I tried really hard, but could not perform the above mentioned steps in ImageJ. Put a check in Threshold and Invert-then press the sample button. Journal of Histochemistry & Cytochemistry. Recall that RGB images are actually the composite of three separate images having intensities from the darkest to lightest of Red, Green, and Blue colors. I adjusted the necessary color thresholding but one of the protocol says that I need to. "Automatic measurement of sister chromatid exchange frequency". ^ Zack, G W Rogers, W E Latt, S A (July 1977). In difficult cases, thresholding will likely be imperfect and yield a binary image with false positives and false negatives. higher intra-class variance than inter-class variance, i.e., pixels from a same group have closer intensities to each other than to pixels of another group,. 
Thresholding will work best under certain conditions : Most of the binary automatic thresholding methods have a natural extension for multi-thresholding.
The simplest thresholding methods replace each pixel in an image with a black pixel if the image intensity I i, j. From a grayscale image, thresholding can be used to create binary images.
In digital image processing, thresholding is the simplest method of segmenting images. The binary image resulting from a thresholding of the original image.
