I have written the below code for image enhacement . p is the enhanced image now how to display the enhanced image.

a=imread('E:\ite dinner party\IMG_1056.JPG');

imshow(a)

b=rgb2gray(a);

figure,imshow(b);

c=b(:);

lem=225;

minim=min(c(:));

maxim=max(c(:));

[m,n]=size(b);

x=zeros(1,225);

q=zeros(1,225);

w=zeros(1,225);

r=zeros(1,225);

E=zeros(1,225);

u=zeros(1,225);

for i=1:m

for j=1:n

g=b(i,j);

x(i,j)=((g-minim)/(maxim-minim));

q(i,j)=((1+lem)*x(i,j))/(1+lem*x(i,j));

w(i,j)=(1-x(i,j))/(1+(3*lem*x(i,j))+(lem^2*x(i,j))+x(i,j));

r(i,j)=1-q(i,j)-w(i,j);

E(i,j)=(1/x(i,j))*(sum(sum(r(i,j)*exp(1-r(i,j)))));

u(i,j)=maxim*(E(i,j)+lem);

t=q(i,j)^1.25;

y=1-t;

for y=0:0.1:1

if y<=0.5

p=2*(y^2);

else

p=1-2*((1-y)^2);

end

end

end

end
