%% INPUTS
% x --> is a given low-illumination image
% Lambda -- > controls the amount of enhancement

%% OUTPUT
% out --> illumination-enhanced image


%% Starting implementation %%
clear all; clc; close all;
%% Input the image
x = im2double(imread('1.jpg'));
%% Run IBA
Lambda = 4;
tic; out = IBA(x, Lambda); toc;
%% Display the results
figure; imshow(x); title('Orignal')
figure; imshow(out); title('IBA-Enhanced')
%% Write the output as an image
% imwrite(out,'IBA_L4.jpg')
