摘要：
The LLMICT transform matrices are orthogonal, hence their inverses are their transpose. The LLMICT transform matrices are integer matrices, which can be implemented with high precision eliminating the drift error in video coding. The fast algorithms for the LLMICT transform are found, thus allowing a lower requirement on computation hardware. The LLMICT is also found to have high transform coding gain due to its similarity to the DCT.
