Dynamic multiple-image encryption based on chirp z-transform
(IOP Publishing, 2019-02)
It is demonstrated a dynamic encryption scheme based on chirp − z transform (CZT). The novel design of this setup allows to protect multiple images in a multiplexed format and fully recover them without the influence of ...
Digital image compression for a 2f multiplexing optical setup
(IOP Publishing, 2016-07)
In this work a virtual 2f multiplexing system was implemented in combination with digital image compression techniques and redundant information elimination. Depending on the image type to be multiplexed, a memory-usage ...
Performance Analysis of Fuzzy Mathematical Morphology Operators on noisy MRI
(Planta Piloto de Ingeniería Química, 2014-02)
Despite a large amount of publications on Fuzzy Mathematical Morphology, little effort was done on systematic evaluation of the performance of this technique. The goal of this work is to compare the robustness against noise ...
Color measurement: comparison of colorimeter vs. computer vision system
(Springer, 2017-06)
The aim of this work was to compare two food color measurement techniques, the traditional tristimulus colorimeter and an image analysis system. In this sense a computer vision system was developed, consisting of a digital ...
Microscope cell color images segmentation by fuzzy morphological reconstruction
(SPIE Digital Library, 2017-01-26)
There are many different methods to perform gray level segmentation in microscope cell images however, in some circumstances, texture features and roughness are not as relevant as the color for the segmentation task. In ...
Transfer of multivariate classification models applied to digital images and fluorescence spectroscopy data
(Elsevier Science, 2017-07)
This work evaluates the use of transfer of classification models for identifying adulteration of extra virgin olive oil (EVOO) samples involving, separately, two analytical techniques: fluorescence spectroscopy and digital ...
General Database Infrastructure for Image Retrieval
(IJCSI, 2010-11)
In this article, a general database infrastructure implemented in an Object-Relational Database Management System for image retrieval is proposed and describe. Semantic and content based image queries can be performed with ...
New Windows based Color Morphological Operators for Biomedical Image Processing
(IOP Publishing, 2016-05)
Morphological image processing is well known as an efficient methodology for image processing and computer vision. With the wide use of color in many areas, the interest on the color perception and processing has been ...
Tuneable algorithms for tracking activity images in dynamic speckle applications
(Elsevier, 2020-06)
Herein we present a generalized algorithm for processing activity images. Existing algorithms are applicable only to particular cases, and a new, broader approach is therefore proposed here that is based on a set of tuneable ...
A survey on the low-dimensional-model-based electromagnetic imaging
(Now Publishers, 2018-06)
The low-dimensional-model-based electromagnetic imaging is an emerging member of the big family of computational imaging, by which the low-dimensional models of underlying signals are incorporated into both data acquisition ...
