    • An image recognition method and device detects an object mark reliably even when the mark is defaced with a different color. RGB signals are transmitted to color extraction unit. The color extraction unit has a characteristic color extraction block to extract the characteristic color of the object mark. A binary image is generated from the extracted pixels which are the color of the mark and stored in storage device. A mark detection unit detects the location of the mark in the stored image data and an image extraction unit extracts the region where the mark is located and obtains a feature count. A matching unit compares the feature count with a reference pattern and finds the goodness of fit. A control unit subjects the goodness of fit value to threshold value processing to determine whether this is a nonreproducible document. If the mark has been defaced with black ink, the pixels constituting the mark are extracted by a likely color extraction block. A binary image is generated and stored in storage device. Thus, the defaced mark can undergo the same recognition processing as the normal mark, and both can be recognized.
    • 即使当标记被不同颜色污染时,图像识别方法和装置可靠地检测对象标记。 RGB信号被传送到颜色提取单元。 颜色提取单元具有特征颜色提取块,以提取对象标记的特征颜色。 从作为标记的颜色的提取像素生成二值图像并存储在存储装置中。 标记检测单元检测所存储的图像数据中的标记的位置,并且图像提取单元提取标记所在的区域并获得特征数。 匹配单元将特征计数与参考模式进行比较,并找到拟合优度。 控制单元对拟合值进行阈值处理,以确定这是否是不可再现的文档。 如果标记已被黑色油墨弄脏,则构成标记的像素由可能的颜色提取块提取。 二进制图像生成并存储在存储设备中。 因此,污损标记可以进行与正常标记相同的识别处理,并且都可以识别。
