Please add these code into my code. $$Can I get the face detection code that can join with my code. I added the picture of my code.

Please don't copy from other post.cuz this is my second time posting. The answer from first time is not working.

I want to do face detection by using keystrokes

$($i$.$e$.1,2,3,4$etc$.)$and replace the detected face image

with:

a$.$A greyscale image

b$.$A blurred image $$adjust blurring so your face is not recognisable

c$.$A colour converted image $$reuse code from task $9$

d$.$A pixelate image. To perform pixelation use the following approach

i$.$Run step a $$so that your image is greyscale

ii$.$Split the detected face image into $5$x$5$pixel blocks

iii. Calculate the average pixel intensity of each block using image.get$($x$,$

y$)$; or use the pixel array $($to access each pixel$$s intensity$)$

iv$.$Paint the entire block using the average pixel intensity. Utilise this

command: outimage.set$($x$,$y$,$avePixInt$)$; or use the pixel array

v$.$Loop through all blocks repeating steps iii and iv in the lowest row again.

I can only post $5$ photos that's why i add first page code in below.

let video;

let snapshot;

let sliderRed;

let sliderGreen;

let sliderBlue;

function setup$()\{$

let canvas $=$ createCanvas$(800,500)$; $//$ Create a canvas for the grid

canvas.parent$(\text{'}$canvas$-$container'$)$; $//$ Append to the HTML container

video $=$ createCapture$($VIDEO$)$; $//$ Capture webcam feed

video.size$(160,120)$; $//$ Set the webcam feed resolution to $160$x$120$

video.hide$()$; $//$ Hide the live video feed $($we$\text{'}$ll display snapshots instead$)$

let snapshotButton $=$ select$(\text{'}$#snapshotbutton'$)$; $//$ Capture snapshot on button press

snapshotButton.mousePressed$($takeSnapshot$)$;

snapshotButton.position$(360,30)$;

sliderRed $=$ createSlider$(0,255,128)$;

sliderRed.position$(10,370)$; $//$ Position of the Red slider

sliderGreen $=$ createSlider$(0,255,128)$;

sliderGreen.position$(170,370)$; $//$ Position of the Green slider

sliderBlue $=$ createSlider$(0,255,128)$;

sliderBlue.position$(340,370)$; $//$ Position of the Blue slider
