imhist返回錯誤與MATLAB BMP數據

Question

我有一個形象，我想計算它historgram，但是這個代碼返回錯誤給我的，

I=imread('image number one.bmp'); 
imhist(I); 

和錯誤是

??? Error using ==> iptcheckinput 
Function IMHIST expected its first input, I or X, to be two-dimensional. 

Error in ==> imhist>parse_inputs at 281 
iptcheckinput(a, {'double','uint8','int8','logical','uint16','int16','single','uint32', 
'int32'}, ... 

Error in ==> imhist at 59 
[a, n, isScaled, top, map] = parse_inputs(varargin{:}); 

欣賞任何幫助

Answer 1

我找到了解決辦法，我的照片是RGB和imhist工作僅爲2 d輸入，我只需要轉換它

0至grascale
