Title: Creating a depth map

Abstract: A method of generating a depth map (122) comprising depth values representing distances to a viewer, for respective pixels of an image (100), is disclosed. The method comprises: determining a contour (106) on basis of pixel values of the image (100), the contour comprising a collection of adjacent points; computing curvature vectors (108 114) at a number of the points; and assigning a first one of the depth values corresponding to the first one of the pixels on basis of the curvature vectors (108-114).
