* \file fhmtauto.c
|
||
|
* <pre>
|
||
|
*
|
||
|
* Main function calls:
|
||
|
* l_int32 fhmtautogen()
|
||
|
* l_int32 fhmtautogen1()
|
||
|
* l_int32 fhmtautogen2()
|
||
|
*
|
||
|
* Static helpers:
|
||
|
* static SARRAY *sarrayMakeWplsCode()
|
||
|
* static SARRAY *sarrayMakeInnerLoopDWACode()
|
||
|
* static char *makeBarrelshiftString()
|
||
|
*
|
||
|
* This automatically generates dwa code for the hit-miss transform.
|
||
|
* Here's a road map for how it all works.
|
||
|
*
|
||
|
* (1) You generate an array (a SELA) of hit-miss transform SELs.
|
||
|
* This can be done in several ways, including
|
||
|
* (a) calling the function selaAddHitMiss() for
|
||
|
* pre-compiled SELs
|
||
|
* (b) generating the SELA in code in line
|
||
|
* (c) reading in a SELA from file, using selaRead()
|
||
|
* or various other formats.
|
||
|
*
|
||
|
* (2) You call fhmtautogen1() and fhmtautogen2() on this SELA.
|
||
|
* This uses the text files hmttemplate1.txt and
|
||
|
* hmttemplate2.txt for building up the source code. See the file
|
||
|
* prog/fhmtautogen.c for an example of how this is done.
|
||
|
* The output is written to files named fhmtgen.*.c
|
||
|
* and fhmtgenlow.*.c, where "*" is an integer that you
|
||
|
* input to this function. That integer labels both
|
||
|
* the output files, as well as all the functions that
|
||
|
* are generated. That way, using different integers,
|
||
|
* you can invoke fhmtautogen() any number of times
|
||
|
* to get functions that all have different names so that
|
||
|
* they can be linked into one program.
|
||
|
*
|
||
|
* (3) You copy the generated source code back to your src
|
||
|
* directory for compilation. Put their names in the
|
||
|
* Makefile, regnerate the prototypes, and recompile
|
||
|
* the libraries. Look at the Makefile to see how I've
|
||
|
* included fhmtgen.1.c and fhmtgenlow.1.c. These files
|
||
|
* provide the high-level interfaces for the hmt, and
|
||
|
* the low-level interfaces to do the actual work.
|
||
|
*
|
||
|
* (4) In an application, you now use this interface. Again
|
||
|
* for the example files generated, using integer "1":
|
||
|
*
|
||
|
* PIX *pixHMTDwa_1(PIX *pixd, PIX *pixs, const char *selname);
|
||
|
*
|
||
|
* or
|
||
|
*
|
||
|
* PIX *pixFHMTGen_1(PIX *pixd, PIX *pixs, const char *selname);
|
||
|
*
|
||
|
* where the selname is one of the set that were defined
|
||
|
* as the name field of sels. This set is listed at the
|
||
|
* beginning of the file fhmtgen.1.c.
|
||
|
* As an example, see the file prog/fmtauto_reg.c, which
|
||
|
* verifies the correctness of the implementation by
|
||
|
* comparing the dwa result with that of full-image
|
||
|
* rasterops.

||
