Extract Region by RGB Values

Extract specific semantic regions from segmentation output by specifying RGB color values. Define RGB values (e.g., RGB 135,206,235 for sky), and the tool isolates regions matching those colors. Perfect for color-based region extraction, batch processing with known color ranges, and programmatic workflows.

What it does

Color Pick by RGB works with segmentation model outputs to extract specific semantic regions by matching RGB color values. You specify the RGB color(s) to match (e.g., RGB 135,206,235 for sky blue), and the tool isolates regions from the segmentation that match those colors—either as a mask, cropped image, or isolated overlay. Essential for color-based region extraction and segmentation validation workflows.

Problem it solves

• Color-based extraction – Extract regions by specifying RGB values
• Known color ranges – Extract when you know the color of target region
• Segmentation validation – Verify segmentation by checking colored regions
• Region matching – Find all pixels matching specific RGB colors
• Color-to-class mapping – Verify segmentation class colors
• Quick extraction – Fast color-based region selection

Input/Output

<aside>

• Input: Segmentation output + RGB color value(s)
  • Segmentation: Output from segmentation model (with color-coded regions)
  • RGB input: Specify target RGB values (e.g., (255 0 0), 255 0 0, or (255, 0, 0))

• Output: Extracted region - Binary mask showing only selected class (white = selected, black = rest) </aside>

How to Use with Segmentation

1. Load segmentation → Get output from segmentation model (DeepLabV3, SegFormer, etc.)

   

2. Set RGB values → Enter or pick target RGB color (e.g., (255 0 0), 255 0 0, or (255, 0, 0))

   

3. Generate output → Tool extracts selected class region

   

   You can keep the segmented color if you check ‘keep_color for conditional’

   

Note: Color Pick by RGB requires a color-coded segmentation model output. It extracts/isolates specific regions by matching RGB color values. Perfect for color-based region extraction, segmentation validation, batch processing, and automated workflows.
