摘要：
The JPEG2000 coding scheme is slowly getting into use in imaging applications. The standard offers a set of new features and a better compression efficiency compared to the baseline JPEG. It requires, however, a high computational cost, making its usage in constrained devices, such as mobile phones or PDAs, challenging. We present a pre-compression rate allocation technique to reduce the encoding complexity and help adoption of JPEG2000 in such contexts.
