=======================
DETAILS OF THE DATABASE
=======================

This database consists of 12 sets of color images and dense ground-truth range maps.
Both the color images and range maps have high-definition resolution of 1280x720.
The color images are in PNG (Portable Network Graphics) format, and the range maps are in MAT (MATLAB binary file for storing variables) format.
Each range map file contains a 'scene_range' variable, which is a two-dimensional matrix.
In 'scene_range', each element represents the range value in the unit of meter (m) of its corresponding pixel in the color image.
Note that any range value equal to zero means that there is no valid 3D point cloud returned from the range scanner, resulting in no valid range value at the corresponding 2D pixel location.
