行人检测 DPM 方法 (Oct 30 2015)
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

文件 Basic UsageBasic 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.
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′
