| Abstract(in English) | The lecturers can use their body movements and gestures in the lectures with slides displayed using a projector in the real world. However, recording these slides with a video camera has issues with the visibility of the slides. Our previous study improves the quality of the lecture slides in videos by overlapping the digital slides in the virtual space with the projected slides in the real space. In addition, we realized writing on the virtual slides with real stationery. However, there was room for improvement in the visibility of the handwritten content. The purpose of this paper is to restore the projected slides to the original slides to improve the image quality. We propose a method to improve the image quality by adjusting pixel values of projected slides based on white color. In evaluation experiment, out method verified an improvement in the image quality by comparing original projected slides with the restored slides. |
