Wimage.info.plot {fields} | R Documentation |

## Plot to check 2-d multiresolution indexing

### Description

Plots in image format the differnt blocks of coefficents associated
with a 2-d multiresolution. This function can be used to check the
Wtransform indexing
functions and is also an introduction to how the coefficients are
organized.

### Usage

Wimage.info.plot(m, n, cut.min)

### Arguments

`m` |
Number of rows in image |

`n` |
Number of columns of image |

`cut.min` |
Smallest number of smooth basis functions. Coarsest resolution will
have atleast cut.min X cut.min basis functions with support on a regular grid. |

### Details

This function was used to check the (compicated) indexing functions work.
But it also might a useful graphics to desribe how the different levels of wavelet
coefficients are pack into the image format.

### Examples

#
# 64X 128 image coarsest level has 8X16 smooth basis funcitons.
#
# NOTE as a matrix the image plot is upside down! Rows are along X-axis and
# columns on Y
# e.g. the (1,1) element is the lower left corner.
