Create Image Sample Library

Feature Description

An image sample library is the core container for organizing and managing sample images, vector labels, and classification systems. By creating a sample library, you can specify the annotation type (single-temporal or bi-temporal), add images, and configure corresponding vector label datasets, laying the foundation for subsequent sample annotation and deep learning model training. After the sample library is created, the Manage Image Sample view will be activated for centralized annotation operations.

Functional Entry

Start Tab -> Browse Group -> Sample Drop-down Menu -> New Image Sample Library.

Operation Instructions

  1. Click the Start Tab -> Browse Group -> Sample Drop-down Menu -> New Image Sample Library button. The Create a New Image Sample Library dialog box will pop up.
  2. Set the image sample library name, which defaults to SampleImage. If a sample library with the same name already exists in the system, the default name suffix will automatically be appended with "_n" for differentiation (e.g., SampleImage_1, SampleImage_2).
  3. Select the dimension type:
    • Single-temporal Image: For annotating a single image, providing only one annotation window.
    • Bi-temporal Image: Provides a pre-event image window and a post-event image window. Supports synchronously annotating the image from the other time phase while annotating either the pre-event or post-event image, suitable for change detection scenarios.
  4. Add sample images based on the selected annotation type.
    • Single-temporal Image: Supports adding files, folders, lists, and datasets. Adding datasets includes mosaic datasets, read-only image data opened in the current workspace, and imported image data.
    • Bi-temporal Image: The list is divided into two columns: Pre-event Image and Post-event Image. Creation can only be confirmed after specifying a corresponding post-event image for each pre-event image.
      • Add List: Requires selecting the pre-event image manifest file and the post-event image manifest file separately. The system will automatically match pre-event and post-event image pairs by line number. The pre-event image list is mandatory; the post-event image can be specified manually.
      • Other Addition Methods: By default, pre-event images are added. Users need to manually specify the corresponding post-event image for each pre-event image in the list.
  5. Set Sample Tags: Configure the vector dataset used to store annotation results. Use the toolbar buttons (Add, Select All, Invert Selection, Delete) to manage the list. The column headers in the sample tag list are described as follows:
    • Datasource: Defaults to the data source selected in the current Workspace Manager.
      • If none is selected, the first data source in the Workspace Manager is used.
      • If there are no opened readable/writable data sources in the Workspace Manager, this defaults to empty.
      • The drop-down list includes all readable/writable data sources and supports opening and creating new data sources.
    • Dataset: Defaults to the first region dataset of the selected data source. If none exists, it is empty. The drop-down list provides all region datasets for that data source and supports creating new ones.
    • Label Field: Configure the field for storing label object property information.
      • Single-temporal Image: Creates a text field named LabelType by default. The drop-down menu supports selecting existing text fields or creating a new field.
      • Bi-temporal Image: Set the Pre-event Label Field and Post-event Label Field separately, corresponding to the pre-event and post-event images. The default names are B_LabelType and A_LabelType respectively. The drop-down menu provides existing text-type fields and the option to create new ones.
    • Classification System: Defaults to empty. The user must select an existing classification system from the drop-down menu or create a new one. After setting, all category information of this classification system will be displayed below the list. In bi-temporal image annotation, the classification system automatically applies to both the pre-event and post-event label fields.
  6. After completing the above settings, click the OK button to create the image sample library. The interface will automatically switch to the Manage Image Sample tab, and the Sample window will pop up. You can start drawing sample tags or perform other analysis operations in this area.
