Abstract

Para diversas aplicaciones se perfora el papel mediante diversos métodos consiguiendo perforaciones de muy pequeño tamaño. Por otra parte se marca el papel a efectos estéticos con rayas de distinto grosor e intensidad. Este dispositivo hace un análisis tanto de los agujeros como de las rayas. El dispositivo consiste en: Un scanner de diapositivas mediante el cual se obtiene una imagen por transmisión. La muestra del papel a analizar es montada en una diapositiva e introducida en el scanner. La imagen es analizada estableciendo el área de cada perforación, el número de perforaciones, el valor medio y la distribución estadística. Por otra parte el sistema mide la anchura de las rayas, la separación entre ellas y la intensidad relativa entre las zonas en el interior de las rayas y entre ellas.For various applications, the paper is perforated by various methods, obtaining perforations of very small size. On the other hand, the paper is marked for aesthetic purposes with stripes of different thickness and intensity. This device analyzes both the holes and the stripes. The device consists of: A slide scanner through which an image is obtained by transmission. The sample of the paper to be analyzed is mounted on a slide and inserted into the scanner. The image is analyzed by establishing the area of each perforation, the number of perforations, the average value and the statistical distribution. On the other hand, the system measures the width of the stripes, the separation between them and the relative intensity between the areas inside the stripes and between them.

Breve explicación de la invenciónBrief Explanation of the Invention

Para diversas aplicaciones se perfora el papel mediante diversos métodos consiguiendo perforaciones de muy pequeño tamaño, el sistema mide sus áreas y hace un cálculo estadístico de la distribución de tamaños para una área de papel determinada. Por otra parte el sistema mide la anchura de las rayas, la separación entre ellas y la intensidad relativa entre las zonas en el interior de las rayas y entre ellas. El sistema consta de scanner, y ordenador que utiliza un programa que realiza las medidas del tamaño de las perforaciones y su estadística, también analiza las rayas.For various applications the paper is perforated by various methods getting very small perforations size, the system measures its areas and makes a statistical calculation of the size distribution for a given paper area. By other part the system measures the width of the stripes, the separation between them and the relative intensity between the areas inside of the stripes and between them. The system consists of scanner, and computer that uses a program that performs the measurements of the size of the perforations and their statistics, also analyzes the stripes.

El dispositivo consta de dos partesThe device consists of two parts

a)to)
Un scanner de diapositivas mediante el cual se obtiene una imagen por transmisión. Una muestra del papel a analizar es montada en una diapositiva e introducida en el scanner.A slide scanner through which an image is obtained by transmission. A sample of the paper to be analyzed is mounted on a slide and inserted into the scanner.

b)b)
Un ordenador que analiza las imágenes que provienen del scanner, utilizando algoritmos de compensación de la difracción y binarización sobre imágenes de 512X512 pixeles.A computer that analyzes the images that come from the scanner, using diffraction compensation algorithms and binarization on 512X512 pixel images.

La imagen es analizada estableciendo el área de cada perforación, el número de perforaciones, el valor medio y la distribución estadística. Por otra parte el sistema mide la anchura de las rayas, la separación entre ellas y la intensidad relativa entre las zonas en el interior de las rayas y entre ellas. Los resultados obtenidos aparecen en la pantalla del ordenador.The image is analyzed by establishing the area of each perforation, the number of perforations, the average value and the statistical distribution On the other hand the system measures the width of the stripes, the separation between them and the relative intensity between the areas inside the stripes and between them. The Results obtained appear on the computer screen.
