privacy information cannot be recognized in the image anymore.
