    • An image processing apparatus includes a comparison unit that selects a pixel of interest in a processing image, and compare magnitudes of luminance value of the pixel of interest and luminance value of each of a plurality of neighboring pixels having a predetermined positional relationship with the pixel of interest; a calculation unit that calculates a feature amount of the pixel of interest based on the predetermined positional relationship between the pixel of interest and each of the plurality of neighboring pixels and a comparison result obtained by the comparison unit. For two neighboring pixels at positions which are point symmetrical with respect to the pixel of interest, the comparison unit sets that only one of the two neighboring pixels has the predetermined positional relationship.

    • Even when a local area is varied, degradation in recognition accuracy and detection accuracy is suppressed. To that end, a pattern processing apparatus includes a reference local area setting portion 1802 for setting a reference local area based on the detection result of a feature point by a face organ feature point detecting portion 101, a varied local area generating portion 1803 for generating a plurality of varied local area patterns by referring to an image area near the reference local area, a similarity calculating portion 106 for calculating similarities in the reference local areas and in the varied local area patterns between the input pattern and the registered pattern, a representative similarity calculating portion 107 for calculating representative similarity from among the similarities, and a classifying portion 109 for determining a class to which the input pattern belongs.
    • 即使局部区域变化,也能够抑制识别精度和检测精度的劣化。 为此,图案处理装置包括:基准局部区域设定部1802,用于基于面部特征点检测部101的特征点的检测结果来设定基准局部区域;变化的局部区域生成部1803, 通过参考参考局部区域附近的图像区域的多个变化的局部区域图案,计算参考局部区域和输入图案与登记图案之间的变化的局部区域图案中的相似度的相似度计算部分106, 相似度计算部分107,用于从相似度中计算代表性相似度;以及分类部分109,用于确定输入模式所属的类别。
