Depth Map Adjustment for the Improvement of Stereoscopic Image Perception

Recently, a variety of stereoscopic contents have been provided to academic and industrial fields for broadcasting, movies and mobile materials. However, few works have been interested in the adjustment of 3D contents for diverse displays. For instance, movie contents suited to large screen frequently do not deliver the same 3D perception to small-size screen such as mobile phone, tabular PCs, etc. For this, this paper presents an adjustment method of stereoscopic contents. 2D+Depth is one of popular methods with which stereoscopic images are generated. For this, depth planes are derived based on a depth histogram. By adjusting depth planes, a new depth map is made. Then 2D+Depth produces a stereoscopic image. Experiments performed on various 2D+Depth images validate that the proposed methods deliver more enhanced 3D depth based on subjective evaluation experiments.
