H A Dpost_proc_semaphore.cpp23 q_block = pointer to buffer of inverse quantized DCT coefficients of type
50 buffer pointed to by q_block. The function starts out with the assumption
51 that all entries of q_block, except for the first entry (q_block[0]), are
58 (q_block[n], n = 0,..., B_SIZE-1) are non-zero, vertical blocking artifacts
62 (q_block[n*B_SIZE], n = 0, ..., B_SIZE-1) are non-zero, horizontal blocking
65 3. If any non-zero elements exist in positions other than q_block[0],
66 q_block[1], or q_block[B_SIZE], the deringing bit is enabled. Otherwise,
