Quiz sheets are commonly used to measure students' learning outcomes. These sheets typically include test answers and grading marks made during review sessions. To make it easier to review and practice the questions again, it is suggested that these elements be removed and only the questions be kept on the quiz sheet. In this work, we propose using the Text Separation with Binarization Feature model (TSBFM) to identify the positions of the printed questions on the sheet. During the evaluation of model performance, we conducted tests on the self-collected dataset NtutQuizSheet. Our solution has shown an improvement of 7.81% in IoU metrics when compared to previous methods.
