改进的Floor函数对双线性插值算法精度的影响

Effects of Improved Floor Function on the Accuracy of Bilinear Interpolation Algorithm

Olivier Rukundo

摘要:

在这项研究中,标准的IEEE 754 2008和基于模的地板功能的四舍五入非整数已经提出。证明了它们对双线性插值算法精度的影响。改进的地板使用模运算,努力使每个非整数加数的整数之间的乘法逆的分数因子和分子之间的余数是大于零。实验表明,改进的地板功能和替代标准的圆形功能的相对积极的影响。

英文摘要:

In this study, the standard IEEE 754 2008 and modulo-based floor functions for rounding non-integers have been presented. Their effects on the accuracy of the bilinear interpolation algorithm have been demonstrated. The improved floor uses the modulo operator in an effort to make each non-integer addend an integer when the remainder between the multiplicative inverse of the fractional factor and the numerator is greater than zero. The experiments demonstrated relatively positive effects with the improved floor function and the alternativeness to the standard round function.
