Split the image into two parts.

Split the image into two parts, right and left. Apply on the right part - The conversion of the logarithmic and the left exponential conversion. what's wrong with my code?

clc
clear
close all
%%Lets Start.
I = imread('2.jpg');
I = rgb2gray(I);
y = 15*log(1+double(I));
x = 1*(double(I).^1/100);
figure
imshow(uint8(y))
figure
imshow(double(x))
for i = 1:375
    for j = 1:500
        if (j<=250)
        I(i,j) = 15*log(1+double(I(i,j)));
        else
        I(i,j) = 1*(double(I).^1/100);
        end
    end
end
figure
imshow(I)
