Intensity Transform, Filtering &
Thresholding
(a) (b) Figure 1 (a) Intensity transformations operate on single pixels of an image for the purpose of contrast manipulation, as shown in Figure 1(a) and 1(b), respectively. Based on your understanding, explain the concept of contrast manipulation, inclusive of the commonly used formula. Please make sure to elaborate the parameters used in the formula.
