An approach to directional wavelet construction and their use for image compression
International Symposium on VIPromCom Video/Image Processing and Multimedia Communications - Trang 201-204
Tóm tắt
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.
