Abstract
A method of analysing an image to obtain an image value. The image comprises a defined array of pixel values. The method comprises(1) determining the highest pixel value in the image;(2) calculating a lower threshold pixel value from the highest pixel value determined in step (1) in accordance with a predetermined algorithm; and(3) obtaining the image value by statistically analysing the pixel values in the image which lie in a range defined by the lower threshold pixel value calculated in step (2).
