Channel subtraction

Description

Creates a new channel by subtracting one channel to another.
Real time: True

Usage

• Pre-processing: Transform the image to help segmentation, the image may not retain it's properties. Changes here will be ignored when extracting features

Parameters

• Channel 1 (channel_1): (default: rd)
• Weight of the first channel (alpha): (default: 100)
• Channel 2 (channel_2): (default: bl)
• Weight of the second channel (beta): (default: 100)
• On result image do (post_processing): Action to perform after subtraction to return an image (default: normalize)
• Threshold min value (min): (default: 0)
• Threshold max value (max): (default: 255)
• Median filter size (odd values only) (median_filter_size): (default: 0)
• Morphology operator (morph_op): (default: none)
• Kernel size (kernel_size): (default: 3)
• Kernel shape (kernel_shape): (default: ellipse)
• Iterations (proc_times): (default: 1)
