    Fast data-independent KLT approximations based on integer functions

    The Karhunen-Loève transform (KLT) stands as a well-established discrete transform, demonstrating optimal characteristics in data decorrelation and dimensionality reduction. Its ability to condense energy comp...

    Efficient Computation of the 8-point DCT via Summation by Parts

    This paper introduces a new fast algorithm for the 8-point discrete cosine transform (DCT) based on the summation-by-parts formula. The proposed method converts the DCT matrix into an alternative transformatio...
