Image to apply Gaussian blur

Sigma (Standard Deviation)

Standard deviation for Gaussian distribution. Higher = more blur

Kernel Size (Theory)

Theoretical kernel size for Gaussian calculation. Sharp uses optimized algorithms internally.

Iterations

Number of times to apply Gaussian blur. More iterations = stronger effect

Output Mode

Additional processing on the blurred output
