摘要	Normally, the image movement compensation velocity calculated and obtained by multiple parameter contains random error, so it must be processed by some filtering algorithms. Without filtering, the control precision of image movement compensation will be decreased, whice will cause bad image quality. By analyzing the statistical characteristics of error of image movement velocity, a method based on wavelet transform is proposed. For application for real-time processing and application, a structure based on moving window about decomposition and reconstruction is designed and an algorithm called threshold noise reduction by Donoho is proposed. Furthermore, the hardwae filtering chip based on SOC is designed. The SNR which can be calculated by filtering is improved by 9.78dB, which proves that the filtering works well and is fit for application of actual engineering.
