WitrynaA logarithmic transformation is a transformation where every data-value (x) is re-calculated in a logarithmic form (log (x), or more aptly, ln (x)). Logarithms have a lot of unique properties, such as turning multiplicative operations into addition. This aspect of logarithms is so important, as it allows exponential data to be viewed linearly ... WitrynaThe logarithmic transform of a digital image is given by s=T (r) = c*log (r+1) 's' is the output image 'r' is the input image When logarithmic transformation is applied onto a digital image, the darker intensity values are given brighter values thus making the details present in darker or gray areas of the image more visible to human eyes.
