ake the definition of a 2D DCT given in the slides for Module 8: C[k1,k2]=∑n1=0N−1∑n2=0N−1x[n1,n2]cos[πN(n1+12)k1]cos[πN(n2+12)k2]. Assume that pixel values x[n1,n2] take on the integer values between 0 and 255. Question : If 2D DCT is taken on blocks of size 8×8 (N=8), give the range (minimum and maximum possible value) in which the DCT coefficients lie.
