plot_samples: Plot samples from denseness_sample

In bwimage: Describe Image Patterns in Natural Structures

Description

Plot samples from denseness_sample.

Usage

plot_samples(imagematrix, central_lines, central_collumns, width_size,
  height_size, sample_width, sample_height, sample_shape)

Arguments

imagematrix	The matrix to be analysed.
central_lines	Lines data (i.e. "Matrix(line)") provided by denseness_sample
central_collumns	Collumns data (i.e. "Matrix(column)") provided by denseness_sample
width_size	Real size of image width (in mm, cm, m, etc..).
height_size	Real size of image height (in mm, cm, m, etc..).
sample_width	Width of sample area.
sample_height	Height of sample area.
sample_shape	Inform the shape of sample unity used ("rectangle" or "ellipse"). See denseness_sample function.

Value

Plot of the analysed matrix (black and white) and sample locations (red).
