Analysis of panorama noise and study on panorama de-noising based on linear CCD

For the purpose of improving convenience for the image processing of the panorama system based on linear CCD(charge-coupled device),de-noise the images to improve the SNR is needed.Analyzed the source of noise of the images grabbed by the panorama system,studied characteristic of the noise.Comparing the advantages and disadvantages of multiple methods of de-noising,a mean-value method of image de-noising based on wavelet soft-and-hard threshold is presented.By analyzing the experiment results,proved the reliability and availability of this method,adopted to the de-noising processing of the panorama.
