Abstract
The separable low complexity 2D HMM proposed in [1] builds on the assumption of conditional independence in the relationship between adjacent blocks. The authors view this assumption as the key assumption to reduce the complexity. In this communication, we show that this key assumption is entirely unnecessary.
摘要
文献[1]中提出的可分离低复杂度二维隐马尔可夫模型基于相邻块之间关系的条件独立性假设构建。作者将此假设视为降低复杂度的关键假设。在本通信中，我们表明这个关键假设完全没有必要。
