%這段代碼對內(nèi)存很高，所使用圖片盡量控制在200*300范圍內(nèi)


img_name=‘去霧.jpg‘;
%?原始圖像
I=double（imread（img_name））/255;

%?獲取圖像大小

[hwc]=size（I）;
win_size?=?7;
img_size=w*h;
dehaze=zeros（img_size*c1）;
dehaze=reshape（dehazehwc）;


figure?imshow（I）;
%?win_dark=zeros（img_size?1）;

%?%這段代碼可用矩陣處理
%?for?cc=1:img_size
%????win_dark（cc）=1;
%?end
win_dark?=?ones（hw）;
%?win_dark=reshape（win_darkhw）;

%計算分塊darkchannel，此處也嘗試用矩陣處理，循環(huán)太多
