Extract Specific Segmented Regions

Extract a specific semantic region from segmentation output by selecting its class. Select a class (e.g., "sky", "person", "car"), and the tool isolates only that region, masking or cropping the rest. Perfect for targeted processing of specific semantic elements in images

What it does

Color Pick by Class works with segmentation model outputs to extract specific semantic regions by their assigned class labels. You select a target class from the available segmentation classes, and the tool isolates that region—either as a mask (isolated region with transparency) or as a cropped image. Essential for semantic-aware image processing and targeted region extraction.

Problem it solves

• Extract semantic regions – Isolate specific objects by class (sky, person, car, etc.)
• Targeted processing – Apply operations to only specific semantic regions
• Region isolation – Focus on objects of interest, hide everything else
• Class-based filtering – Work with only selected semantic categories
• Semantic cropping – Crop to include only specific classes
• Multi-region workflows – Extract different regions for different processing
• Focused analysis – Analyze only relevant semantic regions
• Creative region selection – Artistic/creative selection by semantic meaning

Input/Output

<aside>

• Input: Segmentation output + Class selection
  • Segmentation: Output from segmentation model (DeepLabV3, SegFormer, MaskFormer, etc.)
  • Class selection: Select target class from available segmentation classes
  • Segmentation classes: Model-dependent
  • Format: Any segmentation model output with class labels </aside>

<aside>

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

How to Use

<aside>

0207 (2).mp4

1. Load segmentation → Get output from segmentation model (DeepLabV3, SegFormer, etc.)
2. Select class → Choose target class from available classes (e.g., "sky")
3. Generate output → Tool extracts selected class region
4. You can keep the segmented color if you check ‘keep_color for conditional’ </aside>

Note: Color Pick by Class requires a segmentation model output with class labels. It extracts/isolates specific semantic regions by class. Perfect for semantic-aware image processing, targeted region extraction, and creative compositing workflows.
