“…Posteriormente, rotar la imagen con el ángulo estimado, luego, colapsar el Espectro de Potencia de Fourier 2D sobre el eje u para obtener una representación en una dimensión (1D). Por último, identificar los míni-mos relativos a partir de la derivada del espectro 1D y promediar la distancia entre ellos para estimar la longitud de la PSF [32], [33]. La Fig.…”

“…Recently the Radon transform (RT) based approach has been proposed for blur angle estimation in [10,14,4]. Instead of working directly on the spectrum of the blurred image, the method proposed by H. Ji et al in [9] explores the same cepstrum domain using the image gradients.…”

“…So the measuring precision of shipborne system is degraded due to the motion-blur of observed image. It is not very feasible to recover the image using blind deblurring method, since the relative motion is not just linear motion or central rotational motion [1][2][3]. As for high orbit target or dim target, the exposal time should be increased to some extent so as to enhance the ability and precision of observation.…”
