Requirements for sending face images
The Datavalid Facial Recognition module requires images with a minimum resolution of 250 x 250 pixels. The service accepts JPG and PNG images. The precision index of the algorithm depends directly on the quality of the image sent. The minimum resolution of 250 x 250 px refers to the face image area, not the total area (blank background, if any). \
Face image quality
We recommend the ICAO standard as reference for the required quality for the photos. Please check below some examples of bad quality face photos, which must be avoided. For the cases of bad quality photos, is not possible to guarantee the accuracy of the images comparison.
Requirements for sending digital images
The Datavalid Digital Validation module requires images with a minimum resolution of 500 DPI (dots per inch). We recommend an image with dimensions of 640 x 600 pixels in height X width (considering the image before being cropped). WSQ and PNG formats are supported.
