Figure 2. The parts of an ICT kit (left) and reference colour card (right) (a). An ICT kit showing a positive result (b) with a band at both control (C) and test (T) lines. An ICT kit showing a negative result (c) with a band only at the C line. The intensity value of the colour image is specified by the red, green, and blue parameters as separate integers from 0 to 255 with the 8-bit representation of a pixel in the image. The intensity values were plotted for C and T lines of the positive (d) and negative (e) ICT kits. The intensity values (d and e) were related to colour band intensity of C and T lines in the strips. S indicates sample hole.图2 (a)：左侧为免疫层析试剂盒（ICT）各组成部件，右侧为标准色卡。(b)为呈阳性结果的ICT试剂盒，其对照线（C）与检测线（T）均出现显色条带。(c)为呈阴性结果的ICT试剂盒，仅对照线（C）处出现显色条带。彩色图像的亮度值由红、绿、蓝三个通道参数分别定义，各参数为取值范围0至255的整数，对应图像像素的8位表示格式。针对阳性(d)与阴性(e)ICT试剂盒的对照线（C）与检测线（T），绘制了其亮度值分布曲线。图(d)与(e)中的亮度值与试纸条上对照线（C）及检测线（T）的色带亮度相关。S代表样品加样孔。
