Depth map generation based on vanishing lines and vanishing points

摘要

A method can include detecting a pixel direction and a pixel weight for each of a number of pixels in an image, generating one-dimensional (1D) and two-dimensional (2D) histograms based on the pixel directions and weights, and generating a global 2D histogram based on the generated 1D and 2D histograms. The method can also include generating a final depth map based on the global 2D histogram. The method can also include generating a block histogram statistic based on the pixel directions and pixel weights and checking the block histogram based on the block histogram statistic.

1. A method, comprising:
for each of a plurality of pixels in an image, detecting a pixel direction and a pixel weight; generating at least one one-dimensional (1D) histogram and at least one two-dimensional (2D) histogram based on the detected pixel directions and weights; generating a global 2D histogram based on the generated 1D and 2D histograms; and generating a final depth map based on the global 2D histogram.
