发明名称 Compression of digital ink
摘要 Compression of digital ink is achieved by calculating second order differences between consecutive elements in the digital ink and applying the differences to a Huffman encoder to produce a compressed bitstream. For digital ink that is not highly correlated, compression may be achieved by representing segments of the digital ink by mathematical shapes such as a Bezier curve or orthogonal elements and transmitting the shape instead of the digital ink.
