Reconocimiento de dígitos escritos a mano mediante métodos de tratamiento de imagen y modelos de clasificación

Resumen. El ROC (Reconocimiento Óptico de Caracteres) es una línea de investigación dentro del procesamiento de imágenes para la que se han desarrollado muchas técnicas y metodologías. Su objetivo principal consiste en identificar un carácter a partir de una imagen digitalizada que se representa como un conjunto de píxeles. En este trabajo realizamos para el ROC un proceso iterativo que consta ...

Ultrasound Appearance of Juvenile Xanthogranuloma Imagen ecográfica de xantogranuloma juvenil

We present a 7-year-old girl with no past history of interest, who was seen for an asymptomatic lesion that had arisen in the right axilla 3 months earlier and had grown progressively, but that had remained stable after a cycle of cryotherapy in her health center 2 months earlier. Examination revealed a well-defined oval papule in the right axilla. The papule was of yellowish color centrally an...

Modelo foveal rectangular a partir de un sensor de imagen comercial

This work proposes the implementation of the rectangular model foveal to the image generated in a conventional sensor. The main problem in foveal sensors based on the log polar model is that each photosensor is designed with different geometries and sizes. Conventional sensors have a distribution of M by N pixels in a rectangular array, whereas in foveal models, the elements of imagen are distr...
