| + | ===== Linear filters ===== | ||
| + | |||
| + | **Linear Filters** are filters described by [[http://en.wikipedia.org/wiki/Linear_map|linear operators]], i.e. operators which satisfy linearity requirements: | ||
| + | |||
| + | //F(x+y) = F(x) + F(y)// и //F(Const*x) = Const* F(x)//. | ||
| + | |||
| + | |||
| + | Besides [[http://en.wikipedia.org/wiki/Affine_transformation|Affine transformations]] there are three linear filters in the program: | ||
| + | * [[градиент|Gradient filter]] | ||
| + | * [[фильтр_лапласа|Laplace filter]] | ||
| + | * [[фильтр_гаусса|Gauss filter]] | ||
