Depth Processing nodes generate and change depth data using various techniques.

Generates a greyscale luminance image from a depth source, usually a Depth Camera / Kinect Source

Feature tracking nodes detect and track features in an image.

Blob Tracker	This node generate blobs from an input image, and outputs transformation information for each of those blobs.
Face Tracker	Searches the supplied image or video for faces.
NVIDIA AR Body Tracker	Utilise the NVIDIA Broadcast SDK on RTX GPUs to generate rigged skeleton poses based on 2D video.

These nodes analyse and modify the image with different effects.

Composite Sources	Composite two image sources to one image.
Downsample	Downsample the resolution of the input image.
Frame Buffer	Buffers a frame for a period of time.
Frame Delay Frame	Delays the image played by a specified frame amount.
Generate Normal Map	Generates a normal map based off the luminance values from an image.
Resize	Resizes an image to specified size.
Upsample	Upscale the resolution of the image.

These nodes control where video is imported from, and where video is output to.

Colour And Depth Source	Combines two input images and generates a depth camera source from them.
Depth Camera Source	Read colour and depth data from a Kinect camera.
Dynamic Image Loader	Loads an image from disk based on a specified filename.
GBuffer To Image	Allows GBuffer channels from a rendered scene to be used as video nodes for compositing or export purposes.
Image Tile File Loader	Loads a series of images from disk and composes them as tiles inside a single large texture.
Multiplex Sources	Takes multiple video inputs and outputs a single video based on the Source Index attribute.
Rendered Video Source	Output the rendered image from a Render Layer node for other nodes to use.
Video Clip	An alternative source for an imported video or image source from the resources window.
Video NDI Source	Use input from an NDI IP video stream.

TODO Section Description

Optical Flow	Analyses an image and visualise the movement of objects in the scene.
Temporal Filter	Combines multiple frames together and filters out overlapping values.

Segmentation	TODO Section Description
Loader	Source for a video or image from a file or from a media server (when running as a block).
Video In	Use input from a video capture device (DirectShow / Media Foundation).
Video Null	Creates a copy of the upstream video node.
