Q: What image and video formats does Amazon Rekognition support?
Amazon Rekognition Image currently supports the JPEG and PNG image formats.
You can submit images either as an S3 object or as a byte array. A codec is software or hardware that compresses data for faster delivery and decompresses received data into its original form.
Amazon Rekognition Video operations can analyze videos stored in Amazon S3 buckets. The H.264 codec is commonly used for the recording, compression and distribution of video content.
A video file format may contain one or more codecs.
If your MOV or MPEG-4 format video file does not work with Rekognition Video, check that the codec used to encode the video is H.264.
You must have an Amazon Web Services account; if you do not already have one, you will be prompted to create one during the sign-up process.
Amazon Rekognition Image supports image file sizes up to 15MB when passed as an S3 object, and up to 5MB when submitted as an image byte array.
Amazon Rekognition Video supports up to 8 GB files and up to 2 hour videos when passed through as an S3 file.
Q: How does image resolution affect the quality of Rekognition Image API results ?
To achieve accurate results on complex computer vision tasks such as object and scene detection, face analysis, and face recognition, deep learning systems need to be tuned properly and trained with massive amounts of labeled ground truth data.
Sourcing, cleaning, and labeling data accurately is a time-consuming and expensive task.
