HessianLaplace blob detector.
Hello, I want to try to implement HessianLaplace blob detector (as mentioned in requested features on github page). Can someone give me the list of corresponding papers, using which I can implement it. Thank you.
Now I have a more wellformed question: Do you think it is also feasible to approximate laplacian of gaussian with haar wavelets? понедельник, 2 марта 2015 г., 18:05:09 UTC+1 пользователь Daniil Pakhomov написал:

Hello Daniil Unfortunately, I am not that wellinformed to comment about haar wavelets, I will definitely read up though. Constructing 2 image cubes is not required, you will construct one to determine (x,y) coordinates of maximas using the the determinant of hessian image cube. Once that is done, for only those (x, y) points you will compute Laplacian Of Gaussian for different scales, and final the scale space maxima for only those points. This gives us the best of both approaches. Thanks Vighnesh On Thursday, March 5, 2015 at 4:07:59 AM UTC+5:30, Daniil Pakhomov wrote:

Great! Thank you. What I am thinking about is to take your _hessian_matrix_det() and make it also return d_xx + d_yy for each element. So, on the output I will get determinant of Hessian and also a Laplacian. I have a small question: d_xx + d_yy will be a scale normalized Laplacian in your notation? понедельник, 2 марта 2015 г., 18:05:09 UTC+1 пользователь Daniil Pakhomov написал:

Really sorry for spamming you with questions. No more need to answer. I implemented this detector and it works as fast as your determinant of Hessian approach implementation. It passes all you tests and works better with coin() images (it doesn't detect a false coin as determinant of Hessian does in the example). May I ask you to do a review of my code later? Thank you. понедельник, 2 марта 2015 г., 18:05:09 UTC+1 пользователь Daniil Pakhomov написал:

We'd welcome this as a PR on GitHub. That would be the ideal place for code review, etc. On Sunday, March 8, 2015 at 4:01:12 PM UTC5, Daniil Pakhomov wrote:

Thanks. I've sent it. 20150309 1:39 GMT+01:00 Josh Warner <silvertrumpet999@gmail.com>:
