Akshay Raj Gollahalli

Hi,

i guess it would be difficult to find the database so i can tell you how to do this in MATLAB.

so for this you need MATLAB and any image, i say 256x256 to be better you can increase it, no problem.

open the MATLAB, in the left panel browse to the image folder and type the following in the command window.

I = imread('filename.png'); % where filenname.png is your image file.

size(I)

I2 = reshape(I,[],3); % [] is actually [ ], dont put any space between it

size(I2)

now you will get you RBG in 'I2' if it is 256x256 you will get 65536x3, where 3 denotes [R,B,G] rows.

now lets export it to excel, now write the following code in the command window

filename = 'testdata.xlsx'; % lets give a name for excel document.

xlswrite(filename,I2)

now the above code should export it to excel, if by chance if it could'nt then it would export it to CSV format that you can convert it in excel.

hope this help.
