 
 <prompt> Which one no be method of video compression: matching pursuit, DWT, or ISO? Given the previous question, write a context wey contain the answer. E fit be 1 - 20 sentences. Context: <response>: ```Today, almost all di video compression methods wey pipo dey use well well (e.g., those wey dey for standards wey ITU-T or ISO don approve) dey use discrete cosine transform (DCT) to reduce spatial redundancy. Di DCT wey dem dey use well well for dis matter na N. Ahmed, T. Natarajan and K. R. Rao introduce am for 1974. Oda methods like fractal compression, matching pursuit and di use of discrete wavelet transform (DWT) don dey research, but dem no dey use am for practical products (except for di use of wavelet coding as still-image coders without motion compensation). Interest for fractal compression dey reduce, because recent theoretical analysis don show say dem no too effective like dat.```
