3- (20 points) Consider the 4x4 image below, determine the bilinear upscaled (zoomed) image by a factor R=2. Propose an approach that makes sense to obtain an 8x8 image so that is R-2 times bigger in the x and y directions. Below you have a larger 9x9 table, justify your choice of an 8x8 subset too. 0000 30 60 30 60 120 60 30 60 30 0 0 0 ANSWER: 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 30 0 0 60 0 30 0 30 60 30 ANSWER: b) Propose a 3x3 spatial filtering mask to accomplish a bilinear interpolation by R-2 using as input a zero-filled image like this one. 0 0 0 0 0 0 0 0 0 0 0 20 60 60 0 120 0 60 0 120 60 0 0 0 0 0 0 0 0 0 0 30 0 60 0 0 30 0 30 60 30 0 0 0 0 0 0 0 0 3- (20 points) Consider the 4x4 image below, determine the bilinear upscaled (zoomed) image by a factor R=2.
