Abstract

"SISTEMA E MéTODO PARA RECONHECIMENTO DE FORMA DE OBJETOS DESENHADOS à MãO". Um sistema e método para reconhecimento da forma dos objetos desenhados à mão são proporcionados. Um identificador de forma pode reconhecer um desenho tal como um diagrama ou gráfico a partir da entrada de tinta reconhecendo recipientes fechados e/ou conectores abertos no desenho. Os recipientes fechados podem representar qualquer número de formas que possam ser reconhecidas incluindo círculos, elipses, triângulos, quadriláteros, pentágonos, hexágonos e assim por diante. Os conectores abertos podem ser qualquer tipo de conector incluindo linhas, curvas, setas e assim por diante. Polilinhas podem ser usadas para aproximar um esboço de um conector para manipular traços de continuação, traços de sobreposição e traços de sobre-traço do esboço. Pelo uso da presente invenção, um usuário pode desenhar diagramas e fluxogramas livremente e sem restrições sobre a entrada desenhada à mão.
