1. For this question, please see Question 1 in the iPython notebook (.ipynb file) provided alongside. Complete your implementation under the “YOUR CODE STARTS HERE” segment therein. Which of the following options correctly provides the standard deviation of row-wise means and the row-wise means themselves?
Options:
a) 1.23, [3.875, 8.375, 13.575]
b) 3.45, [3.375, 8.875, 13.375]
c) 4.08, [3.375, 8.375, 13.375]
d) 4.24, [3.875, 8.875, 13.875]
Answer: c) 4.08, [3.375, 8.375, 13.375]
Explanation: After computing row-wise means and then calculating their standard deviation, the result matches option C with standard deviation ≈ 4.08 and row-wise means as listed.
2. For this question, please see Question 2 in the iPython notebook (.ipynb file) provided alongside. Complete your implementation under the “YOUR CODE STARTS HERE” segment therein. Which of the following pairs represents the largest eigenvalue and its corresponding eigenvector?
Answer: c
Explanation: The implementation of eigenvalue decomposition shows that the largest eigenvalue and the correct corresponding eigenvector pair match option C.
3. For this question, please see Question 3 in the iPython notebook (.ipynb file) provided alongside. Complete your implementation under the “YOUR CODE STARTS HERE” segment therein. Which of the following is the sum of the elements in the modified list obtained after applying the function?
Options:
a) 1.03
b) 1.00
c) 1.50
d) 3.02
Answer: a) 1.03
Explanation: The provided function modifies the list by a set rule. After applying the function and summing the result, the correct total is 1.03.
4. For this question, please see Question 4 in the iPython notebook (.ipynb file) provided alongside. Complete your implementation under the “YOUR CODE STARTS HERE” segment therein. Now, which of the following is the GBR representation of the RGB image ‘golden retriever.jpg’ in programming question 1?
Answer: b
Explanation: The conversion from RGB to GBR involves swapping channels accordingly. After the transformation, the output matches option B.
5. For this question, please see Question 5 in the iPython notebook (.ipynb file) provided alongside. Complete your implementation under the “YOUR CODE STARTS HERE” segments therein. The shape of the ‘human mitosis’ image after applying a 5 × 5 mean filter is:
Options:
a) (512, 512)
b) (510, 510)
c) (508, 508)
d) (507, 507)
Answer: c) (508, 508)
Explanation: The convolution with a 5×5 kernel reduces the image dimensions by 4 in both directions (2 pixels per edge), resulting in (508, 508).
6. For this question, please see Question 6 in the iPython notebook (.ipynb file) provided alongside. Complete your implementation under the “YOUR CODE STARTS HERE” segments therein. The median value of the ‘human mitosis’ image before and after applying the 5 × 5 mean filter is _____ and ______ respectively.
6._____________
Answer: 10
Explanation: The median of the raw grayscale values is computed before applying the filter and found to be 10.
7______________________
Answer: 10.28
Explanation: The 5×5 mean filter smoothens the image, changing pixel intensity values and thus shifting the median to 10.28.
