Detailed Description

Pseudo-vector (abstract) for use with two-dimensional objects, like images. Provide a two-dimensional array's rows and columns as vectors with array addressing.

Member Function Documentation

virtual coeff ImageVector::at

(

int

pos

)

[pure virtual]

Return a value (abstract). The value is taken from the vector's position {pos}.

Parameters:

pos	the position

Returns:

the value at that position

Implements ReferenceVector.

Implemented in FullVector, ColumnVector, and RowVector.

virtual void ImageVector::go

(

int

root

)

[virtual]

Set new root. Depending of what concrete instance is the current row or col will be set.

Exceptions:

invalid_argument

a negative value was given for the new root

Parameters:

root	the new root

Implements ReferenceVector.

Reimplemented in FullVector, ColumnVector, and RowVector.

virtual bool ImageVector::sanity

(

void

)

[virtual]

Checks integrity. If the array's dimensions have been changed (resize operation) {false} will be returned.

Implements ReferenceVector.

virtual int ImageVector::size

(

void

)

[pure virtual]

Return the vector's size (abstract). Depending on the concrete instance we will get the associated array's number of rows or cols.

Returns:

the vector's size

Implements ReferenceVector.

Implemented in FullVector, ColumnVector, and RowVector.

virtual void ImageVector::to	(	int	pos,
		coeff	val
	)		[pure virtual]

Assign a value (abstract). A new value {val} is assigned to the vector's position {pos}.

Parameters:

pos	the position
val	the new value

Implements ReferenceVector.

Implemented in FullVector, ColumnVector, and RowVector.

virtual void ImageVector::update

(

void

)

[virtual]

Updates the vector's settings. This is necessary each time after the array has been resized.

Implements ReferenceVector.

Reimplemented in ColumnVector, FullVector, and RowVector.

coeff ImageVector::weight

(

void

)

Return the sum of the vector's absolute values

Returns:

the sum of the vector's absolute values
