3. What Is Geometric Transformation?

Image translation


Image rotation


4. What Is Meant By Mach Band Effect?

Answer: Mach band effect means the intensity of the stripes is constant. Consequently, it preserves the brightness pattern near the boundaries; these bands are called as mach band effect.


5. Define Digital Image?

Answer: When x, y and the amplitude values of  all are finite discrete quantities , we call the image digital image.
