摘要/Abstract

摘要： 当用单个图像传感器采集彩色图像时需要一个彩色滤光阵列（Color Filter Array）,这个阵列覆盖在图像传感器前面。由于彩色滤光阵列使图像传感器的每个像素只能感测一种颜色分量,所以在复原全彩色图像时必须利用颜色分量插值方法。提出了加权平均插值新算法,实验表明,新的算法比现有的几种常用插值算法有了不同程度的改善。

Abstract: Color imaging with a single detector requires the use of a Color Filter Array（CFA） which covers the detector array.In this arrangement each pixel in the detector samples only one of the many-color separations.The recovery of full-color images from a CFA-based detector requires a method of calculating values of the other color separations at each pixel.These methods are commonly referred as color interpolation algorithms.A new improved algorithm is proposed.The data of experiments indicates that the new algorithm is better than the existing algorithms to some extent.
