A Novel Low-Complexity and Parallel Algorithm for DCT IV Transform and Its GPU Implementation

This study proposes a novel factorization method for the DCT IV algorithm that allows for breaking it into four or eight sections that can be run in parallel. Moreover, the arithmetic complexity has been significantly reduced. Based on the proposed new algorithm for DCT IV, the speed performance has...
