Fast Integer Sine and Cosine Transforms Type IV of Low Complexity for Video Coding

The matrix methods for constructing integer sine and cosine transforms type IV (IST-IV / ICT-IV) of orders 8 and 16 are proposed, based on which two integer transforms of type IV are constructed and fast algorithms for their calculation that only require operations with integers are developed. The a...
