下載後添加目錄、編譯即可使用
addpath(genpath('ROOT\piotr_toolbox\toolbox\'))
savepath
toolboxCompile
注意編譯前需要配置好VS編譯器
工具箱包含七大部分，channels、classify、detector、filter、images、matlab、videos，後續會對每部分做詳細的說明介紹
2，測試已訓練模型
可以準備好Inria或者Caltech數據使用detector中acfDemoInria.m或者acfDemoCal.m測試，也可以直接用圖片測試
load('detector/models/AcfInriaDetector.mat')
加載的detector分爲三部分：opts、clf、info
opts保存模型相關信息
clf保存分類器信息
info保存特徵通道信息
image = imread('test.jpg')
box = acfDetect(image, detector)
figure;
im(image);
bbApply('draw', box);
