Hi, everybody ! I have got one question, concerning the Brisk method work. I have found key points on my image ( see: ) and then I wanna increase the "Size"(diameter) of each key point. I have changed key point "Size" field, but it didn't help ( actually, size of key point in the program was changed successful, but visually it didn't change). Tell me please, maybe there is another way to increase the "Size"(diameter) of keypoint ? Thanks/

  • please put your img here, not on an external bin (where it will expire)

  • please explain, why you need to change this ?

  • " I have changed key point "Size" field" -- well, after the detection ? that does not make any sense.

what about using this constructor overload, which allows to set the radii ?
