According to the invention, the high-pass filter determines the correction (C,(Pr,r)) of each pixel (Pr,r; Px,x) on the basis of a mean of the intensities of at least pairs of pixels being next to, that is at predetermined distances from and on opposite sides of the filtered pixel...
After analyzing the advantages and disadvantages of the theory and algorithms of IHS method and high pass filter method,this paper put forward a high pass filter method for image fusion based on IHS transformation.The algorithm first filtered the component I obtained by IHS transforming of multi-sp...

Mean filter is used to remove the Gaussian noise from the image. Edge pixels are lost due to the mean filtering operation. Edges are preserved with the help of the specialized architecture. Preserved edges are recombined with mean filtered image to improve the image quality. Filter structure is...

image pixel was normalized by its mean and then band-pass (0.005--0.1 Hz) filtered to remove the DC component, linear drift and high frequency noise... Xiao Wang,Xiao-Hong Zhu,A. Divani,... 被引量: 0发表: 2013年 加载更多 研究
Step 2: The selection of the appropriate high-pass cut-off frequency for filtering to remove the low-frequency noise, starting from 0.01 Hz and increasing the high-pass cut-off frequency with every step of 0.01 Hz. Step 3: The integration of filtered acceleration time series into velocity and...
