发明名称 Device for the correction of images from a sensor causing a periodic noise, and implementation method
摘要 The analysis of an image of the field of observation from a heat camera by bands of n lines prompts the appearance of streaks or "striping" in certain zones of the image, all these zones constituting a "striping space". The device for the implementation of the method includes means to determine a base of orthonormal functions H and V, generating a vector space of functions for which the values taken, at each point of the image, represent the luminance values of all the types of striping, means to modelize the striping exhibited by the image in determining the coefficients of distribution of this striping on the basic functions, means to synthesize the striping, in determining the luminance values of the striping from the coefficients of correlation and from the values of he basic functions, and, finally, means to substract the luminance values of the synthesized striping from the luminance values of the initial image.
