    Abstract: A method for managing a display of an electronic document (ED) on a display screen includes obtaining the ED specifying a plurality of text and a first graphical element; identifying a starting reference and an ending reference to the first graphical element within the plurality of text; displaying a portion of a segment of the plurality of text in a first region of the display screen, the segment being located between the starting reference and the ending reference; displaying, while displaying the portion of the segment, the first graphical element within a second region of the display screen, wherein the second region is adjacent to the first region on the display screen; removing the segment from the first region; and removing the first graphical element from the display screen in response to removing the segment such that the first region expands into the second region.

    Abstract: A method for processing an image with a processor, including: identifying, within an image, a candidate arrow including a long path adjacent to a plurality of short paths; determining a direction of the candidate arrow based on the long path; estimating a tip pixel within the plurality of short paths based on the direction of the candidate arrow; determining, for the candidate arrow, a plurality of arrowhead edges in the plurality of short paths based on the tip pixel; and generating, for the candidate arrow, a plurality of refined arrowhead edges based on the plurality of arrowhead edges, the direction, and the tip pixel.

    Abstract: A method for processing an original image. The method includes: obtaining the original image of a writing board; identifying, within the original image, a first stroke by identifying a first plurality of pixels that exceed at least one intensity threshold; determining a geometric feature of the first stroke; selecting a region of the original image adjacent to the first stroke based on the geometric feature; determining an additional pixel in the region that corresponds to the first stroke; and adding the additional pixel to the first plurality of pixels. The first plurality of pixels correspond to the first stroke.
