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.
A second-degree burn is one that affects the outer two layers of skin. The epidermis (outer layer) and dermis (the layer underneath) both sustain injury in a second-degree burn. This type of burn may be minor or it may be more serious, depending on the size of the area burned and where on the body the burn occurs. Minor second-degree burns may be self-treated; major ones require immediate medical attention. A second-degree burn usually takes no more than a few weeks to heal. If it is a minor burn, it may not leave a noticeable scar. However, a deeper burn of this type may result in scarring or even contractures near joints.
