Let V= {0, 1, 2, 3, ..., 49). There is a path based on 4-adjacency on V, which starts at pixel (140) and ends on the opposite side of the image. What is the location of the last pixel of that path? 2. What is the intensity value of the last pixel of this path? 3. Shade this path with a pencil or, if done electronically, with yellow highlight color. 4. Starting at pixel (22. 14) there is a dark (almost black) path, which comes back to pixel (22, 14). What do we call such paths? 5. What is set V in this case? 6. What kind of adjacency do you observe? 7. What is the length of that path in number of pixels? 8. The enclosed set of pixels (called "region" in Image Processing terminology) is very light (almost white). What gray-scale values does this region contain? 9. In relation to the region, what do we call the enclosing path
