Abstract For protecting directional geometric structure information, a novel basis function called multibandelets is presented in this paper. And then an image compression algorithm is proposed based on the multibandelet transform and Shannon encode. Experiments show that the multibandelets-based compression provides improvements both in visual effects and quantitative analysis, especially for the detail information containing directional geometric structures. The compared methods are multiwavelets, and those of the wavelets and bandelets with the same vanishing moments, respectively.
