Question

PLEASE make sure it's correct!

Assume binary image BW1 above is 200 (rows) by 300 (columns) pixels Which of the following images shows no white pixels (that is, contains all black pixels)? BW2 = BW1(50: 100,:): imshow(BW2) BW2 = BW1(50: 100, 1: 100): imshow(BW2) BW2 = BW1(100: 110, 100: 200): imshow(BW2) BW2 = BW1(: 1: 200): imshow(BW2)

Answer 1

Binary image BW1 above is 200(rows) by 300(columns) BW2= BW1(50:100,:); imshow(BW2) shows no white pixels(that is contain all black pixels)

Choose option 1.

BW2= BW1(50:100,:);

Here BW2 no white pixelsbecause we can extract the pixels which contain all black pixels.

50:100 CORROSPONDS to the black pixels.
