چکیده

O registro de imagens é um problema comum na visão computacional com diversas aplicações que consiste em encontrar a correta transformação entre pares se sobrepõem. Neste trabalho objetiva-se apresentar modelo automático e preciso para utilizando o descritor SIFT método estimação RANSAC adaptado. ocorre através da estimativa homografia os imagens, utilizam as correspondências pontuais dadas pelo SIFT. As são classificadas usando limiar erro estimado dinamicamente. A análise considera dispersão do resíduo vários limites adota aquele minimiza magnitude erro. testado 8 heterogêneos divididos dois grupos: 4 obtidos uma câmera profissional comum. Devido à alta qualidade das primeiro grupo, poucas iterações necessárias correta. No segundo mostrou capaz construir mosaicos sobreposição inferior 20%, encontrando exatas independentemente aquisição. Além disso, foi lidar até 65% corrupção correspondências, tempo total execução alguns segundos.

-SIFT: -Dimensional Scale Invariant Feature Transform

We propose the -dimensional scale invariant feature transform ( -SIFT) method for extracting and matching salient features from scalar images of arbitrary dimensionality, and compare this method’s performance to other related features. The proposed features extend the concepts used for 2-D scalar images in the computer vision SIFT technique for extracting and matching distinctive scale invarian...

Scale Invariant Feature Transform (SIFT): Performance and Application

In 2004, David G. Lowe published his paper “Distinctive Image Features from ScaleInvariant Keypoints” (Lowe, 2004, [2]), outlining a method he developed for finding distinctive, scale and rotation invariant features in images that can be used to perform matching between different views of an object or scene. His method, Scale-Invariant Feature Transform (SIFT) combines scale-space theory and fe...

π-SIFT: A Photometric and Scale Invariant Feature Transform

For many years, various local descriptors that are insensitive to geometric changes such as viewpoint, rotation, and scale changes, have been attracting attention due to their promising performance. However, most existing local descriptors including the SIFT (Scale Invariant Feature Transform) are based on luminance information rather than color information thereby resulting in instability to p...

Research Progress of the Scale Invariant Feature Transform (SIFT) Descriptors

The SIFT (Scale Invariant Feature Transform) is a computer vision algorithm that is used to detect and describe the local image features. The SIFT features are robust to changes in illumination, noise, and minor changes in viewpoint. The SIFT features have been used object recognition, image retrieval and matching, and so on.. The research of SIFT descriptors and improved SIFT descriptors is im...
