Gray Level Slicing: High-light specific range of gray
values without background and with background.
Read kidney.tif file. Enter lower and
upper threshold value from the user. Apply gray level slicing with and without
background. Display the result.
CODE:
clc; clear all;
i=imread('kidney.tif'); % should be graylevel image
j=double(i);
k=double(i);
[row,col]=size(j);
T1=input('Enter the Lowest threshold value:');
T2=input('Enter the Highest threshold value:');
for x=1:row
for y=1:col
if((j(x,y)>T1) && (j(x,y)<T2))
j(x,y)=i(x,y);
k(x,y)=255;
else
j(x,y)=0;
k(x,y)=0;
end
end
end
subplot(311), imshow(i), title('Original image')
subplot(312), imshow(uint8(j)), title('Graylevel slicing with background')
subplot(313), imshow(uint8(k)), title('Graylevel slicing without background')
OUTPUT RESULT:
