In this work, a multiresolution approach, based on a generalized Laplacian pyramid with p:q (i.e., rational) scale factor, is proposed to merge image data of any resolution and represent them at any scale. The resulting bands capture multispectral features with an enhanced spatial resolution. Pyramid-generating filters are assessed and normalization of pyramid layers is introduced to enhance the data fusion performance. Objective and subjective trials show the effectiveness of the proposed method.

Abstract
In this work, a multiresolution approach, based on a generalized Laplacian pyramid with p:q (i.e., rational) scale factor, is proposed to merge image data of any resolution and represent them at any scale. The resulting bands capture multispectral features with an enhanced spatial resolution. Pyramid-generating filters are assessed and normalization of pyramid layers is introduced to enhance the data fusion performance. Objective and subjective trials show the effectiveness of the proposed method.File in questo prodotto:
