Introduction: Early detection of diseases on bean leaves is essential for preventing declines in agricultural productivity and mitigating broader agricultural challenges. However, some bean leaf ...

Abstract: Discrete cosine transform(DCT) is one of the most powerful tools in image processing. In this paper, we show that each basis of the two dimensional discrete cosine transform (2D-DCT) is an ...

Abstract: The JPEG2000 standard uses the 2D Discrete Wavelet Transform (2D DWT), while the JPEG standard uses the 2D Discrete Cosine Transform (DCT). However, the 2D DWT has higher computational ...

This project demonstrates a core step of lossy image compression by applying the Discrete Cosine Transform (DCT) to an 8x8 matrix. Methodology The process follows these key steps: Correlation Analysis ...

This Node module is an implementation of the two-dimensional Discrete Cosine Transform (2D-DCT), and its inverse, from its very definition. It is intended for educational and research purposes. You ...
