Abstract:
There are provided a method and an apparatus for generating a depth map of a stereoscopic image that are capable of representing the depth perception of an image more finely by considering not only vanishing points but also fine lines formed within an image. The method includes: generating multiple line segments by grouping multiple edge pixels within an input image based on an intensity gradient direction; merging the multiple line segments based on similarity and thereafter detecting at least one vanishing point in consideration of a result of the merging; and generating an energy depth function on which correlation between the line segments and the vanishing point is reflected and generating a depth map by decoding the energy depth function.
