This work introduces an affine shear tight frame with 2 layers of high-pass framelets. The frame is generated by two set of generators which are meat to cover the inner and outer layers of high-pass bands in order to capture edge and texture features respectively. A characterization is given of the frame being a tight frame. A low redundancy fast transform is implemented, and tested on image/video denoising and inpainting tasks.
