Description

$1.$ Use Matlab to Capture an image from the webcam, Add gaussian noise to the captured image img using the command imnoise$($img$,$gaussian$)$; and Compute the luminance of the resultant image.

Then, you must write MATLAB functions using the image computed before performing the following

tasks:

$-$ A function receives an image and integer value and yields the image with luminance modified in value.

$-$ A function that receives an image and returns the invert of its values.

$-$ A function that receives an image and returns the log of the image.

$-$ A function that receives an image and a double value returns the image at the power of value.

$-$ A function that receives an image and two different integers returns an image whose values are the range of the two integers inserted.

$-$ A function that receives an image and an integer value. It returns a binary image with the threshold at value.

$-$ A function that receives two matrices and returns their convolution.

$-$ Use the function before to clean the image and detect borders.

Remember that the use of MATLAB$$s image$-$processing commands is forbidden! The command conv$2$ is also forbidden.
