摘要：Frame theory plays an important role in signal processing and image processing. The shearlets provide optimally space representations for 2D functions that are smooth away from discontinuities along C-2 curves. In the note, a new sufficient condition for irregular shearlet frames is presented. This provides a theoretical foundation for the applications of shearlets in the engineering.
