Low-complexity Multidimensional DCT Approximations

open access: yes, 2023
In this paper, we introduce low-complexity multidimensional discrete cosine transform (DCT) approximations. Three dimensional DCT (3D DCT) approximations are formalized in terms of high-order tensor theory.

New Proposed Fusion between DCT for Feature Extraction and NSVC for Face Classification

open access: yesCybernetics and Information Technologies, 2018
Feature extraction is an interactive and iterative analysis process of a large dataset of raw data in order to extract meaningful knowledge. In this article, we present a strong descriptor based on the Discrete Cosine Transform (DCT), we show that the ...
