Like Shaun has pointed out, open the image into an RGB (colour) image buffer to store the image, then threshold the image using IMAQ Color Threshold.vi so that the range of blue (0-120) is replaced by 255 (white). Take a look at this example for more details: … WitrynaOften only 256 bytes of memory needed. Thus, selected threshold values minimize both effects. From various experiments car- ried out, the optimal threshold value found is 112 as shown in Table 2. From experimental results, it is observed that the image with threshold value (TV) bigger and smaller than 112 generates darker and brighter images.
