Q1. Many image editing effects can be created by simple image arithmetic and straightforward matrix manipulations. For example, Solarization is a photographic effect in which the image appears partly positive and partly negative, as shown below A simple solarization effect can be created by taking the complement of pixels in an image whose intensity values are less than 128. If your image is stored in variable I and x and y represent, rows and cols, then I(x,y)=I(x,y) if I(x,y)128 I(x,y)=255I(x,y) if I(x,y)
