This example shows how to divide twouint8arrays.

X = uint8([ 255 0 75; 44 225 100]); Y = uint8([ 50 50 50; 50 50 50 ]);

Divide each element inXby the corresponding element inY. Note that fractional values greater than or equal to 0.5 are rounded up to the nearest integer.

Z = imdivide(X,Y)

Z =2x3 uint8 matrix5 0 2 1 5 2

Divide each element inYby the corresponding element inX. Note that when dividing by zero, the output is truncated to the range of the integer type.

W = imdivide(Y,X)

W =2x3 uint8 matrix0 255 1 1 0 1

Read a grayscale image into the workspace.

I = imread('rice.png');

估计背景。

background = imopen(I,strel('disk',15));

Divide out the background from the image.

J = imdivide(I,background);

Display the original image and the processed image.

imshow(I)

figure imshow(J,[])

Read an image into the workspace.

I = imread('rice.png');

Divide each value of the image by a constant factor of 2.

J = imdivide(I,2);

Display the original image and the processed image.

imshow(I)

figure imshow(J)
