One of the advantages of the Discrete Wavelet Transform (DWT) compared to Fourier Transform (e.g. Discrete Cosine Transform DCT) is its ability to provide both spatial and frequency localization of image energy. However, WT coefficients, like DCT coefficients, are defined by magnitude as well as sign. While algorithms exist for the coding of wavelet coefficients magnitude, there are no efficien...
Histopathologic Description: Cervical spinal cord: Microscopically, the lesions are characterized by a loss of myelin visible on HE-stained sections where the normally intense eosinophilia of the white matter is lost and the neuropil to has a fine fibrillar meshwork pattern dotted with numerous oligodendrocyte nuclei. With the Luxol fast blue stain, the deep blue color of the white matter is re...
