Abstract
A non-dyadic spatial scalable wavelet transform may scale an original digital video frame or digital image at a non-dyadic ratio. The digital video frame or digital image is quantized to create a set of data representing the digital video frame or digital image. The set of data is then input to the non-dyadic spatial scalable wavelet transform. The non-dyadic spatial scalable wavelet transform may then transform the data associated with a first pixel to a high-pass coefficient and use the high-pass coefficient to transform the data associated with a second and third pixel to low-pass coefficients. The low-pass coefficients may then be converted to a digital image for viewing.
