Carreras Béjar, Carmen ; Chevalier del Río, Margarita ; Calvo Padilla, María Luisa | SPIE--The International Society for Optical Engineering | 1984In this paper, we present a theoretical model for the transmission function of a biological cell. Three different cases have been considered: a) Real transmission function, b) Pure phase Object, c) Mixed case where both, real and complex terms a[...]texto impreso

Sanz, Inmaculada ; Calvo Padilla, María Luisa ; Chevalier del Río, Margarita | SPIE--The International Society for Optical Engineering | 1998The presence of degraded or soft edges on a scene or digital image may cause ambiguities in depth perception(1,2). This kind of edges has been analyzed by introducing a mathematical model to digitally implement a large category of degraded edges[...]texto impreso

Carreras Béjar, Carmen ; Calvo Padilla, María Luisa ; Chevalier del Río, Margarita | SPIE--The International Society for Optical Engineering. | 1985In preceding works, a theoretical model has been introduced for the transmission function of a biological cell, in which the physical effects of the three transmission functions for the cytoplasm, the nucleus and the cellular membrane have been [...]texto impreso
Manzanares Ituarte, Ana ; Calvo Padilla, María Luisa ; Chevalier del Río, Margarita ; Lakshminarayanan, Vasudevan | The Optical Society Of America | 1997-07-01A revised formulation of the image Light distribution of an incoherent line source proposed by Steel [Rev. Opt. 31, 334-340 (1952)] is presented. Analytical and numerical results based on this new representation are given. We explicitly show tha[...]texto impreso
Carreras Béjar, Carmen ; Chevalier del Río, Margarita ; Calvo Padilla, María Luisa | The Optical Society Of America | 1984In this paper we present a theoretical model for the transmission function of a biological cell. Three different cases are considered: real transmission function, pure phase object, general case, where both real and complex terms are present in [...]texto impreso
Sanz, Iván ; Chevalier del Río, Margarita ; Lakshminarayanan, Vasudevan | Academic Press Inc. / Elsevier Science | 2001-09Observer sensitivity to edge blur has been examined by experimental measurements of threshold blur as a function of contrast. An extension of previous results from Watt and Morgan for high-contrast blur edges is discussed and analyzed. We propos[...]texto impreso
Mondal, Pronab K. ; Chevalier del Río, Margarita ; Calvo Padilla, María Luisa | SPIE--The International Society for Optical Engineering | 1990We define a resolution criterion for the case of two narrow line images. For doing so, we have considered the two lines as superposition of gradients of two Heaviside step-functions.texto impreso

Mondal, Pronab K. ; Calvo Padilla, María Luisa ; Chevalier del Río, Margarita ; Lakshminarayanan, Vasudevan | The International Society of Optical Engineering (SPIE) | 1991Resolution criteria for resolving two line images under coherent and incoherent illumination are presented. This technique has been used to interpret psychophysical data obtained from hyperacuity paradigms.
