Calculates the local variance of an image.

Optionally, a Boolean signal can be selected for the Enable Execution input so that the algorithm is only active if the value of the selected signal is TRUE.

Configuration options

• Kernel Size: Size of the filter kernel.
• Scale: Scaling factor for the calculated variance values.
• Border Type: Treatment of the image border.

Output values

• Count Results: Is incremented when a new result is provided.
• hr: HRESULT error code that outputs the result of the processing.
• Image: Initial image of the algorithm.
• New Result: (Optional) TRUE if a new result is provided.
