Ex 3 Hessian threshold Q1 and Q4

Beitrag von Y2Kie »

Hi all,

regarding the hessian threshold, with thres= 300 I don't get the interest points in my implementation. But if the threshold decreases to approx. 30-50, I can find the interest points.
is the threshold value 300 (in Question 1)and 1e3 (in Question 4b) correct? or is that so that we should find the correct one?

thanks

As explained in the answer for the topic "Ex3 1a)", there is different possible implementations of the second derivative, and the threshold needs to be adapted accordingly.
It does not mean that your solution is not correct, it means that you computed the second derivative in a different way.
