摘要： A transaction document reader reads image data on a transaction document. The image data includes marking areas employed by a user to record marks and includes characters. A sensor senses, one row at a time, rows of image data as the document is transported across the sensor. Each row includes a number of pixel areas. The pixel areas of the rows being aligned in columns. The sensor generates output signals representative of the pixel areas. The output signals are transformed into bit signals representative of each pixel area. The bit signals are stored in image memory which is organized into rows and columns of bit signals corresponding to the rows and columns of the pixel areas of the image data. The marking areas are located in image memory. The marks are identified in the marking areas while additional rows of bit signals are being stored and while other marking areas are being located by probing the bit signals in image memory. A specific area within image memory representative of a single character is also located. A neural network is utilized to recognize the character within specific area.

摘要翻译： 交易文档读取器读取交易文档上的图像数据。 图像数据包括用户用于记录标记并包括字符的标记区域。 当传感器传感器传输文档时，传感器一次一行地检测图像数据行。 每行包括多个像素区域。 行的像素区域在列中对齐。 传感器产生代表像素区域的输出信号。 输出信号被变换成表示每个像素区域的位信号。 位信号被存储在图像存储器中，其被组织成与图像数据的像素区域的行和列相对应的位信号的行和列。 标记区域位于图像存储器中。 在标记区域中识别标记，同时存储附加的位信号行，并且通过探测图像存储器中的位信号来定位其它标记区域。 位于图像存储器内的代表单个字符的特定区域也被定位。 使用神经网络来识别特定区域内的角色。
