## README

# Hessian_sift
Hessian-Affine detector, SIFT descriptor  
original from : [hesaff](https://github.com/perdoch/hesaff)


## 编译特征提取接口
Makefile(linux, opencv3.2)
```
all: *.cpp
	g++ -O3 -Wall -o hesaff pyramid.cpp affine.cpp siftdesc.cpp helpers.cpp hesaff.cpp `pkg-config opencv --cflags --libs` -lrt

```
Makefile(mac, opencv4.1)
```
all: *.cpp
	g++ -std=c++11 -O3 -Wall -o hesaff pyramid.cpp affine.cpp siftdesc.cpp helpers.cpp hesaff.cpp `pkg-config opencv4 --cflags --libs`
```

## python测试
简单实验了原始sift和hesaff（图像宽最大限制500）
```
python demo_python.py
```
