一种电泳图谱图像的多重图像增强方法

The Approach of Electrophoresis Atlas Image multiple Enhance

电泳图谱被广泛应用于生命科学研究中,但通过实验设备所得到的电泳图谱图像的谱线与背景反差小、图像噪声污染严重,将影响对实验结果的判断。本文提出一种多重图像增强方法,通过改进应用灰度扩展(提高对比度)、自适应中值滤波(去除“盐”噪声)、离散小波变换(边缘增强)等多种图像增强算法,可得到理想的图像增强结果。

This essay discusses two aspects of problem which can be found in using broadly electrophoresis arias image in study of science in life： the contrast of spectral line and background is small and the image noise contaminates seriously. It can be got more ideal image enhance outcome by intensity expand （improve a contrast ratio）, adaptive filter （dislodge ＂salt＂ noise）, discrete wavelet transform （border strengthening） and combining with several methods of image enhance arithmetic than using image disposing software.
