$4.$ Does the visual appearance of the denoised image improve with averaging more

realizations$/$images$?$ How does your answer compare with the MSE for each case? $(2$ points$)$

$5.$ Comment on your assessment of denoising by temporal averaging with denoising by spatial

filtering? The assessment criteria should include MSE and visual appearance $($image looks blurry,

dim and so forth$).(3$ points$)$
