We present in this work the use of two Gaussian models that describe reflectance of two different textures for the reconstruction of tridimensional objects made of these textures. The textures of the objects are segmented using a combination of image

The recovery profile of an object is of great interest in different technical, metrological and medical applications. In this work we present a system which, through a single graphical interface, we can set grid generation, acquisition and image proc

Keratoconus is a corneal disease in which the cornea assumes a conical shape due to an irregular alteration of the internal structure of the corneal tissue and sometimes is progressive, especially in young people. Anatomically, the main signs of kera

We started our study with a group of Mexican Males with an Uncorrected Visual Acuity (UCVA) of 20/20, 20/30, and 20/40. The data was obtained using a Nidek OPD Scan ARK 10000 with the Version 1.11b of the working software. With the resulting Zernike

Based on the Lau Effect we propose a system suitable for eliminating non-periodic noise on bi-dimensional periodic structures in which a liquid crystal display (LCD) is used as a dynamic grating source. Experimental results obtained with our proposal

Dynamic noise elimination in 2-D periodic structures is achieved with a liquid crystal display used as a 2-D incoherent reconfigurable source. The method, which is based on the Lau effect, shows that under certain conditions it can be used for correc
