owtrans_fimage

$ \bigcirc$Name


owtrans_fimage Generates a fimage for visualization of orthonormal wavelet decomposition




$ \bigcirc$Command Synopsis


owtrans_fimage [-r RecursNum] [-c Contrast] WavTrans VisuImage



-r RecursNum : Number of levels of wavelet transform (default 1)

-c Contrast : Multiplicative facor for wavelet coefficients

WavTrans : Input wavelet transform

VisuImage : Visualization image




$ \bigcirc$Function Summary


void owtrans_fimage (Wtrans , Output , NumRec , Contrast )

Wtrans2d Wtrans ;

Fimage Output ;

int *NumRec ;

double *Contrast ;




$ \bigcirc$Description


owtrans_fimage creates a file of type Fimage for the visualization of a wavelet decomposition (see owave2 module's documentation). The sub-images are displayed in the following telescopic way. The visualization image is divided in four identical rectangles. The details D11, D12, and D13 are respectively in the upper right, lower left, and lower right corners of the visualization image. The sub-images corresponding to coarser scales are displayed in the upper left rectangle. The organization in this rectangle is the same as for the level one : the details D21, D22, and D23 are respectively in the upper right, lower left, and lower right corners, a.s.o.. At the coarsest level, the average sub-image is displayed in the upper left corner.

The prefix names of the files containing the wavelet decomposition's sub-image is WavTrans, and their syntax must obey the rules described in owave1 module's documentation. The visualization image is stored in the file VisuImage.

The -r option specifies the number of level in the decomposition (default : 1).

The -c oprion specifies the multiplicative constant by which the detail coefficients are multiplied (default : 1.0).
