An improved multi-focus image fusion method based on wavelet transform is proposed. Firstly, multi-scale decomposition is performed on source images using wavelet transform to get high-frequency and low-frequency sub-images. And then, a method based on neighboring region variance weighted-average is applied to high-frequency sub-image to get the high-frequency fusion coefficient; and a method based...
Second generation bandelets transform is a new method for image asymptotically optimal approximation based on capturing the geometric content of image. Relative to the first generation bandelets, the second generation is an construction of absolute discretization which can complete the image dissection through multi-scale analysis and geometric direction analysis. Bayes is an ideal estimation method...
The existence of stripe noises seriously influences the quality of imaging spectrometer data. In this paper, the characteristic of stripe noises especially their influence on the mean value distribution of image was deeply analyzed firstly. Based on the previous analysis, two new destriping methods were proposed. The experimental result indicated that both the new methods could effectively remove...
