In Section 4.2, we showed that such doubly compressed I-frames may introduceartifacts in the DCT coecients and showed how these artifacts can be quantied andestimated to detect tampering. Note also that the second and third P-frame of the rstand second GOP were, in the original sequence, in dierent GOP sequences.
3rd-degree burns are full-thickness burns and will require debridement of the burned dead tissue and skin grafting to heal. In brief: A 3rd-degree burn. 1st- and 2nd-degree burns are partial-thickness burns and will heal on their own, given good wound care and good nutrition. 3rd-degree burns are full-thickness burns and will require debridement of the burned dead tissue and skin grafting to heal. 1st- and 2nd-degree burns are partial-thickness burns and will heal on their own, given good wound care and good nutrition.
However, if the burn is deep, the healing skin will be more fragile and is likely to reopen. Skin grafting may be necessary for deep second-degree burns if (1) the burn takes a long time to heal, (2) severe scarring occurs, and/or (3) the burn reopens. Third-degree burns are the most severe type, since they destroy both the outer and inner layers of the skin.
