Abstract:
An image identification apparatus for identifying an image from a sequence of spatial samples generated in response to a hand drawn representation of said image, said image identification apparatus comprising:a drawing processor having a drawing tool for use in creating said hand drawn representation of said image, wherein said sequence of spatial samples is generated in accordance with movement of said drawing tool, a segment processor arranged in operation to determine from said spatial samples stroke data representative of strokes performed in drawing said hand drawn representation of said image, a stroke pre-processor which is arranged in operation to generate parameter data from said sequence of spatial samples and the determined stroke data of the hand drawn representation, and an image identifier coupled to said stroke pre-processor which is arranged in operation to identify said image from the parameter data, wherein said segment processor operates to determine said stroke data by generating from said spatial samples relative direction information representative of a relative direction of said drawing tool, determining from said relative direction information a number of changes of direction of said tool, and determining said strokes of the hand drawn representation in accordance with the number of changes of direction.
