1. Algorithm for predicting macular dysfunction based on moment invariants classification of the foveal avascular zone in functional retinal images
Abstract Introduction A new method for segmenting and quantifying the macular area based on morphological alternating sequential filtering (ASF) is proposed. Previous studies show that persons with diabetes present alterations in the foveal avascular zone (FAZ) prior to the appearance of retinopathy. Thus, a proper characterization of FAZ using a method of

3. Arquitetura para extração de características invariantes em imagens binárias utilizando dispositivos de lógica programável complexa / Architectures for the extraction of invariant characteristics from binary images using logic programmable devices
A challenge for digital systems designers is to meet the balance between speed and flexibility was always. FPGAs and CPLDs where used as glue logic, reducing the number of components in a system. The use of programmable logic (CPLDs and FPGAs) as an alternative to microcontrollers and microprocessors is a real issue. Moments of the intensity function of a gr

4. Modelamento mecanico-quantico de tensores polares
Experimental polar tensors for the CH2Cl2, CF2Cl2, CF3Cl, CFCl3, CH3F, CH3Cl, CH3I, Cl2CO, F2CO, Cl2CS and F2CS molecules were determined with the aim of testing previously established electronegativity models for tensor invariants estimation. The method of determination uses comparison of the several possible sets of polar tensors for a molecule (correspond
