Procedure of Using Color Checker Node
Link input image.
2. Define search region. 1. Define Color. 2.
Define Region
In color segmentation, node will consider all defined region as a single combined region. In color matching, node will match each defined region to the nearest color sample.
There is 3 way for defining a region:
- Use Image Mask.
Input a Image Mask that has same size as Color Image. Node will define only one single region base on the mask.
- Define from mod finder node
Input a Mod Finder Result comes from mod_finder node Select one model in Mod Finder Result. One region will be defined for each object found from mod_finder. Draw mask on model to define the color match region related to object
- Define from display
Draw a rectangle box from main display Draw mask for this region
Color Sample
The node will only match regions to defined color
There are 2 ways to define a color sample
- Define color by area.
Draw a box on display, node will calculate the average color of this box, and save it as color sample value. Additionally, you can draw/erase mask to change pixels included when calculate average.
- Define color by value
Define a RGB value as color sample. The color can be set from a color board, manually set HSV or RGB value, or pick a pixel’s color from the screen.
