VOC Release 5在windows上的使用

Posted on 2016-04-29   |   In Computer Vision   |  

Introduction

Unpack it in your [PATH] and open it using Matlab. Add voc-release5 file to path in MATLAB. And you should read README in voc-release5 file firstly.
If you want to use this code, you first step is run compile.m. But voc-release5 code can only run on linux or OS X, So let’s modify source code in order to make it work on Windows.
