Abstract

In example embodiments, methods, apparatus and computer program products are provided. The method includes facilitating receiving a first image and a second image. A first total cost amount and a second total cost amount associated with pixels of the first image and the second image are determined for a plurality of disparity values. A first disparity map and a second disparity map are generated based on the first total cost quantity and the second total cost quantity. Based on the first total cost amount, a confidence map is generated for the disparity values ​​of the first image. One or more infinite regions in the first image are determined based on the number of confident pixels in the color segmentation of the first image. By determining filtered disparity values ​​for pixels of the first image, a third disparity map is generated, wherein the filtered disparity values ​​for pixels of the one or more infinite regions are predefined disparity values.

Description

technical field [0001] Various embodiments generally relate to methods, apparatus and computer program products for disparity map estimation of stereoscopic images. Background technique [0002] Various electronic devices, such as cameras, mobile phones, and other multimedia devices are widely used to capture images of scenes. Some electronic devices are capable of capturing stereoscopic images and using the stereoscopic images for disparity map estimation of the scene. Disparity map estimation is the process of determining the displacement in pixels between stereo images. Typically, disparity maps contain erroneous disparities around object outlines and missing disparities represented as holes or textureless regions. Generally, the completion and filling of the disparity in the disparity map is performed using various methods, such as a Minimum Spanning Tree (MST) based aggregation framework, a horizontal / vertical based aggregation framework, or the like. However, refini...
