The function header and comments are provided for you in the file called zones$\_$starter.m$.$ Don't forget to remove from the Testing your zones function

To test your zones function, first read the dome picture into MATLAB by typing this into the Command Window:

img $=$ imread$(\text{'}$dome$\_$area.jpg$\text{'})$;

Then get a set of radiation data:

rad $=$ scan$\_$radiation$(30)$;

Next, call your

function and save the smoothed data back into rad:

rad $=$ removeNoise$($rad$,15)$;

Finally, call zones and show the result as an image:

imshow$($zones$($img$,$ rad$))$;

If your removeNoise function and

functions are working correctly, you should see a picture that looks like this:

filename before you try to call this function.

function $[$ img $]=$ zones$($ img, rad $)$

$\%$ Generates an image colored according to radiation

$\%$ threat zones. Values from rad are used to determine

$\%$ the zone, and the hue value in img is set accordingly.

$\%$

img: a $3-$dimensional matrix of numbers representing

an image in RGB $($red$-$green$-$blue$)$ format, which

forms the background to which the heatmap

colors are applied.

rad: a matrix of numbers representing the radiation

measurements, between $0$ and $100$ millisieverts.

It has the same width and height as the img parameter.
