【摘要】 提出了实现图象几何变换的迭代函数系统（ＩＦＳ）参数修改法，导出了实现图象平移、旋转和缩放的ＩＦＳ参数变换公式。这种方法的基本思想是通过修改图象的ＩＦＳ码而实现对该ＩＦＳ的吸引子（原图象的逼近）进行几何变换。实验结果表明本文所提方法正确，易于实现更多还原

【Abstract】 A novel image geometry transformation method based on modifying IFS coefficients is proposed. Formulas for modifying IFS parameters to translate, to rotate and to dilate images are presented. Using this method to geometrically transform images is to transform the fractal attractor, approximation of the original image, of the corresponding IFS by altering the IFS coefficients. The experimental results indicate that the method works well and is simple to be realized.更多还原
