Abstract
resumo patente de invenção: "técnicas de estabilização de imagem para sistemas de vigilância por vídeo". a presente invenção refere-se a um sistema de reconhecimento comportamental que pode incluir tanto um mecanismo de visão do computador como um mecanismo de aprendizado da máquina configurados para observar e aprender padrões de comportamento em dados de vídeo. algumas concretizações podem proporcionar estabilização de imagem de um fluxo de vídeo obtido a partir de uma câmera. um módulo de estabilização de imagem no sistema de reconhecimento comportamental obtém uma imagem de referência a partir do fluxo de vídeo. o módulo de estabilização de imagem identificar regiões de alinhamento dentro da imagem de referência baseado nas regiões da imagem que são densas com aspectos. ao determinar que os aspectos rastreados de uma imagem corrente estão fora de alinhamento com a imagem de referência, o módulo de estabilização de imagem utiliza a região de alinhamento com aspectos mais densos para estimar uma matriz de transformação afim para aplicar para toda a imagem corrente para distorcer a imagem em alinhamento apropriado.
