    • Object detection apparatus includes storage unit storing learned information learned previously with respect to sample image extracted from an input image and including first information and second information, first information indicating at least one combination of given number of feature-area/feature-value groups selected from plurality of feature-area/feature-value groups each including one of feature areas and one of quantized learned-feature quantities, feature areas each having plurality of pixel areas, and quantized learned-feature quantities obtained by quantizing learned-feature quantities corresponding to feature quantities of feature areas in sample image, and second information indicating whether sample image is an object or non-object, feature-value computation unit computing an input feature value of each of feature areas belonging to combination in input image, quantization unit quantizing computed input feature value to obtain quantized input feature value, and determination unit determining whether input image includes object, using quantized input feature value and learned information.
    • 对象检测装置包括存储单元,存储先前关于从输入图像提取的样本图像学习的学习信息,并且包括第一信息和第二信息,第一信息指示从特征区域/特征值组中选择的给定数量的特定区域/特征值组的至少一个组合 每个特征区域/特征值组包括特征区域之一和量化的学习特征量之一,每个具有多个像素区域的特征区域以及通过量化与特征相对应的学习特征量而获得的量化的学习特征量 样本图像中的特征区域的量,以及指示样本图像是对象还是非对象的第二信息,特征值计算单元计算属于输入图像中的组合的每个特征区域的输入特征值,量化单元,计算输入 特征值以获得量化的输入特征值,并确定 国家单位确定输入图像是否包括对象,使用量化输入特征值和学习信息。
