Detector fails for this image. It work if the image is resized.

@weltonrodrigo The variant of the s3fd included is not run across multiple scales as such very large images may have their faces omitted. Furthermore this may also lead to an out of memory error. As an workaround you can either (1) resize the image, (2) detect the faces offline and just pass their location or (3) incorporate a better/faster face detection method.

Changed the title just for the sake of google.

can you give some thumb rules for acceptable image sizes?

Just from my test: image sizes no bigger than 256x256 px work fine.
