在Alpha pose中使用了poseflow进行pose tracking,而poseflow中在匹配的过程中使用了deep matching进行匹配。deep matching原本在fedora下配置,在Ubuntu下安装时会遇到各种问题,下面介绍其在Ubuntu下的编译安装方法。
一:DeepMatching
DeepMatching主页:http://lear.inrialpes.fr/src/deepmatching/
下载安装了其中的CPU版本:
Version 1.2.2
1. 下载压缩包:
deepmatching_1.2.2.zip
2. 解压开后
make clean all
一直出现错误:(这里错误是deepmatching文件夹下的makefile引起的)
下面是具体错误,最终可以使用的makefile版本往下拖拖拖。。。
g++: error: /usr/local/atlas/lib/libsatlas.so: No such file or directory
make: *** [deepmatching] Error 1
所以,借鉴大家的智慧:

#先装库:(一般都装过)
sudo apt-get install libatlas_dev#我找不到libatlas_dev文件 可以安装libatlas-dev
sudo apt-get install libatlas_base_dev
#然后查找libcblas.a等的路径,转到路径/usr/lib下:
sudo ld -shared -o libsatlas.so --whole-archive libatlas.a liblapack.a --no-whole-archive libf77blas.a libcblas.a
#修改 makefile 文件:
LAPACKLDFLAGS=/usr/lib64/atlas/libsatlas.so
改为LAPACKLDFLAGS=/usr/lib/libsatlas.so
#修改第24行,改为静态编译
all: deepmatching 改为 all: deepmatching-static
并修改以下静态链接的地址,我的地址如下,请确保安装了所有的库,并且路径正确,特别是libgfortran.a,libquadmath.a的路径在gcc下面,务必找到对应的文件以及其位置
改为:
STATICLAPACKLDFLAGS=-fPIC -Wall -g -fopenmp -static -static-libstdc++ /usr/lib/x86_64-linux-gnu/libjpeg.a /usr/lib/x86_64-linux-gnu/libpng.a /usr/lib/x86_64-linux-gnu/libz.a /usr/lib/libblas.a /usr/lib/gcc/x86_64-linux-gnu/4.8/libgfortran.a /usr/lib/gcc/x86_64-linux-gnu/4.8/libquadmath.a
CC=g++
OS_NAME=$(shell uname -s)
ifeq ($(OS_NAME),Linux)
LAPACKLDFLAGS=/usr/lib/libsatlas.so # single-threaded blas
#LAPACKLDFLAGS=/usr/lib64/atlas/libtatlas.so # multi-threaded blas
#BLAS_THREADING=-D MULTITHREADED_BLAS # remove this if wrong
endif
ifeq ($(OS_NAME),Darwin) # Mac OS X
LAPACKLDFLAGS=-framework Accelerate # for OS X
endif
LAPACKCFLAGS=-Dinteger=int $(BLAS_THREADING)
STATICLAPACKLDFLAGS=-fPIC -Wall -g -fopenmp -static -static-libstdc++ /usr/lib/x86_64-linux-gnu/libjpeg.a /usr/lib/x86_64-linux-gnu/libpng.a /usr/lib/x86_64-linux-gnu/libz.a /usr/lib/libblas.a /usr/lib/gcc/x86_64-linux-gnu/4.8/libgfortran.a /usr/lib/gcc/x86_64-linux-gnu/4.8/libquadmath.a # statically linked version
CFLAGS= -fPIC -Wall -g -std=c++11 $(LAPACKCFLAGS) -fopenmp -DUSE_OPENMP -O3
LDFLAGS=-fPIC -Wall -g -ljpeg -lpng -fopenmp
CPYTHONFLAGS=-I/usr/include/python2.7
LIBFLAGS= -L/lib/x86_64-linux-gnu -lpng -ljpeg -lz -lblas
SOURCES := $(shell find . -name '*.cpp' ! -name 'deepmatching_matlab.cpp')
OBJ := $(SOURCES:%.cpp=%.o)
HEADERS := $(shell find . -name '*.h')
all: deepmatching-static
.cpp.o: %.cpp %.h
$(CC) -o $@ $(CFLAGS) -c $+
deepmatching: $(HEADERS) $(OBJ)
$(CC) -o $@ $^ $(LDFLAGS) $(LAPACKLDFLAGS)

g++ $(CFLAGS) -c deepmatching_wrap.c $(CPYTHONFLAGS)
g++ -shared $(LDFLAGS) $(LAPACKLDFLAGS) deepmatching_wrap.o $(OBJ) -o _deepmatching.so $(LIBFLAGS)
clean:
rm -f $(OBJ) deepmatching *~ *.pyc .gdb_history deepmatching_wrap.o _deepmatching.so deepmatching.mex???
1.此时可以愉快的在/deepmatching下
make clean all
make python
python
import deepmatching
2.matlab有libsatlas.so的各种问题,最后使用的python版本的
按照README(在deepmatching下)
make python
import deepmatching as dm
dm.deepmatching() # show some help about options
from PIL import Image
import numpy as np
img1 = np.array(Image.open('liberty1.png'))
img2 = np.array(Image.open('liberty2.png'))
matches = dm.deepmatching( img1, img2, '-downscale 2 -v' )
遇到了一点小问题,把原本deepmatching.py中116行
# if None in (im1,im2):
# usage_python()
# return
改为:
if im1 is None or im2 is None:
usage_python()
return
