    • When first and second images are input, a partial image feature calculating unit calculates feature values of partial images of the two images. A maximum matching score position searching unit searches for a position of the second image that attains to the highest matching score with each of the partial images of the first image. A movement-vector-based similarity score calculating unit calculates similarity between the first and second images, using information related to that partial image whose movement vector has direction and length within a prescribed range, which movement vector representing positional relation between a reference position for measuring, for each of the partial images, the position of the partial image in the first image and the position of the maximum matching score corresponding to the partial image searched out by the maximum matching score position searching unit. The images as the object of collation may belong to the same category classified based on the feature values.
    • 当输入第一和第二图像时,部分图像特征计算单元计算两个图像的部分图像的特征值。 最大匹配分数位置搜索单元搜索与第一图像的每个部分图像达到最高匹配分数的第二图像的位置。 基于运动矢量的相似性评分计算单元使用与该移动矢量具有规定范围内的方向和长度的部分图像相关的信息来计算第一图像和第二图像之间的相似度,该运动矢量表示用于测量的基准位置之间的位置关系 对于每个部分图像,第一图像中的部分图像的位置和与由最大匹配分数位置搜索单元搜索的部分图像相对应的最大匹配分数的位置。 作为对照对象的图像可以属于基于特征值分类的相同类别。

    • An image comparing apparatus receives two images to be compared with each other. For each of the two images, respective feature values of partial images in the image are determined. With respect to each partial image in one of the images, the position of a partial image that is in the other image and that has the maximum score of matching with the partial image in that one image is searched for. The search range is limited to partial images selected according to three or five different feature values determined in advance. Then, the similarity score representing the degree of similarity between these two images is calculated, based on information about a movement vector indicating a relation between a reference position for locating the partial image in one image and the maximum matching score position that is searched for with respect to the partial image. Images to be searched belong to the same category as that of the partial image. Here, the images are classified into categories based on the feature values.
    • 图像比较装置接收要彼此比较的两个图像。 对于两个图像中的每一个,确定图像中的部分图像的各自的特征值。 对于其中一个图像中的每个部分图像,搜索位于另一图像中并且具有与该图像中的部分图像匹配的最大分数的部分图像的位置。 搜索范围限于根据预先确定的三个或五个不同特征值选择的部分图像。 然后,基于关于指示用于定位一个图像中的部分图像的参考位置与用于定位一个图像中的部分图像的最大匹配分数位置之间的关系的运动矢量的信息,计算表示这两个图像之间的相似度的相似度分数, 尊重部分图像。 要搜索的图像属于与部分图像相同的类别。 这里,基于特征值将图像分类为类别。

    • A self-synchronous logic circuit includes scan test compliant registers holding data and forming stages of a pipeline, and scan test compliant self-synchronous signal control circuits corresponding to respective registers and performing handshake to transfer clocks. In accordance with the clocks transferred by the scan test compliant self-synchronous signal control circuits, data processing among the scan test compliant registers proceeds. In addition to normal data processing, the scan test compliant registers have a function of serially transferring contents thereof at the time of a test. The scan test compliant self-synchronous signal control circuits are set to a state that corresponds to the end of a third way of the handshake, at the time of a test.
