Abstract-Super-resolution techniques allow co mbine mu ltip le images of the same scene to obtain an image with increased geometric and rad io metric resolution, called super-resolution image. In this image are enhanced features allowing to recover important details and informat ion. The object ive of this work is to develop efficient algorith m, robust and automated fusion image frames to obtain a super-resolution image. Image registration is a fundamental step in comb ining several images that make up the scene. Our research is based on the determination and extraction of characteristics defined by the SIFT and RA NSAC algorith ms for automat ic image registration. We use images containing characters and perform recognition of these characters to validate and show the effectiveness of our proposed method. The d istinction of this work is the way to get the matching and merging of images because it occurs dynamically between elements common images that are stored in a dynamic matrix.
The detection and recognition of plants has always been a difficult task even for connoisseurs and scholars due to the wide variety of plants found worldwide. With the advancement of technology, it has become possible to solve this problem computationally. This paper presents a method to perform plant detection and recognition from images using computer vision and artificial intelligence algorithms. The results show that the computational cost and recognition rate were satisfactory for use in controlled environments. The processing time to recognize each plant was 375 milliseconds, with an accuracy of 92%.
RESUMO-Os VANTs (Veículos Aéreos não Tripulados) são muito utilizados para realizar muitas atividades em diversas áreas. Apesar da grande evolução da tecnologia e o surgimento de modelos e marcas no mercado, a aquisição de um desses modelos comerciais ainda é bem custosa. Busca-se com este trabalho integrar tecnologias e materiais de baixo custo para propor uma solução mais viável. O trabalho tem como objetivo desenvolver um VANT autônomo de custo reduzido para realizar voos controlados seguindo uma rota estipulada. A rota é um percurso planejado (plano de voo) na estação de controle (computador em solo) cujo desenvolvimento também faz parte deste trabalho. Foi escolhido o modelo de quadrirrotor para a construção do VANT idealizado, que é uma espécie de helicóptero que possui uma estrutura em forma de "X", constituído de 4 motores acoplados com hélices em cada umas das extremidades.
