Image Tile Extractor

Tools > Image Tile Extractor

Splits images into a specified number tiles or extracts features from image tiles using a processing recipe. Can accept a mixture of images and folders of images.

Two extraction modes are available:

• Grid Mode: Basic tile extraction that splits images into uniform tiles. Especially useful for sub-sectioning images prior to applying a Spotlight based recipe with higher resolution to automate feature tracing for Deep Learning model training.
• Features Mode: Applies a processing recipe to extract tiles around identified features. Enables certain measurement workflows that require one feature per image.
  

1. Images and Folders

List of images and folders to process for tile extraction. Count will reflect number of individual images plus number of images in the root of all selected folders. Folder entries in the list are denoted by a folder icon. Drag and drop images and folders into this box to add.

2. Add

Browse the file explorer to add images and folders.

3. Remove

Remove images and folders from the list.

4. Clear

Remove all images and folders from the list.

5. Output Location

Folder where tiles should be output. Set by default to the parent directory of the first image or folder added to the list. Can be changed either by browsing the file explorer of manually typing a valid folder path. If “Create subfolder” is checked, an “image_tiles” folder is created in the specified output location.

6. Mode Selection

Toggle between Grid and Features extraction modes. See above for mode descriptions.

7. Tiles (Grid Mode)

Number of tiles to split each image into in X by Y format.

8. Load Recipe (Features Mode)

Select a processing recipe file (.rcp) to apply to each extracted tile. Only visible when Features mode is selected. The recipe will be executed on each image to identify features. The bounding box around each feature will be extracted from the original image.

9. Padding/Buffer (Features Mode)

Specify pixel padding around each tile to provide context for edge features. This buffer extends the bounding box of the identified features to ensure features are not against the edges of their respective tiles after extraction

10. Extract

Perform the tile extraction. In Grid mode, creates simple image tiles. In Features mode, applies the selected recipe to each image and outputs tiles around identified features. A status message will appear to the right after extraction to confirm the number of extracted tiles and processing status.
