Container for the parameters to the DetectText operation. Detects text in the input image and converts it into machine-readable text.
Pass the input image as base64-encoded image bytes or as a reference to an image in an Amazon S3 bucket. If you use the AWS CLI to call Amazon Rekognition operations, you must pass it as a reference to an image in an Amazon S3 bucket. For the AWS CLI, passing image bytes is not supported. The image must be either a .png or .jpeg formatted file.
The DetectText
operation returns text in an array of TextDetection elements,
TextDetections
. Each TextDetection
element provides information about
a single word or line of text that was detected in the image.
A word is one or more script characters that are not separated by spaces. DetectText
can detect up to 100 words in an image.
A line is a string of equally spaced words. A line isn't necessarily a complete sentence.
For example, a driver's license number is detected as a line. A line ends when there
is no aligned text after it. Also, a line ends when there is a large gap between words,
relative to the length of the words. This means, depending on the gap between words,
Amazon Rekognition may detect multiple lines in text aligned in the same direction.
Periods don't represent the end of a line. If a sentence spans multiple lines, the
DetectText
operation returns multiple lines.
To determine whether a TextDetection
element is a line of text or a word, use
the TextDetection
object Type
field.
To be detected, text must be within +/- 90 degrees orientation of the horizontal axis.
For more information, see Detecting text in the Amazon Rekognition Developer Guide.
