Image Processing in VR and AR

What Is Image Processing?

Image processing involves manipulating, analyzing, and interpreting images using algorithms. It transforms raw visual data into useful information.

Common Image Processing Operations

• Image enhancement – improving clarity, contrast, and detail.
• Filtering – reducing noise or sharpening edges.
• Segmentation – dividing an image into regions or objects.
• Feature extraction – identifying edges, corners, shapes, or patterns.
• Object detection & recognition – finding and labeling objects in an image.
• Motion analysis – tracking movement across frames.

 

Image Processing in Augmented Reality (AR)

Augmented Reality overlays digital content onto the real world. To do this convincingly, AR must continuously analyze its surroundings and image processing makes it possible.

·         Detects surfaces like floors and tables
AR systems analyze camera frames to identify flat surfaces where virtual objects can be placed. This is done using feature detection and depth estimation.

 

·         Anchors virtual objects realistically in physical space
AR uses depth data and lighting estimation to ensure virtual objects stay fixed in place and look natural as the user moves around.

 

Image Processing in Virtual Reality (VR)

Virtual Reality creates a fully simulated environment. While VR does not overlay onto the real world, it still relies on image processing to ensure realistic immersion and user movement.

·         Tracks head, hand, and body movement in real time
Cameras and sensors capture user movement. Image processing extracts motion data, ensuring the virtual world responds instantly to direction changes.

·         Produces stereoscopic (3D) views for immersive visuals
VR systems render two images—one for each eye. Image processing aligns them to create a realistic sense of depth.
