Calculate the digital negative of the following 8-bits per pixel (BPP image).

(i) Digital Negative Digital negatives are useful in a lot of applications. A common example of digital negative is the displaying of an X-rav_image. As the name suggests, negative simply means inverting the gray levels, i.e., black in the original image will now look white and vice versa Figure 2.5 is the digital negative transformation for a 8-bit image. The digital negative image can be obtained by using a simple transformation given by 255 Original gray level, r Fig. 2.5 Digital Negative.
