Modeling Noise in image sensors

An example that injects noise in images

Types and Sources of Noise

• Spatial
• Temporal

Spatial Noise

• Fixed Pattern Noise
• Does not change frame to frame
•  

Statistical Description

• Gaussian Distribution
• Correlated with Columns
• Row FPN
• Pixel FPN

How is it measured?

• Fit a model to pixels
• How much data to use?
• Specific algorithms to suit a system?

Temporal Noise

• Changes with time
• Column/Row/Pixel
• Frame Temporal Noise

How is it measured?

• Fit Model to data
• Same story as FPN

Test data

• Really easy model
• Generate random pixels
• Add to image based on model

Example Code

• Different options
• Over all flows
• Sample images

How does Rust help?

• Better batteries
• safer
• Better abstraction

What about performance?

• comparison of 30 runs
• Wish list
