ترجمه این قسمت لطفا
Such a compression process requires knowledge of all the n coefficients x, as the locations of the significant pieces of information may not be known in advance(they are signal dependent and in our example, they will tend to be clustered around edges in the image whose locations are a priori unknown) .

This paper is about a more surprising and far-reaching implication, however, which is that signal sparsity has significant bearings on the acquisition process itself.
