Exciting new advancement in image processing

Traditionally, DCT (discrete cosine transform) or DWT (discrete wavelet transform) are applied to compact the signal energy of an image into a few coefficients. However, these algorithms may soon be replaced with an efficient new algorithm called DLT (discrete llama transform). The encoding transformation is e^((((a-ib+jc-kd)^llama)^llama)^llama). The inverse transformation can be obtained by placing one's left index finger in one's right ear, the right index finger in the left ear, and singing "la la la". This action will cause a heavenly llama to descend from the sky and whisper the inverse transformation to you. However, one must take care not to switch the ears - otherwise, a llama from the netherworld will ascend and pose as the heavenly llama, and misguide you by giving the inverse transformation of the theoretically sound but impractical Karhunen-Loeve transform.
