Download image file, cottoncandy.TIF from the Google drive. This is how cotton candy looks like under SEM at large magnification. Write a program to do the following with this image.

Read and resize the image to half its original size. The resize function is in skimage.transform module.

Use a Gaussian filter with a sigma greater than 2 to filter the image. The image should become blurry because high frequency changes are filtered out.

Use the same filter again to filter the filtered image produced in b

Compare the two images produced in steps b and c. Notice that repeated filtering with a smoothing filter makes the image progressively blurrier.
