Functions
Clears the algorithm state
Positional Arguments
- self:
Evision.AlignExposures.t()
Python prototype (for reference only):
clear() -> None
Returns true if the Algorithm is empty (e.g. in the very beginning or after unsuccessful read
Positional Arguments
- self:
Evision.AlignExposures.t()
Return
- retval:
bool
Python prototype (for reference only):
empty() -> retval
getDefaultName
Positional Arguments
- self:
Evision.AlignExposures.t()
Return
- retval:
String
Returns the algorithm string identifier. This string is used as top level xml/yml node tag when the object is saved to a file or string.
Python prototype (for reference only):
getDefaultName() -> retval
@spec process( t(), [Evision.Mat.maybe_mat_in()], [Evision.Mat.maybe_mat_in()], Evision.Mat.maybe_mat_in(), Evision.Mat.maybe_mat_in() ) :: t() | {:error, String.t()}
Aligns images
Positional Arguments
self:
Evision.AlignExposures.t()
src:
[Evision.Mat]
.vector of input images
dst:
[Evision.Mat]
.vector of aligned images
times:
Evision.Mat.t()
.vector of exposure time values for each image
response:
Evision.Mat.t()
.256x1 matrix with inverse camera response function for each pixel value, it should have the same number of channels as images.
Python prototype (for reference only):
process(src, dst, times, response) -> None
@spec read(t(), Evision.FileNode.t()) :: t() | {:error, String.t()}
Reads algorithm parameters from a file storage
Positional Arguments
- self:
Evision.AlignExposures.t()
- fn_:
Evision.FileNode.t()
Python prototype (for reference only):
read(fn_) -> None
save
Positional Arguments
- self:
Evision.AlignExposures.t()
- filename:
String
Saves the algorithm to a file. In order to make this method work, the derived class must implement Algorithm::write(FileStorage& fs).
Python prototype (for reference only):
save(filename) -> None
@spec write(t(), Evision.FileStorage.t()) :: t() | {:error, String.t()}
Stores algorithm parameters in a file storage
Positional Arguments
- self:
Evision.AlignExposures.t()
- fs:
Evision.FileStorage.t()
Python prototype (for reference only):
write(fs) -> None
@spec write(t(), Evision.FileStorage.t(), binary()) :: t() | {:error, String.t()}
write
Positional Arguments
- self:
Evision.AlignExposures.t()
- fs:
Evision.FileStorage.t()
- name:
String
Has overloading in C++
Python prototype (for reference only):
write(fs, name) -> None
