Opencv mat multiply scalar. How to estimate orientation and coherency of an anisotropic image by a gradient structure tensor. I am using opencv 2 4 6 library with vs 2010. A alpha per element multiplication and division. Periodic noise removing filter goal.

The same can be done with the division operation. This is a list of implemented matrix operations that can be combined in arbitrary complex expressions here a b stand for matrices mat s for a scalar scalar alpha for a real valued scalar double. In addition they can be converted to from cvscalar. Again both operations can be performed with a matrix and a scalar.

Motion deblur filter next tutorial. Active 6 years 7 months ago. So how can i do that using. Multiplication can be done using opencv s multiply function similar to the mat mul function while division can be performed using the divide function.

Now i want to multiply 1 5 with cv gpumat. Add const matexpr expr1 const scalar s matexpr res const virtual void assign const matexpr expr mat m int type 1 const 0 virtual void augassignadd const matexpr expr mat m const virtual void augassignand const matexpr expr mat m const virtual void augassigndivide const matexpr expr mat m const virtual void. If you are familiar with the c interface pre version 2 1 implementation of the opencv library you will remember the data types iplimage and cvmat you might also recall cvarr in the c implementation these are all gone replaced with cv mat this means no more dubious casting of void pointers in function arguments and in general is a tremendous enhancement in the internal. Here are some examples.

I compiled o cuda 4 2 9 on mypencv this library with laptop and it works fine. Viewed 15k times 1. Being derived from vec tp 4 scalar and scalar can be used just as typical 4 element vectors. The type scalar is widely used in opencv to pass pixel values.

Ask question asked 10 years 3 months ago. What the gradient structure tensor is. Class cv scalar tp template class for a 4 element vector derived from vec. Most of the existing function allows only matrix matrix and matrix scalar operations.

I am trying to find the easiest way to add subtract a scalar value with a opencv 2 0 cv mat class.
