1. Image processing using matlab
BY, ROHIT SINHA (1SI11TE038)
ORIGINALIMAGE
I=imread('E:rohitdocrohit.jpg');
imshow(I);
RESIZED IMAGE
r=imresize(I,0.5);
imshow(r);

2. NEGATIVEIMAGE
r2=imcomplement(I);
figure,imshow(r2);

3. ROTATED IMAGE
r2=imcomplement(I);
figure,imshow(r2);
theta=30;
r3=imrotate(I,theta);
figure,imshow(r3)

4. CROPED IMAGE
r4=imcrop(I,[6040 80 90]);
figure,imshow(r4)

5. CONVERTA GRAY LEVEL IMAGE TO BINARYIMAGE
r5=im2bw(I);
figure,imshow(r5)
CONVERTA TRUE COLOR IMAGE TO AN INDEXEDIMAGE
r6=rgb2ind(I,0.1);
figure,imshow(r6)

6. CONVERTA GRAY SCALEIMAGE TO AN INDEXED IMAGE
r7=grayslice(I,50);
figure,imshow(r7)

7. NOISEDINTERRUPTED IMAGE
r8=imnoise(I,'salt&pepper',0.22);
figure,imshow(r8)
ADJUST THE IMAGE
r9=imadjust(I,[00.2],[0.51]);
figure,imshow(r9)
