In a general context we introduce image processing with 1-dimensional wavelets and show the diferences with nonseparable 2-dimensional wavelets having quincunx decimation, in the first place, and with balanced nonseparab...

Data mining is the discovery of patterns and regularities from large amounts of data using machine learning algorithms. This can be applied to object recognition using image processing techniques. In fruits and vegetabl...

The Yerba Mate quality is defined by estimating the product moisture content. This value allows adjusting the production system, by controlling the stake of the dryer to ensure the product quality. Currently this process...

The analysis and classification of seeds are essential activities contributing to the final added value in the crop production. Besides varietal identification and cereal grain grading, it is also of interest in the agri...

Digital images are digital signals captured through different means. Sometimes these captured images contain variations combined with the original signal, this variations are called noise. Echo is a particular kind of no...

In situ hybridization (ISH) method allows to reveal specific genes expression, identify specific cell types and detect areas or tissues, displaying differential gene expression. This work describes a standardized procedu...

UAV (Unmanned Airborne Vehicle) high resolution digital image acquisition systems based on small format cameras provide a versatile alternative to the solution of environmental monitoring and remote sensing problems. Thr...

Se presenta el desarrollo de un algoritmo de procesamiento de imágenes para el soporte de detección de celo vacuno. El método de detección se basa en el análisis del deterioro de pintadas lumbares, mediante la segme...

This research presents a fingerprint image processing algorithm for personal automatic identification, which has been in development since 1998. It is principally based on the comparison of the fingerprint's biometric pa...

This work presents preliminary results of a method for semi-automatic detection of fat and hematopoietic cells as well as trabecular surfaces in bone marrow biopsies, in order to calculate the percentage of each type of ...

Una de las áreas de mayor interés y crecimiento en los últimos años dentro de la informática es la de procesamiento de imágenes. Abarca distintas etapas que van desde la adquisición de los datos de entrada, el mej...

Image mining deals with the study and development of new technologies that allow accomplishing this subject. A common mistake about image mining is identifying its scopes and limitations. Clearly it is different from com...

Images from complementary DNA (cDNA) microarrays need to be processed automatically due to the huge amount of information that they provide. In addition, automatic processing is also required to implement batch processes...

Reduction of impulse noise in color images is a fundamental task in the image processing field. A number of approaches have been proposed to solve this problem in literature, and many of them rely on some multivariate me...

En trabajos previos hemos diseñado y desarrollado un software para la optimización del procesamiento de imágenes multidimensionales, el cual consiste de un algoritmo automático de desconvolución de restauración (de...

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...

La segmentación es un paso muy importante en el procesamiento de imágenes digitales. Su aplicación tiene como objetivo la subdivisión de la imagen en sus partes constituyentes u objetos. Actualmente existen diferent...

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...

Uno de los aspectos más difíciles de resolver cuando se realiza procesamiento de imágenes oculares en ambientes de diversas exposiciones lumínicas y con movimientos aleatorios de la cámara de captura, es el de homog...

Cuando se crea una imagen para comunicar una idea, se está utilizando un lenguaje visual. Podemos “visualizar” nuestro pensamiento de la misma manera en que lo verbalizamos. Un diagrama, un mapa, una pintura son eje...

El presente trabajo propone un nuevo método para el cálculo de la rotación de una pelota en situaciones de entrenamiento deportivo, cuando la misma se encuentra en la zona cercana al arco. El método propuesto reduce...

La creciente cantidad de imágenes transmitidas a través de Internet ha llevado al desarrollo de Sistemas de Minería de Imágenes de propósito general. La performance de un SMI depende en gran medida de una rápida y...
