Item Classification
Item Classification Features
Auto Next Item
When the task requires only a single class per image, enabling the “Auto next item” feature will automatically load the next item as soon as a class is selected, to save time.
Auto Complete
Enabling “Auto complete” (shown only after ‘auto next item’ is checked) will automatically set an image item to ‘Completed’ status when moving to the next item.
Bulk Classification
Rapid and highly efficient item (image/video) classification can be done in bulk from the Task or assignment browser. To work in bulk classification:
- A manager should enable 'Bulk classification' mode from the recipe settings
- Double click an assignment and it will redirect to the assignment-browser, and not the annotation-studio
- Select items (CTRL+Mouse click) you want to classify.
- Click on the classification tool icon
- Select a class from labels list, and approve the action by one of the 2 options
- Classify - Simply adds the class to the item, but does not change its status
- Classify & Set Status - Adds the classification and opens a drop-down to select which status to add to the item (e.g COMPLETED by default, unless custom statuses were added to the task).
Bulk classification requires that all items are allocated to an assignment, and therefore it disabled when the task is a "Pulling" based task, where items are pulled by assignees during work, and not in advance. Use only "Allocation" tasks for bulk classification work.
Video Scene Classification
Classifying a video scene is similar to how images are classified, with the main difference that a scene has Start and End times.
- To classify scenes in a video, navigate to the first frame and click on the label. The annotation will be created with the 'START' keyframe and last until the very last frame of the video.
- Continue skipping frames until you reach the end of the scene and set the frame as the end time to conclude the annotation. See how to set the end time here.
- Alternatively, if you want to use that label again, you can simply hide it for a number of frames and unhide it once you need it again. Learn more about hidden frames here.
* Available on image and video items
The Classification tool enables labeling/annotating an entire image or scene (in the case of a video file). For example, classification can be used to classify product images under categories, subcategories, and characteristics, such as men’s clothes, polo shirts, etc.
The Dataloop system has several important features designed to increase the productivity of classification annotation tasks.
