%?IMG:
%???????IMG?is?the?input?image.

%?CELLPW?CELLPH:
%???????CELLPW?and?CELLPH?are?cell‘s?pixel?width?and?height?respectively.
%
%?NBLOCKW?NBLCOKH:
%???????NBLOCKW?and?NBLCOKH?are?block?size?counted?by?cells?number?in?x?and
%???????y?directions?respectively.
%
%?NTHET?ISSIGNED:
%???????NTHET?is?the?number?of?the?bins?of?the?histogram?of?oriented
%???????gradient.?The?histogram?of?oriented?gradient?ranges?from?0?to?pi?in
%???????‘unsigned‘?condition?while?to?2*pi?in?‘signed‘?condition?which?can

%???????the?string?‘unsigned‘?or?‘signed‘.
%
%?OVERLAP:
%???????OVERLAP?is?the?overlap?proportion?of?two?neighboring?block.
