发明名称 Image processing apparatus, image processing method and program
摘要 A model is defined by a plurality of first positions on an edge extracted from a model image and a changing direction of the edge in each of the first positions. An image processing apparatus calculates a changing direction of an edge in a second position of an input image corresponding to the first position on the edge of the model image. The image processing apparatus accepts an instruction associated with a permissible value of the changing direction of the edge. The image processing apparatus calculates a similarity degree of the first position and the second position corresponding to the first position based on the accepted instruction, the changing direction of the edge in the first and second position. The image processing apparatus determines whether a specific area in the input image is similar to the model or not based on the calculated similarity degree in the second positions.

主权项 1. An image processing apparatus configured to search a similar area to a previously registered model from an input image, the model being defined by a plurality of first positions on an edge extracted from a model image and a changing direction of the edge in each of the first positions, the image processing apparatus comprising: a first calculator configured to calculate a changing direction of an edge in a second position of the input image corresponding to the first position; an acceptor configured to accept an instruction associated with a permissible value of the changing direction of the edge; a second calculator configured to calculate a similarity degree of the first position and the second position corresponding to the first position, based on the accepted instruction and the changing direction of the edge in the first position and the changing direction of the edge in the second position; and a first determining unit configured to determine whether a specific area in the input image is similar to the model or not based on the similarity degree calculated between the first position and the second position corresponding to the first position.
