A method and a system for generating depth information associated with an image. The system comprises a segmentation module arranged to identify a plurality of objects represented by the image, wherein each object adjacent to another object are identified by an edge arranged to substantially separate the object and the adjacent object; and a processing module arranged to generate the depth information by assigning a depth value for each of the plurality of objects, wherein the depth value is arranged to represent a distance between the object and a reference point in a three-dimensional space.
