Fast DCT Domain Filtering Using the DCT and the DST

open access: yes, 1995
A method for efficient spatial domain filtering, directly in the DCT-IIe domain, is developed and proposed. It consists of using the discrete sine transform (DST), together with the discrete cosine transform (DCT), for transform domain processing, based ...

The Contingent Eco‐Innovation–Firm Performance Link: A Global Systematic Literature Review and Future Research Agenda

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT The relationship between eco‐innovation (EI) and firm performance (FP) is central to environmental management research, yet empirical evidence remains fragmented and highly context dependent. This article presents a global systematic literature review (SLR) of 541 empirical studies (2006–April 2025) to (i) diagnose the systematic sources of ...

Dopachrome tautomerase (Dct) regulates neural progenitor cell proliferation

open access: yes, 2006
DOPAchrome tautomerase (Dct) functions downstream of tyrosinase in the biosynthetic pathway of eumelanin by catalyzing the conversion of dopachrome to 5,5-dihydroxyindole-2-carboxylic acid (DHICA) in pigment cells. Dct transcription is regulated directly

A DCT-domain System for Hiding Fractal Compressed Images

open access: yes, 2010
[[abstract]]In this paper, we shall propose an approach for hiding a secret image in a cover image. In the beginning, the fractal image compression method is used to compress the secret image, and then we encrypt this compressed data by DES.
