Nous montrerons à partir de L'Invention et la Trame que l’oeuvre d’AdoIfo Bioy Casares s’incrit et se produit dans un espace imaginaire, où le langage se répète lui-même. Nous sommes d’accord avec la plupart...

Complementary DNA (cDNA) microarrays are a powerful high throughput technology developed in the last decade allowing researchers to analyze the behaviour and interaction of thousands of genes simultaneously. The large am...

Segmentation is often a critical step in image analysis. Microscope image components show great variability of shapes, sizes, intensities and textures. An inaccurate segmentation conditions the ulterior quantification a...

In some cases, low resolution of those images composing a video film hinders the proper visual interpretation of its data. A typical example of this is video obtained from security cameras. There thus exists the need to ...

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...

Images compression is a widely studied topic. Conventional situations offer variable compression ratios depending on the image in question and, in general, do not yield good results for images that are rich in tones. Thi...

En los últimos treinta años se ha producido un desarrollo considerable en torno a lo que realmente podemos conocer acerca del pasado histórico del antiguo Israel en Palestina. La investigación arqueológica y la crí...

La movilización de los pobres urbanos en el marco de las organizaciones piqueteras del conurbano bonaerense ha sido materia de un doble enfoque. Una mirada de perfil etnográfico, que profundiza en las tramas asociativa...

Tissue classification in Magnetic Resonance (MR) brain images is an important issue in the analysis of several brain dementias. This paper presents a modification of the classical K-means algorithm taking into account th...

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...

Este texto ejercita una mirada sobre la relación entre arte, cuerpo y subjetividad. Analizo, resumidamente, aquí algunos problemas que he investigado sobre esta relación, bajo la perspectiva de la formación del sujet...

The identification and classification of seeds are of major technical and economical importance in the agricultural industry. To automate these activities, like in ocular inspection one should consider seed size, shape, ...

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...

Los esqueletos de Arroyo Seco 2 (Tres Arroyos, Buenos Aires), a pesar de constituir una de las muestras de restos óseos humanos más antigua y numerosa de Sudamérica (n= 44; ca. 8000-6300 años AP; Barrientos y Politis...

In this paper, an efficient algorithm for detecting frontalview faces in color images is proposed. The proposed algorithm has a special task; it detects faces in the presence of skin-tone regions such as human body, clot...

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...

Cuando en el contexto de la magia artificialis barroca se apela a modelos míticos para describir y explicar los fenómenos ópticos, esta referencia al mito se integra esencialmente al horizonte histórico-cultural de l...

In this paper, an improvement of deformable template matching algorithm for polygonal objects in grayscale images using two-dimensional deformable templates along orthogonal curves is presented. In the process of pre-com...
