Currently, Mathematical Morphology (MM) has become a powerful tool in Digital Image Processing (DIP). It allows processing images to enhance fuzzy areas, segment objects, detect edges and analyze structures. The techniqu...

The present paper poses a new method for computing the rotation of a ball in sport training situations, when the ball is approaching the goal line. The proposed method significantly reduces the hardware requirements asso...

Boundary extraction is an important procedure associated with recognition and interpretation tasks in digital image processing and computer vision. Most of the segmentation techniques are based on the detection of the lo...

We consider the class of iterative shrinkage-thresholding algorithms (ISTA) for solving linear inverse problems arising in signal/image processing. This class of methods, which can be viewed as an extension of the classi...

Segmentation in biological images is essential for the determination of biological parameters that allow the construction of models of several biological problems. This helps to establish clear relationships between thos...

In this work an application of image enhancement techniques in fingerprints is presented. Digital Image-processing technology was applied to restored fingerprints with non-uniform contrast. These fingerprints corresponde...

The handwritten manuscript recognizing process belongs to a set of initiatives which lean to the preservation of cultural patrimony gathered in libraries and archives, where there exist a great wealth in documents and ev...

The development of parallel algorithms for an automatic recognition and classification of objects from an industrial line (either production or packaging) is presented. This kind of problem introduces a temporal restrict...

This paper presents a robust eye detection algorithm for gray intensity images. The idea of our method is to combine the respective advantages of two existing techniques, feature based method and template based method, a...

Skeletal age assessment is one of the important applications of hand radiography in the area of pediatric radiology. Features analysis of the carpal bones can reveal the important information for skeletal age assessment....

La Detección e Identificación Automática de Patentes de Automóviles requirió para su desarrollo, el estudio, implementación, combinación y adaptación de diversas técnicas de adquisición, representación y proce...

El objetivo principal del proyecto es el de llevar a cabo una investigación básica y aplicada en el campo del procesamiento digital de imágenes. Dentro del procesamiento de imágenes, encontramos sistemas de reconocim...

Vision based applications are present anywhere. A special market is industry, allowing to improve product quality and to reduce manufacturing costs. The vision systems applied to industries are known as machine vision sy...

En este trabajo se presentan y comparan dos técnicas de compresión de imágenes con pérdida basadas en el método usado por el Standard de compresión Joint Photographic Experts Groups (JPEG) y en el método de partic...

In this paper two images compression techniques with loss based on the method used by the compression Standard Joint Photographic Experts Groups (JPEG) and on the Quadtree adaptive partitioning method are presented and c...

The image recognizing process requires the identification of every logical object that compose every image, which first implies to recognize it as an object (segmentation) and then identify which object is, or at least w...

En los últimos tiempos, una de las áreas que despierta mayor interés y que ha tenido más auge dentro del amplio campo de la informática es la del procesamiento paralelo. El paralelismo invade no sólo las super-comp...

A través de este proyecto desarrollamos un software capaz de leer imágenes de partituras musicales desde un scanner o desde un disco, las cuales son procesadas reconociendo los símbolos musicales que se encuentran en ...
