Abstract :
In this paper we construct a new type of directional wavelet transform based on the lifting scheme and quincunx sampling. Based on known separable wavelet predictors we build nonseparable 2D wavelet predictors with directional properties. As example we use the resulting wavelet transform for image compression for motion blurred images.
