在windows下运行DPM 较早版本的DPM已经有人配置好了windows下的编译环境 项目代码见： https://github.com/j0x7c4/dpm （测试可用） https://github.com/luckykelfor/DPM4.01_windows

注意先mex -setup 选可用的编译器

>> compile

  1. 从官网下载最新版本的DPM Discriminatively trained deformable part models
  2. 解压，查看README文件 Basic Usage
Basic Usage

===========

 

1. Unpack the code.

2. Start matlab.

3. Run the 'compile' function to compile the helper functions.

   (you may need to edit compile.m to use a different convolution 

    routine depending on your system)

4. Load a model and an image.

5. Use 'process' to detect objects.
  1. 也就是说配置好matlab的mex工具后，运行compile即可。之后就可以运行demo了

注意在ubuntu 14.04中，默认的gcc版本为4.8，而MATLAB2014a/2014b仅支持4.7.x 所以出错

Error using mex

No supported compiler or SDK was found. For options, visit 

http://www.mathworks.com/support/compilers/R2014a/glnxa64.

卸载gcc，安装gcc-4.7后，matlab不识别gcc-4.7，需要修改mex配置：

Ubuntu 14.04 by default has the compiler GCC 4.8, but Matlab R2014b .mex files require GCC 4.7.x

Error: You are using gcc version '4.8.2'. The version of gcc is not supported.

Solution:

Install GCC 4.7 and G++ 4.7
sudo apt-get install gcc-4.7 g++-4.7

Copy the mex-options file and provide read permissions
cp /usr/local/MATLAB/R2014b/bin/mexopts.sh ~/.matlab/R2014b/mexopts.sh

Make edits
sudo vim ~/.matlab/R2014b/mexopts.sh

Change
CC=’gcc’ to CC=’gcc-4.7′
CCX=’g++’ to CCX=’g++-4.7′
