Abstract

Image interpolation using radial basis function (RBF) neural networks is accomplished. In this work the RBF network is first trained with the given image, satisfying the constraint of the gray value at each pixel. With the desired magnification ratio, each pixel is then divided into subpixels. The subpixel gray values are calculated using the trained network. Two dimensional Gaussian basis functions are used as the neurons in the hidden layer.
基于径向基函数神经网络的高保真图像插值
利用径向基函数(RBF)神经网络实现图像插值。在这项工作中,RBF网络首先使用给定的图像进行训练,满足每个像素的灰度值约束。使用所需的放大倍率,然后将每个像素划分为子像素。利用训练好的网络计算亚像素灰度值。隐藏层采用二维高斯基函数作为神经元。
