Anotação de Imagens

Configure a anotação de imagens no Potato com caixas delimitadoras, polígonos e rótulos de classificação. Oferece suporte a zoom, panorâmica, multirrótulo e pré-rotulagem assistida por IA.

O Potato oferece suporte à anotação de imagens para tarefas de classificação, detecção de objetos e rotulagem de regiões.

Dicas de Desempenho

Otimize o tamanho da imagem - Redimensione imagens grandes antes da anotação
Use JPEG para fotos - Arquivos menores, carregamento mais rápido
Use PNG para gráficos - Melhor qualidade para diagramas/capturas de tela
Habilite o carregamento sob demanda - Para grandes conjuntos de dados
Considere miniaturas - Mostre prévias nas visualizações de lista
Pré-processe de forma consistente - Normalize tamanhos e formatos
