Remarks

For Beginners: Color jitter randomly adjusts brightness, contrast, and saturation of video frames. This helps models become robust to different lighting conditions and camera settings.

When to use:

• Videos captured with different cameras or lighting
• Outdoor videos with varying light conditions
• Reducing overfitting to specific color characteristics

Constructors

VideoColorJitter(double, double, double, double, double)

Creates a new video color jitter augmentation.

public VideoColorJitter(double brightnessRange = 0.2, double contrastRange = 0.2, double saturationRange = 0.2, double probability = 0.5, double frameRate = 30)

Parameters

brightnessRange double

Brightness adjustment range (default: 0.2).

contrastRange double

Contrast adjustment range (default: 0.2).

saturationRange double

Saturation adjustment range (default: 0.2).

probability double
