    • A radiographic image processing apparatus in this invention decreases a spatial resolution twice in total by a low-frequency image generating device and a low-frequency characteristic generating device. Thereby an influence such as noise and thus calculation amounts are decreased. Moreover, excessive characteristic amounts (patterns) not removed among characteristic amounts extracted through the low-frequency image generating device and a characteristic extracting device can be decreased by decrease of the spatial resolution by the low-frequency characteristic generating device. Consequently, influence such as noise and calculation amounts can be decreased for the low-frequency characteristics generated by the low-frequency characteristic generating device and a radiation area extracted by an area extracting device on the latter stage. As a result, influences such as noise can be decreased for achieving characteristic extraction and area extraction with high accuracy, and thus calculation amounts can be decreased.
    • 本发明的放射线照相图像处理装置通过低频图像生成装置和低频特征生成装置将空间分辨率总共降低了两倍。 因此,减少了诸如噪声和因此计算量的影响。 此外,通过低频特征产生装置的空间分辨率的降低,可以减少通过低频图像产生装置和特征提取装置提取的特征量中未被去除的过多的特征量(图案)。 因此,对于由低频特征产生装置产生的低频特性和由后级的区域提取装置提取的辐射面积,可以降低诸如噪声和计算量的影响。 结果,为了实现高精度的特征提取和区域提取,可以降低噪声等影响,能够减少计算量。
