量化单元

a quantization unit configured to generate edge image data by performing a quantization process on the edge intensity image data,

量化单元，用于通过对边缘强度图像数据进行量化过程而生成边缘图像数据，

The edge labeling unit 203 regards edge pixel regions having connectivity on the edge image data generated by the quantization unit 202 as the same region, and performs a process of giving the same label number to edge pixels in the same region and thereby generates labeled image data.

边缘标记单元203将在量化单元202生成的边缘图像数据上具有连通性的边缘像素区域视为同一区域，进行对同一区域的边缘像素提供相同标记号码的过程，从而生成标记图像数据。

The fine object removal unit 205 performs a noise removal process on the edge image data generated by the quantization unit 202 and the labeled image data generated by the edge labeling unit 203, and thereby generates output edge image data and output labeled image data.

对象精细清除单元205对量化单元202生成的边缘图像数据和边缘标记单元203生成的标记图像数据进行噪声消除过程，从而生成输出边缘图像数据和输出标记图像数据。

Further, the image processing unit may have an edge extraction unit configured to generate edge intensity image data by performing an edge extraction process on the captured image data, a quantization unit configured to generate edge image data by performing a quantization process on the edge intensity image data, an edge labeling unit configured to regard edge pixel regions having connectivity with the edge image data as a same region, to perform a process of giving a same label number to edge pixels of the same region, and to generate labeled image data, a first rectangle objectification unit configured to perform a process of giving a circumscribed rectangle to the edge pixel regions to which the same label number is given based on the labeled image data, and to generate a rectangular object, and a first fine object removal unit configured to perform a process on the edge image data to remove an edge pixel region having a small number of connected pixels and an edge pixel region in a rectangular object having short vertical and horizontal widths as noise based on the labeled image data and the rectangular object, and to generate output edge image data.

进一步，图像处理单元可具有：边缘提取单元，用于通过对捕捉图像数据进行边缘提取过程而生成边缘强度图像数据；量化单元，用于通过对边缘强度图像数据进行量化过程而生成边缘图像数据；边缘标记单元，用于将与边缘图像数据具有连通性的边缘像素区域视为同一区域，进行对同一区域的边缘像素提供相同标记号码的过程，并生成标记图像数据；第一矩形对象化单元，用于基于标记图像数据进行对具有相同标记号码的边缘像素区域提供外切矩形的过程，并生成矩形对象；第一对象精细清除单元，用于基于标记图像数据和矩形对象对边缘图像数据进行该过程：将连接像素数量少的边缘像素区域以及矩形对象内垂直和水平宽度短的边缘像素区域作为噪声而清除，并生成输出边缘图像数据。
