Image Histogram

Calculates the histogram of an image. An RGB image is expected at the input. If no RGB image is provided, automatic conversion takes place internally.

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

• Bins: Indicates the size of the buffer and thus the number of values that are stored. The number of output channels equals the buffer size.
• Upper Bound: Upper (exclusive) limit of the last histogram bin nBins-1.
• Lower Bound: Lower (including) limit of the 0th histogram bin.

Output values

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