Create Image Sample Library

Feature Description

The image sample library is the core container for organizing and managing sample images, vector labels, and the classification system. By creating a sample, you can specify the annotation type (single-phase/bitemporal), add images, and configure the corresponding vector label dataset, laying the foundation for subsequent sample annotation and deep learning model training. After the sample library is created, the Manage Image Sample view is activated for centralized annotation operations.

Function 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 to open the Create a New Image Sample Library dialog box.
  2. Set the image sample library name. The default is SampleImage. If a sample library with the same name already exists in the system, the suffix "_n" is automatically added to distinguish it (e.g., SampleImage_1, SampleImage_2).
  3. Select the dimension type:
    • Single-phase image: Annotate a single image, providing only one annotation window.
    • Bitemporal image: Provides windows for both the antecedent image and the aftertime image, supporting simultaneous annotation on the other temporal image when annotating the antecedent or aftertime image, suitable for change detection scenarios.
  4. Add sample images based on the selected annotation type.
    • Single-phase image: Supports four methods: Add File, Add Folder, Add List, and Add Dataset. Add Dataset includes mosaic dataset, read-only image data opened in the current workspace, and imported image data.
    • Bitemporal image: The list is divided into two columns: Antecedent Image and Aftertime Image. You must specify the corresponding aftertime image for each antecedent image before confirming the creation.
      • Add List: Requires selecting the antecedent image manifest file and the aftertime image manifest file separately. The system automatically matches the before and after temporal image pairs by row number. The antecedent image list is required; the aftertime image can be specified manually.
      • Other addition methods: The default is to add antecedent images. You need to manually specify the corresponding aftertime image for each antecedent image in the list.
  5. Set the sample tag: Configure the vector dataset used to store annotation results. Manage the list using the Add, Select All, Invert Selection, and Delete buttons on the toolbar. The sample tag list header descriptions are as follows:
    • Datasource: Defaults to the data source currently selected in the Workspace Manager.
      • If not selected, the first data source in the Workspace Manager is used.
      • If no open writable data source exists in the Workspace Manager, it defaults to empty.
      • The drop-down list contains all writable data sources and supports opening and creating a new datasource.
    • Dataset: Defaults to empty. The drop-down list provides all region datasets from this data source and supports creating new ones.
    • Label Field: Configure the field storing label object property information.
      • Single-phase image: A text field named LabelType is created by default. The drop-down menu supports selecting an existing text field or creating a new field.
      • Bitemporal image: Set the Pre-time Label Field and the Post-time Label Field respectively, corresponding to the antecedent image and aftertime image. The default names are B_LabelType and A_LabelType. The drop-down menu provides existing text fields and a new field creation option.
    • 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 categories of this classification system are displayed below the list. In bitemporal image annotation, the classification system is automatically applied to the pre-time and post-time label fields.
  6. After completing the above settings, click the OK button to create the image sample library. The view automatically switches to the Manage Image Sample tab, and the Sample window appears. You can start drawing sample tags or perform other analysis operations in this area.
