Digital affine shear filter banks with 2-layer structure (DAS-2 filter banks) are developed and are appeared to be with the perfect reconstruction (PR) property. The execution of digital affine shear transforms utilizing the progress and subdivision administrators are given. The repetition rate examination demonstrates that our digital affine shear transforms have excess rate close to 8 and it diminishes regarding the number of directional channels. Numerical analyses on picture handling exhibit the upside of our DAS-2 channel banks over numerous other cutting edge outline based changes. The association between DAS-2 filter banks and affine shear tight outlines with 2-layer structure is set up. Portrayals furthermore, developments of relative shear tight edges with 2-layer structure are given.
