Question 2. How can a method be developed to eliminate small-scale defects such as scratches and to fill large-sized regions, such as objects, in color photos that contain texture information as well as structural information? What could be the similarities with the noise attenuation approaches you could suggest? Also, what advantages and disadvantages might arise in the method of motion estimation that can be expected when any object in a motion picture sequence without scene transition is destroyed, compared to actions taken considering a single picture? Explain in detail.
