%?HOG特征由Dalal在2005?cvpr?的一篇論文中提出

%?NORMMETHOD：重疊塊中的特征標準化函數的方法
%???????e為一個設定的很小的數使分母不為0
%???????v為標準化前的特征向量
%???????‘none‘?which?means?non-normalization;
%???????‘l1‘?which?means?L1-norm?normalization;?V=V/（V+e）
%???????‘l2‘?which?means?L2-norm?normalization;?V=V/根號（V平方+e平方）
%???????‘l1sqrt‘V=根號（V/（V+e））
%???????‘l2hys‘l2的省略形式。將V最大值限制為0.2

if?nargin?????%?在DALAL論文中指出的在rows:128*columns:64情況下的最佳值，設定為DEFAULT
