Buenas !
Hoy va un post rápido. Y es del tipo de ayuda mental, ya que siempre que tengo que mostrar información relacionada a proceso de frames por segundo, tengo que buscar en mis aplicaciones anteriores.
En este caso agregare esta información al reconocimiento de imágenes con un modelo Onnx exportado desde Custom Vision. En la UWP app que he creado en post anteriores, mostrare un label con la fecha y hora, e información de FPS.
El código es muy simple, especial detalle a la linea 10

Brain Backup done!

Happy Coding!
