摘要:

在许多应用中,解决带有非负约束的最小二乘问题是有意义的。本文提出了一种新的乘法迭代方法,该方法单调减少非负二次规划(NNQP)目标函数的值。该新算法具有简单的闭式形式,易于在并行机器上实现。我们证明了该新算法的全局收敛性,并将其应用于图像超分辨率和彩色图像标注问题。实验结果展示了该新算法的有效性和广泛的应用性。

英文摘要:

In many applications, it makes sense to solve the least square problems with nonnegative constraints. In this article, we present a new multiplicative iteration that monotonically decreases the value of the nonnegative quadratic programming (NNQP) objective function. This new algorithm has a simple closed form and is easily implemented on a parallel machine. We prove the global convergence of the new algorithm and apply it to solving image super-resolution and color image labelling problems. The experimental results demonstrate the effectiveness and broad applicability of the new algorithm.
