摘要:
An image transformation method substitutes element based on a trigonometric function included in a discrete cosine transform (DCT) matrix with a rational number, performs upscaling and transformation process on an input signal using the substituted DCT matrix based on a maximum value of a denominator of an intermediate value generated in the transformation process, and performs downscaling on the transformed signal.
