matlab配置vlfeat库(v0.9.18)

VLFeat -Vision Lab Features Library

GitHub - vlfeat/vlfeat: An open library of computer vision algorithms https://github.com/vlfeat/vlfeat

VLFeat的主页:http://www.vlfeat.org/index.html

VLFeat开源库实现了很多著名的机器视觉算法,如HOGSIFTMSERk-meanshierarchical k-meansagglomerative information bottleneckSLIC superpixels, 和 quick shift。VLFeat开源库是用C语言写的,以确保其效率和兼容性,同时VLFeat还提供了MATLAB接口和详细的文档。

vlfeat中vl_gmm

[means, covariances, priors] = vl_gmm(mfcc, 8, 'MaxNumIterations', 20);


 

一、准备vlfeat文件,可以是二进制包,也可以是源码。如果使用windows平台的话,推荐使用二进制包。

版本:0.9.18

 

二、安装

1. 将所下载的二进制包解压缩到某个位置,如D:\盘

2. 打开matlab,输入edit startup.m创建启动文件startup.m

3. 在startup.m中编辑内容(注意,如果将vlfeat安装在不同的地方,需要将以下的”D:\”改为你所安装的地址):

run('D:\Software\vlfeat-0.9.18-bin\vlfeat-0.9.18\toolbox\vl_setup')

4. 保存并关闭startup.m文件,重新打开matlab程序,安装即成功。

 

三、验证

1. 在matlab中输入path

 

 2. 在matlab中输入vl_version,可以得到vlfeat的版本号。

 

 

有这些东西:

• The VLFeat library
SIFT example (vl_sift)
• Caltech-101running example
• Visual descriptors
PHOW feature (fast dense SIFT, vl_phow)
- Vector Quantization (Elkan, vl_kmeans, vl_kdtreebuild,
vl_kdtreequery)
- Spatial histograms (vl_binsum, vl_binsearch)
• Learning and classification
- Fast linear SVMs
- PEGASOS (vl_pegasos)
- Fast non-linear SVMs
- Homogeneous kernel maps (vl_homkermap)
• Other VLFeat features
