Abstract

as prioris baseadas em contexto são utilizadas em redes de aprendizado de máquina (por exemplo, redes neurais) para detectar objetos em imagens. as localizações prováveis de objetos são estimadas com base em rótulos de contexto. uma rede de aprendizado de máquina identifica um rótulo de contexto de uma imagem inteira. com base nisso, a rede seleciona um conjunto de regiões prováveis para detectar objetos de interesse na imagem.
