reflectImageIndices()

template<typename realT >

std::vector<size_t> mx::improc::reflectImageIndices	(	const std::vector< size_t > &	idxi,
		int	w,
		int	h,
		realT	xc,
		realT	yc
	)

Reflect vector indices across the given center pixel.

This assumes column major order.

Returns

the vector of reflected indices

Parameters

[in]	idxi	the vector indices to reflect
[in]	w	the image width
[in]	h	the image height
[in]	xc	the image center x coordinate
[in]	yc	the image center y coordinate

rotateMask()

template<typename imageT , typename transformT = cubicConvolTransform<typename imageT::Scalar>>

void mx::improc::rotateMask	(	imageT &	rotMask,
		imageT &	mask,
		typename imageT::Scalar	angle
	)

Rotate a binary mask.

Sets edge pixels to 0 or 1 depending on the interpolation, being below/above 0.5.
