Computes the histogram of the image pixel values.
Name | Type | Range | Description | |
---|---|---|---|---|
inImage | Image | Input image | ||
inRoi | Region* | Range of pixels to be processed | ||
inChannelIndex | Integer | 0 - 3 | Selects a channel of the input image | |
inBinSize | Real | 0.0 - | Width of a single histogram bin | |
inDomainBegin | Real | The lowest value that will be considered in the output histogram | ||

Description
Histogram in Adaptive Vision Studio is a graphical representation of data contained in image. That is, the resulting histogram contains number of pixel values from specified channel with selected inBinSize (interval).

This filter can throw an exception to report error. Read how to deal with errors in Error Handling.
List of possible exceptions:
Error type | Description |
---|---|
DomainError | Region exceeds an input image in ImageHistogram. |
DomainError | Selected bin size equals zero in ImageHistogram. |
DomainError | Selected channel index is out of range in ImageHistogram. |
DomainError | Selected domain has zero or negative size ImageHistogram. |
Complexity Level
