问如何在Matlab中将一维RGB图像重塑为二维RGB图像？

EN

I = [r1 r2 ... rN; g1 g2 ... gN; b1 b2 ... bN];

N = H*W;

I2(1,1,1) = r1
I2(1,1,2) = g1
I2(1,1,3) = b1
I2(2,1,1) = r2
I2(2,1,2) = g2
I2(2,1,3) = b2
...
I2(H,W,1) = rN
I2(H,W,2) = gN
I2(H,W,3) = bN

R = I(1,:);
R = reshape(R,H,W);

G = I(2,:);
G = reshape(G,H,W);

B = I(3,:);
B = reshape(B,H,W);

I2 = cat(3, R, G, B);
