Abstract
Systems and methods for performing multimedia conversion are disclosed. In a multimedia conversion system for converting two-dimensional (2D) multimedia data to stereoscopic multimedia data, an absolute difference between pixel pairs is determined for each scan line in a frame of the 2D multimedia data. The absolute difference values are accumulated, and a depth map is derived based on the accumulated difference values. The depth map is applied to the frame in the 2D multimedia data.
