Nonlinear Filters

Nonlinear filters modify the value of each pixel in an image based on the value returned by a nonlinear function calculation that analyzes the neighboring pixels. Nonlinear filters are mostly used for noise removal and edge detection.

Black Ice imaging tools currently support the following nonlinear filters:

• Alpha-Trimmed Mean Filter

• Contra-Harmonic Mean Filter

• Geometric Mean Filter

• Harmonic Mean Filter

• Maximum Filter

• Median Filter

• Midpoint Filter

• Minimum Filter

• Range Filter

• Weighted Median Filter

• Yp Mean Filter
