High and Low Pass Filters Based on Schrdinger Transformation of Image
【摘要】 研究了粒子的载流子K(b,a)所满足的薛定谔方程的数值解及分析解,引入了图像的I-型与II-型薛定谔变换,解释了变换的意义,给出了薛定谔变换的性质。利用图像薛定谔变换,构造出了一种滤波效果较好的高通与低通滤波器,实现了图像的边缘检测、图像平滑及增强。
【Abstract】 We discussed analytical and numerical solutions of the Schrdinger Equation,which is satisfied by the propagator P(b,a).We introduced definition of I-Type and II-Type Schrdinger transformation of image and explained their meaning and nature of transformation.Properties of Schrdinger transform was given.High and low pass filters based on Schrdinger transformation of image were obtained.Image smoothing,edge detect and image enchancement were implemented.
