Method and system for enhancing layering of depth map

Abstract

The invention relates to a method and system for enhancing the layering of a depth map. The method comprises: dividing the depth value range in the depth map into N depth value zones with the same size; generating a first distribution histogram of the depth map in the N depth value zones with the same size; redividing the depth value range into N depth value zones with different size according to the speed at which the depth value distribution changes in the first distribution histogram; generating a second distribution histogram of the depth map in the redivided N depth value zones with the different size; and generating a new depth map according to the second distribution histogram. By adopting the method and system, the new depth map with higher layering effects and higher distinguishing capabilities can be generated according to the distribution characteristics of the original depth map.

Description

technical field [0001] The invention relates to a method and system for enhancing the sense of layering of a depth map. Background technique [0002] The distance of each point in the scene relative to the camera can be represented by a depth map (Depth Map), that is, the pixel value of each pixel in the depth map represents the distance between a certain point in the scene and the camera. Depth information can be estimated indirectly by using light and shade features, texture features, and motion features of grayscale images. [0003] In the prior art, the stereoscopic image synthesis process usually first generates the corresponding depth map from the acquired image, and then synthesizes the stereoscopic image according to the depth map, but the depth map generated by this method generally has low resolution, that is, a sense of hierarchy. Correspondingly, the stereoscopic images synthesized based on these depth maps will also have insufficient stereoscopic perception. Th...

[0003] In the prior art, the stereoscopic image synthesis process usually first generates the corresponding depth map from the acquired image, and then synthesizes the stereoscopic image according to the depth map, but the depth map generated by this method generally has low resolution, that is, a sense of hierarchy. Correspondingly, the stereoscopic images synthesized based on these depth maps will also have insufficient stereoscopic perception. Therefore, there is an urgent need for a method and system for enhancing the layering of the depth map to generate a stronger layering. A more resolving depth map
