Suppose v is a 256-pixel one-dimensional image whose unnormalized Haar wavelet transform, q = has only three non-zero elements: 91 = 2 92 = -4 [90 91 9255], 95 = 4 Let b1, b2 and b5 be the unnormalized Haar wavelets that correspond to these elements, i.e., the wavelets whose contribution to image v is not zero. Part (a) Plot the wavelets b1, b2 and b5 as one-dimensional images on the corresponding axes below. You do not need to indicate the units of the y axis. b₁: 127 191 b2: 191 255 63 b5: 127 191 255
