#parallaxis

Parallaxis is a simple viewer for images captured by depth cameras like the Microsoft Kinect and the Intel Realsense series. Depth images are normalized to make them easier to inspect visually and can optionally be displayed using a colormap. It is also possible to normalize all images to the same range so that there is no flickering when scrolling through them. Parallaxis requires a C++17 compliant compiler and OpenCV 3/4.

#Usage

parallaxis can show one or more images, all images in one or more directories or a combination of images and directories. If no arguments are provided then any images in the current working directory will be shown.

parallaxis depth1.png depth2.pgm  # multiple images
parallaxis dir/                   # images in directory
parallaxis                        # images in current directory
parallaxis -N dir/ depth/         # common normalization for images in 2 directories

Only grayscale images are normalized and shown using a colormap. RGB images are shown unchanged.

Run man parallaxis or parallaxis --help for more info about the program.
