This paper investigates Y UV -to-RGB color space conversion on FPGA-augmented TriMedia-32 processor. First, we outline the extension of TriMedia-32 architecture consisting of FPGA-based Reconfigurable Functional Units (RFU) and associated generic instructions. Then we analyse a YUV-RGB (RFU–specific) instruction which can process four pixels per call, and propose a scheme to implement the YUV-R...

Nucleosynthesis in evolved (RGB and AGB) low-mass stars is reviewed under the light of the reaction rates recommended in the NACRE compilation (Angulo et al. 1999). We use a parametric model of stellar nucleosynthesis to investigate the uncertainties that still exist nowadays on the nuclear data and to give a critical point of view on the resulting evolution of the chemical abundances. We discu...

The spectral-based characterization of inkjet printers is often based on a physical description of the printing process, but our experience tells us that it is not unusual to be unable to fit a mathematical model to a given printer. The objective of our work is to see whether the use of methods such as genetic algorithms and neural networks is an effective strategy to approach the complex probl...

This paper presents an algorithm for detecting nudity in color images. A skin color distribution model based on the RGB, Normalized RGB, and HSV color spaces is constructed using correlation and linear regression. The skin color model is used to identify and locate skin regions in an image. These regions are analyzed for clues indicating nudity or nonnudity such as their sizes and relative dist...

In this paper we propose a challenging new computer vision task of inferring Bread Units (BUs) from food images. Assessing nutritional information and nutrient volume from a meal is an important task for diabetes patients. At the moment, diabetes patients learn the assessment of BUs on a scale of one to ten, by learning correspondence of BU and meals from textbooks. We introduce a large scale d...

An algorithm is proposed for the spectral and colorimetric characterization of digital still cameras (DSC) which allows them to be used as tele-colorimeters with CIE–XYZ color output, in cd/m2. The spectral characterization consists in the calculation of the color-matching functions from the previously measured spectral sensitivities. The colorimetric characterization consists in transforming t...

This paper describes the fusion of information extracted from multispectral digital aerial images for land use classification. The proposed approach integrates spectral classification techniques and spatial information. The multispectral digital aerial images consist of a high resolution panchromatic channel as well as lower resolution RGB and NIR channels and form the basis for information ext...

The aims of this study were to investigat...

Blood pressure is a fundamental health metric widely employed to predict cardiac diseases and monitor overall well-being. However, conventional blood measurement methods, such as the cuff method, necessitate additional equipment can be inconvenient for regular use. This study aimed develop novel approach using only an RGB camera, which promises enhanced convenience accuracy. We U-Net Basic gene...
