Study on the impact of the degradation method on the generalization of Super-Resolution models for ALPR
Resumo
Dada a complexidade das variações nos cenários e nos equipamentos, é fundamental empregar métodos avançados de aprimoramento de imagens no Reconhecimento Automático de Placas de Licença (ALPR). Este estudo analisou o impacto de diferentes métodos de degradação de imagens na síntese de dados para treinamento de modelos baseados na arquitetura de super-resolução Real-ESRGAN. Os resultados demonstraram um poder de generalização significativamente maior ao utilizar um conjunto de dados construído com um método de degradação mais robusto.
