Abstract(in Japanese) (See Japanese page)
Abstract(in English) In this article, we consider a problem of reconstructing an unknown binary-valued signal from incomplete linear measurements. For this problem, a method called basis pursuit has been proposed based on the sparsity of the original signals, which solves the problem by L1 norm optimization. However, this method can be applied only to signals that contains many zeros, and ignores the other value of a binary signal. To remedy this, we extend the idea of compressed sensing, and propose to solve the problem by minimizing the sum of weighted absolute values, called extended L1 norm optimization. This can be equivalently reduced to linear programming. We then apply this method to binary image (or white-black image) reconstruction. An example is shown to illustrate the effectiveness of the proposed method compared with the basis pursuit method.
