Function Documentation

copy_and_scale_uchar()

rslf::Mat rslf::copy_and_scale_uchar

(

Mat

img

)

Build a copy of the matrix scaled to uchar (0..255).

Parameters

img	The matrix to be scaled.

Returns

A copy of the matrix, scaled to uchar.

draw_red_lines()

rslf::Mat rslf::draw_red_lines	(	Mat	img,
		int	fill_row_red = -1,
		int	max_height = -1,
		int	fill_col_red = -1,
		int	max_width = -1
	)

Scale values to plottable (uchar 0..255) and overlays the given matrix with red lines.

Parameters

img	The matrix to be plotted.
fill_row	Fill a row in blank? -1 for no, else row index
max_height	Truncate the image to this height.
fill_col	Fill a col in blank? -1 for no, else col index
max_width	Truncate the image to this width.

plot_mat()

void rslf::plot_mat	(	Mat	img,
		std::string	window_name = "Image"
	)

Plot the provided cv::Mat in a cv::namedWindow.

Parameters

img	The matrix to be plotted.
window_name	Name of the created window.
