- Image restoration of blurring due to rectilinear motion: constant velocity and constant acceleration J. S. Pérez Huerta G. Rodriguez Zurita Física, Astronomía y Matemáticas Fourier optics Image forming and processing modulation and optical transfer functions If a relative motion exists between a given objects image and a recording medium (such as a photographic film) during exposure, the recordedimage will be blurred. This effect can be expressed by an impulse response in irradiance function and the respective image restoration is madepossible by a post-recording process. General one-dimension motion is considered here. Two cases are discussed: constant velocity motionand constant acceleration motion. Image simulations representing those degradation mechanisms are shown, as well as the correspondingrestored images after using the method which is described in this work. This method is based on Dirac delta function propreties. We alsoshow real digital images affected by those motions. It can be experimentally obtained by using an air-rail. The blurred images are processeddigitally by spatial filters given by the proposed method. Numerical and experimental results are shown. 2005 artículo científico 0035-001X https://www.redalyc.org/articulo.oa?id=57064009 https://www.redalyc.org/journal/570/57064009/ https://www.redalyc.org/journal/570/57064009/html/ https://www.redalyc.org/journal/570/57064009/57064009.epub https://www.redalyc.org/journal/570/57064009/movil en http://www.redalyc.org/revista.oa?id=570 Revista Mexicana de Física application/pdf Sociedad Mexicana de Física A.C.
