Based on theories of subwave analysis and fuzzy recognization, causes for generation of stripe noise are analysed, and an effective calculating model to pick up stripe noise background is established.

The research content is the reduction of stripe noises in THz images.

A new destriping method based on 2-D directional filtering was proposed based on the analysis of the main causes and characteristics of the stripe noises in remote sensing images.

Aiming at the obvious stripe noises existing in the images received by the high-resolution power CCD camera carried on the China-Brazil resources satellite No.

Deep research in high-frequency characteristics of pushbroom hyperspectral imager(PHI) stripe noise,in view of the disadvantages of currently common and several improved moment matching methods,an improved smooth filtering algorithm by row is proposed.

Strip noise is one of the important factors affecting the quality of the imaginary acquired from space and the further processing on information retrieving from MODIS 1B image.

But CHRIS/PROBA data is contaminated seriously by strip noise,especially the vertical strips,so destriping is the primary step of work before using it.

Because wavelet transform is preferable to detect singular point, periodicity of distribution about striping noise in wavelet coefficient are found.

According to the analysis of Fourier filtering,median filtering,jamming filtering and direction filtering,an effective method for removing the streaking noise on CBERS_1 image is developed.

This paper presents a method that can remove streaking noise better by means of direction filtering based on two dimension Fourier transform.
