Recent studies on nonlocal metasurfaces have shown possibilities of optical image processing, such as edge detection, without the need for Fourier optics and have significantly reduced the form factor. However, the analo...

Unmanned Aerial Vehicles (UAVs) are in the midst of aviation’s next generation. UAVs are being utilized at an increasing rate by military and security operations and are becoming widely popular in usage for activities ...

Kacang kedelai merupakan tanaman pangan yang dapat diolah dalam berbagai olahan, seperti tempe & tahu. Indonesia mempunyai banyak varietas kedelai, varietas lokal atau impor. Meningkatnya konsumsi kedelai tersebut sangat...

Spatial differentiator is the key element for edge detection, which is indispensable in image processing, computer vision involving image recognition, image restoration, image compression, and so on. Spatial differentiat...

The article is a brief survey of the development of Information since the egyptians till nowadays when it is evident the importance of Computer science and of image Processing systems. lt analyses the evolution of each t...

Abstract Background Collagenous colitis (CC) is diagnosed histologically and is characterised by a thickened subepithelial collagen band together with inflammatory and epithelial changes. Although routine haematoxylin an...

Los requerimientos para capturar información sobre la forma del cuerpo humano están creciendo rápidamente y no solo se limitan a estudios ergonómicos o diseño, sino que también resultan de interés para aplicacione...

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...

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...

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...

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 ...

Tradicionalmente, el problema de consultas por contenido, es decir, el problema de recuperación de imágenes que resulten similares a una imagen dada de una base de imágenes fue solucionado utilizando una firma digital...

Multiwavelets are new addition to the body of wavelet theory. There are many types of symmetric multiwavelets such as Geronimo-Hardin-Massopust (GHM) and Chui-Lian (CL) multiwavelets. However, the matrix filter generatin...

En particular nos interesa la automatización de procesos de reconocimiento y clasificación de objetos que provienen de una línea industrial (de producción o packaging). Lo cual trae consigo la incorporación de compu...

This paper describes a new classification method (DER) based on evidential reasoning to which a series of modifications are added [1]. DER allows including new evidence for the classification process and defines a differ...

In this paper we present two basic modules whithin the designed scheme for retrieving images of a database from the object colour and shape in the scenes. On the one hand, we desing a new method to detect edges in colour...

Este trabajo tuvo lugar en el marco de un proyecto de colaboración entre el LIDI (Laboratorio de Investigación y Desarrollo en Informática) del Departamento de Informática preteneciente a la Facultad de Ciencias Exac...

Actualmente muchas son las áreas de aplicación que hacen uso de lo que se denomina visión computarizada. Entre ellas tenemos el análisis de imágenes médicas, el tratamiento de imágenes satelitales, automatización...

La gran variedad de material histórico y cultural almacenado en fotografías y películas antiguas corren peligro inminente de sufrir degradaciones y otras deformaciones relacionadas al paso del tiempo y factores ambien...

Se realizó un análisis de las tecnologías actuales de compresión de datos, especialmente compresión de imágenes aplicables en transmisión multimedial en ambientes de oficinas distribuido. En particular se compara...

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...
