dct coefficient
Hi ,
Can any body tell me , if we have an image , how do we get the DCT coefficinets from the image , i am a begginer to DSP and i want to do DCT on an image using MATLAB, please help me how should i start , i know how Discrete cosine transform works but i dont know what to do if i have a picture ,then what is the next step to extract the block values and get the DCT coefficients, plzzz any kind sould help me.
