Assume imdata is a variable containing 2D (i.e., gray scale, not RGB) image data

Question

Assume imdata is a variable containing 2D (i.e., gray scale, not RGB) image data. The following statements have just been executed: [m, n] = size (imdata); mid1 = m/2; mid2 = n/2; A matrix index cannot be a fraction. Rewrite the assignment statement for mid1, to accommodate the fact that m might be an odd number. Using imdata, mid1 and mid2, write the assignment statement for Q3, the image data for the region Hw7_8 refers to as "Quadrant 3". Assume imdata2 is a variable containing RGB image data. Write the assignment statement for blue, the matrix of values for the entire blue layer.

Explanation / Answer

6.
[m n] = size(imdata)

mid1 = floor(m/2);
mid2 = floor(n/2);

7. reference to Q3 is missing

8. imdata2(:, :, 2) %repsresents blue layer
