image processing using matlab

[manjumehta]

suppose we have image I then what is meant by I)?

 

[soumen1]

suppose I is RGB image of 128X128 pixels then I will be a 3 dimensional matrix of 128X128X3

and if will type I) in the matlab command window the resultant matrix will be of 49152 X 1 (because 128X128X3=49152)

The statement is nothing but conversion of a multidimensional variable to a one dimensional comlumn matrix....matlab works on column matrices.
