Mid-Level Vision: Segmentation (Artificial) 1. Briefly describe the role of mid-level vision. To group together image elements that belong together, and to segment them from all other image elements. 2. One simple method of segmentation is thresholding. (a) Briefly explain how an appropriate threshold might by obtained by using an intensity histogram. (b) Explain the
