In Range

Block Category: Operations

Input Image Format

Input Image Requirements: None

Description: The In Range block checks each pixel value to see if it is inside the specified RGB ranges and outputs a binary image where white indicates values inside the ranges and black indicates values outside the ranges.

Max Value (R/H/H): Indicates the threshold for the maximum pixel value for red. The value cannot exceed 255.

Max Value (G/S/L): Indicates the threshold for the maximum pixel value for green. The value cannot exceed 255.

Max Value (B/V/S): Indicates the threshold for the maximum pixel value for blue. The value cannot exceed 255.

Min Value (R/H/H): Indicates the threshold for the minimum pixel value for red. The value cannot be lower than 0.

Min Value (G/S/L): Indicates the threshold for the minimum pixel value for green. The value cannot be lower than 0.

Min Value (B/V/S): Indicates the threshold for the minimum pixel value for blue. The value cannot be lower than 0.

Use input connector values to specify the range limits: Adds input connectors to the block to dynamically control the RGB pixel values.

Example

In this example, each pixel is examined to see if its RGB values fall within the specified ranges shown in the Inrange dialog box. Pixel values within the ranges are white.
