11. Write a Python function to check whether a number is perfect or not. Go to the editor According to Wikipedia : In number theory, a perfect number is a positive integer that is equal to the sum of its proper positive divisors, that is, the sum of its positive divisors excluding the number itself (also known as its aliquot sum). Equivalently, a perfect number is a number that is half the sum of all of its positive divisors (including itself). Example : The first perfect number is 6, because 1, 2, and 3 are its proper positive divisors, and + 2 + 3 = 6. Equivalently, the number 6 is equal to half the sum of all its positive divisors: (1 + 2 3 + 6 )/2 = 6. The next perfect number is 28 = 1 + 2 + 4 + 7 + 14. This is followed by the perfect numborc 106 ond 8128

I need the answer as soon as possible
Please help me, what should I add to this code for me to be able to resize the each of the images into the size that I want. Our language is Python.
Please answer the question in the image with reason/detail. Thank you
For the following 2 images, both have 8x8 size with black and white pixels. Although they look quite different, their histograms are identical. Suppose that both images are blurred with a 3x3 smoothing masks with zeros edge extension, would the new histograms still be the same? Explain your answer. 2.
But I want the output like the images below. I want all the circles are right in the middle of each small square.
Why do we talk about the output's visual quality being reduced when rasterizing?
How does one acquire ‘stable’ images from the subcostal window
Give details of the convolution operation and describe its application in the field of image processing. You should support your answer with the use of mathematical expressions, pseudo- code and diagrams.
