Algorithm 13 INV_SHIFT_TILES(stiles, R, C, x, r)
Input : stiles - a list containing the shifted tiles R - the number of rows in the grid of tiles C - the number of columns in the grid of tiles x - initial value for the shuffling pattern r - constant value for shuffling Output : temp - a list containing the inverted shifted tiles Initialize temp ← None with length R * C index ← GenerateImageShufflingPattern(x, r, R, C) For i from 0 to R * C - 1 do temp[index[i]] ← stiles[i] Return tem |
