El lenguaje de señas es el autóctono, utilizado por las personas sordas para comunicarse. Se compone de movimientos y expresiones realizadas a través de diferentes partes del cuerpo. En Colombia, hay gran ausencia de tecnologías encaminadas al aprendizaje e interpretación de éste; por ende, es un compromiso social, llevar a cabo iniciativas que promuevan la mejora de la calidad de vida de este grupo social del país, el cual está representado por una minoría considerable. En este artículo, se muestra el proceso de diseño e implementación de un sistema de reconocimiento de gestos no móviles mediante el entorno de Matlab y el método SIFT; a través del cual se visualiza la imagen de la letra adquirida, junto con la traducción de la misma en el lenguaje de señas colombiano, aplicando identificación de puntos claves y comparación con imágenes almacenadas en base de datos. La herramienta realiza el reconocimiento de las 20 letras no móviles de este conjunto, implementando una interfaz gráfica en Matlab para una mejor visualización, fácil acceso al sistema y uso por parte del usuario. Se comprueba una mejor respuesta del sistema mediante la utilización de un elemento estandarizado de la imagen, en este caso, un guante quirúrgico, y se propone la mejora de la herramienta aplicando métodos de redes neuronales para que posteriormente pueda ser desarrollada de forma online; generando un mayor impacto para las necesidades actuales de la población colombiana.

Pathological Image

With the development of digital image technology, judging diseases by medical image plays an important role in medical diagnosis. Mammography is the most effective imaging examination method for breast cancer at present. Intelligent segmentation and identification of breast cancer images and judging their size and classification by digital image processing technology can promote the development of clinical medicine. This paper introduces the preprocessing technology of breast cancer pathological image and medical image recognition technology of breast cancer. In order to improve the segmentation accuracy of image processing and optimize, the segmentation recognition ability in digital mammography was improved. Based on the technical basis of pathological image analysis of breast cancer, the architecture of intelligent segmentation and recognition system for breast cancer was constructed, and each functional module of intelligent system was introduced in detail. Based on digital image processing technology, filtering technology is used to reduce dryness and improve the clarity of the image. Public datasets INBreast and DDSM-BCRP were used to verify system’s performance, and it was tested on the breast cancer image test set. The experiment shows that the comprehensive performance of the intelligent segmentation and recognition system can realize the segmentation and recognition of breast cancer and has higher accuracy and interpretability, which is helpful to improve the diagnosis of doctors.

And Storage

Interest in digital image processing techniques dates back to the early 1920's, when digitized pictures of world news events were first transmitted by submarine cable between New York and London. Applications of digital image processing concepts, however, did not become widespread until the middle 1960's, when third-generation digital computers began to offer the speed and storage capabilities required for practical implementation of image processing algorithms. Since then, this area has experienced vigorous growth, having been a subject of interdisciplinary research in fields ranging from engineering and computer science to biology, chemistry, and medicine.

INTRODUCTION.- The physical properties of rock masses are greatly influenced by their internal discontinuities, like pores and fissures. So, these need to be measured as a basis for interpretation. To avoid the basic difficulties of measurement under optical microscopy and analogic image systems, the authors use S.E.M. and multiband digital image processing. In S.E.M., analog signal processing has been used to further image enhancement (1), but automatic information extraction can be achieved by simple digital processing of S.E.M. images (2). The use of multiband image would overcome difficulties such as artifacts introduced by the relative positions of sample and detector or the typicals encountered in optical microscopy.DIGITAL IMAGE PROCESSING.- The studied rock specimens were in the form of flat deformation-free surfaces observed under a Phillips SEM model 500. The SEM detector output signal was recorded in picture form in b&w negatives and digitized using a Perkin Elmer 1010 MP flat microdensitometer.
