二阶振荡粒子群算法，提高算法的全局收敛性(SecVibratPSO)

matlab learning by hasn

Many synthetic aperture radar (SAR) image formation algorithms require the computation of a multidimensional Fourier transform of irregularly-sampled or unequally-spaced data samples. We apply a recently developed algorithm, the unequally-spaced FFT (USFFT),2 to SAR image formation and compare its accuracy and complexity to a conventional algorithm. We find that the USFFT algorithm allows comparable accuracy to traditional approaches at a slightly reduced computational cost. We briefly discuss extensions of the USFFT algorithm to multiresolution SAR imaging

retinex阴影去除 non linear processing on the image by the commercial camera used Sensors are not Dirac Delta Functions but narrow band Approximate invariant angle is obtained by the entropy minimization mehtod. Exact angle can only be found by camera calibration method(retinex shadow removing，non linear processing on the image by the commercial camera used Sensors are not Dirac Delta Functions but narrow band Approximate invariant angle is obtained by the entropy minimization mehtod.
