X射线荧光弱图象的去噪与增强

NOISE REMOVING AND ENHANCEMNT OF X-RAY EXCITED FLUORESCENT FAINT IMAGE

本文分析了Ｘ射线荧光弱图象的特点，以图象直方图分析为指南，采用多帧平均、灰度分段线性变换、邻域平均等空域处理方法，取得了去噪与增强的良好效果，并实现了快速处理。

The properties of X-ray ecxited fluorescent faint image are studied in this paper. Guided byanalyzing the image histogram,using spatial domain processing methods, such as multi-frameaveraging,piecewise linear gray level transformation,neighborhood averaging etc. we have obtainedgood results of noise removing and imageenhancement,and have realized fast image processing.
