libccv

Welcome to the ccv wiki!

Intro

This is a modified version of libccv which can be compiled with dietlibc-0.29.

In current version, only bbfdetect is comfirmed working correctly.

This version is forked from the unstable branch of ccv.

Compile

1. // get the code
   $ cd ~/research
   $ git clone git://github.com/patriot7/ccv.git

2. // build the library
   $ cd ./ccv/lib
   // as the configuration has been included in the modified version, we can skip the config step
   $ make

3. // now we only have bbfdetect works so we just need to build
   $ cd ../bin
   $ make bbfdetect

Run

1. // run the progarm ./bbfdetect ../samples/face | ./bbfdraw.rb output.png

   // as libpng and libjpeg was not compiled in the lib, now we can only process BMP files, for example, we have included an example photo.bmp in bin/

   $./bbfdetect.bin ./photo.bmp ../samples/face | ./bbfdraw.rb ./photo.bmp output.png

   // the ruby script will circle out the faces in the output.png

** A result of test cases can be found in resluts**

• commentted the complex.h in lib/ccv_numeric.c
• have two global variables in ccv_memory.c "not _thread"
• the path to diet program need to be manually changed in config.mk
• casted several math functions. more details could be found in lib/ccv_math.h
