      You are very welcome. Glad you are finding it useful. the formula for leaf disease percentage is (diseased leaf area/Total leaf area) X 100.

    Hi can you help me understand about what to be inputted in "known distance" and "unit of length?" Because the sample we will be analyzing is the stomach of mice...we will analyze the total area of ulcers produced. I hope you will reply...we are now doing our experimental research.

      Hello, thanks for reaching out. If there is a scale image in one of your mice stomach images, that will be used as the measuring unit/length for all the subsequent images. To set the scale, first draw a line parallel to the scale. It does not matter how long it is drawn. In the above video the line is parallel to 1 cm in the scale. In the known distance input "1" since the line drawn equals 1 cm. in the unit of length input "cm" because this is a cm scale. alternatively you can also input it as 10 mm where known distance will be 10 and unit will be in mm. the distance in pixels will be set automatically. All the best with your experiment.
