1. Uma abordagem de compressão de imagens através de sistemas de funções iteradas
A new image compression technique is proposed, based on the affine transformations (ATs) that define an iterated function system (IFS). Previous related research in the field has shown that an image may be approximated by iteratively subjecting a set of sub-regions to a group of ATs. In this case, the original image should be partitioned in regions, and each

2. HISTÓRIAS DE CONSTITUIÇÃO E AMBIENTALIZAÇÃO DE PROFESSORES DE QUÍMICA EM RODAS DE FORMAÇÃO EM REDE: Colcha de Retalhos Tecida em Partilhas (d)e Narrativas. / Stories of Chemistry Teachers Constitution and Environmentalization in Wheels of Network Education: a Patchwork Quilt Made of Narratives.
This Dissertation defends Wheels of Network Education as privileged spaces in the environmentalization of teachers who write, read, and tell their stories. Therefore, I bet on narrative and on the exercise of telling stories and sharing them in these Wheels. In the context of these stories, there are Science professors who work with interinstitutional projec

3. Realce de contraste em imagens digitais usando equalização de histograma
Nowadays devices are able to capture and process images from complex surveillance monitoring systems or from simple mobile phones. In certain applications, the time necessary to process the image is not as important as the quality of the processed images (e.g., medical imaging), but in other cases the quality can be sacrificed in favour of time.This thesis f

5. A quantitative model for transforming reflectance spectra into the Munsell color space using cone sensitivity functions and opponent process weights
This article presents a computational model of the process through which the human visual system transforms reflectance spectra into perceptions of color. Using physical reflectance spectra data and standard human cone sensitivity functions we describe the transformations necessary for predicting the location of colors in the Munsell color space. These trans
