摘要：
In the image processing method, a first two-dimensional image (I(x, y)) of a three-dimensional scene is obtained. Each pixel location of the first image is associated with a respective distance parameter (z(x, y)) representing a distance of a viewer's eye to an object of the scene appearing at this pixel location in the first image. A respective spreading parameter (¦ d (x, y)) is determined for each pixel location as a function of the distance parameter associated with this pixel location. A second, blurred two-dimensional image (I'(x, y)) is generated from the first image using a local convolution kernel varying across the image. This kernel is sparse since it has a number of non-zero points much smaller than the number of points of a blur region whose dimension is given by the spreading parameter.
