In question 2, section 2, the original and reconstructed images aren't in the same size. How do I compare them? | |
|
Indeed the images aren't the same, due to the operation of impyramid. This section remained from the original question 2, where you had to implement the pyramid yourselves. You have two options: The easy one: Resize the original image to the size of the reconstructed one, and show that the error is small. It will not be zero. The longer one: Implement the 'expand' operator yourselves using the filter we learned in the tutorial. Do all the expansions with your operator, and show that the error is zero. Note that in the longer one, the filter must have a gain factor of 4 to compensate for the upsampling. Both ways will get all points if done correctly. |
In question 1, section 7, what value from the graph do I need to take as the radius? | |
| You should take the value of sigma at the maximum point, and multiply it by sqrt(2). |
