摘要：
Exploiting the geometrical interpretation of the Haar transform as a rotation of the coordinate system by an angle pi/4, a new Haar-like transform is proposed which rotates the co-ordinate system by an angle which depends on the data. This data dependent transform gives better compression ratios for both signals and images than the Haar transform.
