Q) Can you please amend/change the following code in such a way that USER INPUTS THE COLOUR AND THAT COLOUR DETECTS THAT CERTAIN PART OF THE IMAGE.

NOTE : USE THE DIP techniques to solve the question , thankYOU.

% Demo macro to very, very simple color detection in RGB color space

clc;

close all;

% Read standard MATLAB demo image.

rgbImage = imread('4.jpg');

% Display the original image.

subplot(3, 4, 1);

imshow(rgbImage);

% Maximize figure.

set(gcf, 'Position', get(0, 'ScreenSize'));

% Split the original image into color bands.

greenBand = rgbImage(:,:, 2);

blueBand = rgbImage(:,:, 3);

% Threshold each color band.
