The present invention belongs to the image signal processing field, in particular a self-adapting watermark algorithm of a color image supercomplex frequency domain. Fistly, the algorithm processes a quick supercomplex Fourier transform to color carrier image, selecting proper frequency band in the ...
Hypercomplex polar Fourier analysis treats a signal as a vector field and generalizes the conventional polar Fourier analysis. It can handle signals represented by hypercomplex numbers such as color images. It is reversible that can reconstruct image. Its coefficient has rotation invariance property that...
