I HAVE CONVERTED AN IMAGE FROM RGB TO LAB AND SELECTED B COMPONENT TO APPLY FAN BEAM TRANSFORM...BUT I AM GETTING 361*360 WHICH CAN NOT BE DIVIDED INTO SQUARE MATRIX

C = imread('lena.png');

lab = rgb2lab(C);

L=lab(:,:,3);

imshow(L);

output_size = max(size(L));

D = 315.25;

dsensor3 = 0.1985;

[F3, sensor_pos3, fan_rot_angles3] = fanbeam(L,D,...

'FanSensorSpacing',dsensor3);

imshow(F3);

Ifan3 = ifanbeam(F3,D,'FanSensorSpacing',dsensor3,'OutputSize',output_size);

figure, imshow(Ifan3)

I want to divite the F3 into 4*4 block...but the size of F3 i am getting is 361*360....now what can i do?

Either crop it, enlarge it, or resize it.
