- To start, click on "New Annotations" button on the top right
- Draw a bounding box around a text region
- A new window will pop up
- Here you can select whether this text is machine-printed or handwritten
- In the text area, input the text within the bounding box
- Press "Done" when finished.
Figure 1. Click on the "New annotations" to start the process
Figure 2. Drawn bounding box and information filled. Click "Done" to finish.
Figure 3. A complete example. The text area in the right illustrates the information that is going to be sent back to the back-end server of choice.Interactions:
- Draw bounding boxes around text
- Resize and move the bounding boxes
- Input and modify the texts for the drawn bounding box by clicking on the bounding box
- Delete bounding box
- Allows easy annotations of texts and data
- Easy interface with other system (Mechanical Turk, ZooUniverse, etc.)
- Easy access - web interface - no installation required.
Before reading the next part, please take a few minutes and experience the interface. The next section will make more sense.
- Using computer vision and machine learning to streamline the process
- Use automatic text detection for automatic bounding boxes localization
- Use OCR to automatically fill in the text box section
- Use word spotting algorithm to deal with tough cases
- A time measurement mechanism to evaluate the performance of the interface.
In the next blog post, we will describe the use of text detection in assist of automatically localizing bounding boxes.
