The wavelet transform of a one dimensional signal is an image. <EM>Num_Trans</EM> is the wavelet transform chosen. 6 transforms are possible: <DL COMPACT> <DT>1. <DD>French hat <DT>2. <DD>Mexican hat <DT>3. <DD><EM>à trous</EM> algorithm with a linear scaling function <DT>4. <DD><EM>à trous</EM> algorithm with a B1-spline scaling function <DT>5. <DD><EM>à trous</EM> algorithm with a B3-spline scaling function <DT>6. <DD>Morlet's transform. </DL>in case of Morlet's transform, the wavelet transform is complex. The modulus of the transform is stored in the first part of the output image, and the phase in the second part. Default value is 2. <EM>Num_Line</EM> is the line number in the input image which will be used (1 is the default value). <EM>Channel</EM> is the number of channels per octave (the default value is 12). This parameter is not used in the <EM>à-trous</EM> algorithm because <EM>à-trous</EM> algorithm is a diadic algorithm (1 channel per octave). <EM>Nu</EM> is the Morlet's parameter and is only used with Morlet's transform. <P> <HR> <!--Navigation Panel--> <A NAME="tex2html6035" HREF="node369.html"> <IMG WIDTH="37" HEIGHT="24" ALIGN="BOTTOM" BORDER="0" ALT="next" SRC="icons.gif/next_motif.gif"></A> <A NAME="tex2html6032" HREF="node346.html"> <IMG WIDTH="26" HEIGHT="24" ALIGN="BOTTOM" BORDER="0" ALT="up" SRC="icons.gif/up_motif.gif"></A> <A NAME="tex2html6026" HREF="node367.html"> <IMG WIDTH="63" HEIGHT="24" ALIGN="BOTTOM" BORDER="0" ALT="previous" SRC="icons.gif/previous_motif.gif"></A> <A NAME="tex2html6034" HREF="node1.html"> <IMG WIDTH="65" HEIGHT="24" ALIGN="BOTTOM" BORDER="0" ALT="contents" SRC="icons.gif/contents_motif.gif"></A> <BR> <B> Next:</B> <A NAME="tex2html6036" HREF="node369.html">REC1D/WAVE</A> <B> Up:</B> <A NAME="tex2html6033" HREF="node346.html">Commands Description</A> <B> Previous:</B> <A NAME="tex2html6027" HREF="node367.html">TUTORIAL/WAVE</A> <!--End of Navigation Panel--> <ADDRESS> <I>Petra Nass</I> <BR><I>1999-06-15</I> </ADDRESS> </BODY> </HTML>
