Extracted text: Figure 3(a) b) Assume that you have successfully obtained the mask shown in Figure 3(a), suggest an approach that can be used to count the number of T-shape objects (the three objects labelled with A, B, and C in Figure 3(i) respectively). Explain your approach in detail and justify if your approach can still work if the size of the T-shape objects is not the same. State clearly any assumption(s) you made.
