对信号点不加处理，灰度值不变。
用图像分析仪分别测各组阳性信号的灰度值作定量分析。
Image analytic system was used to detect the gray degree values of the positive signals.
其关键步骤包括：图象滤波，图象灰度信息提取，微阵列间距确定，靶点定位和靶点信号值计算。
This algorithm includes image filtering, extracting gray information, determining microarray spacing, addressing of spots and calculating brightness property from spots.
如果图像中仍然存在人的噪声团块，则噪声用相邻的三个信号点的灰度均值替换。
If the image still exists in clumps of the noise, the noise replace the gray average of the three adjacent signal points.
其中灰度直方图法是本系统告警信号灯识别的最佳方法。
The gray histogram arithmetic is the best method for this system.
该算法是先对有意义的灰度图像进行水印序列化处理后，再将其作为水印信号嵌入到载体图像的分块DCT系数直流分量里。
The meaningful gray image is serially processed into watermark signal and embedded into the DC elements of the block DCT coefficient matrix of the host image.
