draw a minion carrying a ginger in matlab

main.m
% Read image of minion
minion = imread('minion.jpg');
% convert image to grayscale
bw_minion = rgb2gray(minion);
% make background pixels as white and minion pixels as black
bw_minion = imbinarize(bw_minion);
% invert image
bw_minion = ~bw_minion;

% the coordinates of the minion's arm
x1 = 240; y1 = 230;
x2 = 380; y2 = 190;

% create a line representing the arm of the minion that will carry the ginger
bw_minion = insertShape(bw_minion, 'Line', [x1,y1,x2,y2], 'LineWidth', 2, 'Color', 'black');

% read image of ginger
ginger = imread('ginger.jpg');

% resize ginger image to fit in minion's arm
ginger = imresize(ginger, [150,150]);
% convert image to grayscale
bw_ginger = rgb2gray(ginger);
% make background pixels as white and ginger pixels as black
bw_ginger = imbinarize(bw_ginger);
% invert image
bw_ginger = ~bw_ginger;

% calculate angle of the minion's arm
theta = atan2(y2-y1, x2-x1)*180/pi;

% rotate ginger image with the calculated angle
bw_ginger = imrotate(bw_ginger, theta, 'crop');

% get the size of the ginger image
[m, n] = size(bw_ginger);

% calculate coordinates where ginger image will be inserted
x = round(x2 - m/2); y = round(y2 - n/2);

% insert ginger image to the minion's arm
bw_minion(x:x+m-1, y:y+n-1) = bw_ginger;
% show final image
imshow(bw_minion);
