FIELD: physics; image processing.
SUBSTANCE: present invention relates to a system and method for recognition of objects handwritten in ink. A detection unit can detect a handwritten figure, such as diagram or graph by detecting closed containers and (or) open connecting links on the figure. To adjust handwritten lines to the image grid with corresponding dimensions, an efficient method based on using the image grid can be used. A filling algorithm can be used to detect containers and connecting links. After spatial searching, time search can also be carried out so as to process overlapping drawn lines. Finally, content for each detected container can be identified. Once containers and their associated content are detected on the image grid, connecting links can then be detected.
EFFECT: invention allows for detecting and recognising shape of handwritten objects regardless of the order in which lines were made and (or) regardless of the number of lines required for formation of any given shape.
