4.1.3. Creating a 3-Class Annotated Dataset

We also annotated a 3-class dataset. Numerals, register updates and background are the target classes. We aim to analyze the effect of adding register update class to the numeral spotting performance. Numerals were colored as green; updates were colored as red. The background is black which is the same as the 2-class annotation (see Figure 5).

**Figure 5.** In part (**a**), the masked figure is shown. In part (**b**), the 3-class annotated image and in part (**c**), the prediction of our model (updates and numerals vs. background) are shown.
