Image processing with Matlab : (3)(create function,Binary photo,Crop image,Rotate)

• Create function in Matlab 

function [ output_args ] = functionName( input_args )

imshow(input_args);

end

• Automatic alignement of code lines in editor, do EDIT->Select ALL, then TEXT -> Smart INDENT

• Create Own Photo (Binary)

col=256;

row=256;

img=zeros(row,col);

img(100:100,:)=1.5;

img(:,100:100)=1.5;

imshow(img);

• Crop an Image 

a=imread('abc.jpg');

i=imcrop(a);

imshow(i)

• rotate an image in Matlab and Subplot

a= imread ('abc.jpg');

i = imrotate(a,180,'bilinear');

i2 = imrotate(a,45,'nearest');

subplot(2,1,1)

imshow(i)

subplot(2,1,2)

imshow(i2)
