Abstract
A method comprising obtaining image data representative of pixel intensities associated with an image. Irrespective of a respective magnitude of the pixel intensities, the image data is processed with a logarithmic transformation to transform the pixel intensities to transformed pixel intensities, thereby generating transformed image data representative of the transformed pixel intensities. The logarithmic transformation, L(x), is representable as:()=log(())+where x represents a pixel intensity to be transformed, f(x) represents a function of x and P, M and N represent constants.
