Oblique striping removal in remote sensing imagery based on wavelet transform

摘要

Oblique sharp and repetitive stripes in remote sensing imagery can distractingly and obstructively affect the interpretation and application of remote sensing data. A new methodology for removing oblique stripes, based on discrete wavelet transform (DWT), is proposed. DWT has been used to transform a multispectral image into a frequency domain to find the frequency components caused by stripes. The new technique has been tested taking CMODIS imagery as an example and evaluated by a number of indices. The results show that the proposed method can remove oblique stripes effectively and keep most image information.
