Extracts the color features of the image.
Use this node for color matching or other applications that require with color information, such as color identification and color image segmentation.
Reference to the color image from which to learn color information.
Regions in the image that contain the colors to learn.
If ROI descriptor contains multiple regions, the node accumulates color information in each region before learning. If ROI descriptor is empty or not connected, the node considers the entire image as a single region.
Coordinates of the bounding rectangle.
Individual shapes that define an ROI.
Object specifying if contour is the external or internal edge of an ROI.
Shape type of the contour.
Relative position of the contour.
Sensitivity of the color information in the image.
Set to High Sensitivity to distinguish colors with close hue values.
Default: Low
Threshold value to distinguish two colors with the same hue value.
Default: 80
Error conditions that occur before this node runs.
The node responds to this input according to standard error behavior.
Standard Error Behavior
Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.
Default: No error
Reference to the source image.
Color features found in the image region.
These features represent the color information in the image region in a compact form.
Error information.
The node produces this output according to standard error behavior.
