Abstract (en)
[origin: WO2020210637A1] A system for capturing, organizing, and storing handwritten notes includes a plurality of boundary markers. The boundary markers are configured to be positioned on a writing surface. Furthermore, the plurality of boundary markers have a fluorescent color. The system also includes a tangible non- tiansitory computer readable medium encoded with instructions which, when run on a camera-equipped computing device, causes the camera-equipped computing device to execute processes. The processes include capturing an image of the writing surface with the fluorescent markers thereon. The processes also include detecting the fluorescent colored boundary markers in the captured image. Additionally, the processes include identifying a virtual boundary in the captured image based on the positions of the fluorescent colored boundary markers. The processes then unwarp a portion of the captured image within the virtual boundary to produce an unwarped image.
