СРАВНЕНИЕ ИНТЕРПОЛЯЦИОННЫХ МЕТОДОВ МАСШТАБИРОВАНИЯ РАСТРОВЫХ ИЗОБРАЖЕНИЙ

Abstract

Статья посвящается проблеме эффективного масштабирования растровых изображений. Рассматриваются и анализируются причины появления негативных эффектов, возникающих при увеличении разрешения растровых изображений. Выполнен анализ эффективности таких методов, как метод ближайшего соседа, билинейная интерполяция и бикубическая интерполяция. Рассматривается методика экспериментального исследования, приводятся результаты сравнения алгоритмов по качеству получаемых изображений и быстродействию. Итогом исследования являются рекомендации по выбору алгоритмов увеличения разрешения изображений.The article is devoted to the problem of efficient scaling of raster images. We consider some negative effects, related with scaling of raster images. Besides, we consider an analysis of several methods that are used to increase sizes of raster images. Among them are nearest neighbor algorithm, bilinear interpolation, bicubic interpolation. We consider our research methodology, and then we tell about result of algorithms comparison. We use two criteria: quality of output images and performance of algorithms. Due to this research we can tell some recommendations on the choice of algorithms for increment of raster images. It is useful because there is no single universal algorithm for efficient solution to the problem.
