Lines: 8 I have come across some early papers on using Hadamard Transform for image compression due to the smaller amount of computations required as compared to DFT and DCT. However the DCT has emerged as the popular choice. Can someone point out to me what are the demerits of the Hadamard transform in the application of image compression? References are welcome. Thanks.
