載入在八度

高光譜圖像用Matlab我可以看到我的圖像的第四信道，但不與八度：載入在八度

對圖像（I）的下列Matlab代碼給出

I = imread（」 ../rec3/2012R_1_1.tif'）[nr nc nb] = size（I）;
NB

它給出：

NB = 4

其中nb是信道號和I是一個64位圖像（3057x1210）

但對於Octave給出的相同圖像：

NB = 3

我應該爲了加載任何特殊的包能夠與高光譜圖像的工作？

EDIT

的imfinfo的用於倍頻的輸出：

ANS =

標量結構包含字段：

能否請您提供一個例子形象？ – Ash

也顯示代碼。 –

嗨，我只是使用：I = imread（'../ rec3/2012R_1_1.tif'）;那麼上面顯示的行 – Kristan

可以使用的功能rasterread或gdalread從mapping包讀取高光譜圖像。

pkg load mapping 
ras = rasterread("myfile.tif"); 
I = ras.data;

或

[~,~,I]= gdalread("myfile.tif");
