# OCR Results

This section describes the format of the results produced by an OCR analysis task.

## Results by Line

The following XML shows records from the `Result` track of an OCR task. The analysis engine produces one record for each line of text in the analyzed image or video frame.

If you are processing a document, then unless you have set `ProcessTextElements=FALSE`, some of the records in the `Result` track could represent text that has been extracted from text elements that were present in the document.

    <record>
      ...
      <trackname>ocr.Result</trackname>
      <OCRResult>
        <id>14565401-b521-4135-94c8-b30f02264f38</id>
        <text>rover discovers life on Mars</text>
        <region>
          <left>240</left>
          <top>31</top>
          <width>194</width>
          <height>12</height>
        </region>
        <confidence>89</confidence>
        <angle>0</angle>
        <source>image</source>
      </OCRResult>
    </record>
    <record>
      ...
      <trackname>ocr.Result</trackname>
      <OCRResult>
        <id>59dad245-c268-4506-ac42-5752dd123576</id>
        <text>discovery confirmed yesterday and announced to world press</text>
        <region>
          <left>120</left>
          <top>62</top>
          <width>434</width>
          <height>15</height>
        </region>
        <confidence>88</confidence>
        <angle>0</angle>
        <source>image</source>
      </OCRResult>
    </record>

Each record contains the following information:

- The `id` element provides a unique identifier for the line of text. The OCR analysis engine issues an ID for each detected appearance of a line of text. If you are running OCR on video and consecutive frames show the same text, all records related to that appearance will have the same ID.

  For example, if text appears in the same location for fifty consecutive video frames, the engine uses the same ID for each record in the data track and produces a single record in the result track. The record in the result track will have a timestamp that covers all fifty frames.

  If the text moves to a different location on the screen, or disappears and then reappears, the engine considers this as a new detection and produces a new ID and a new record in the result track.

- The `text` element contains the text recognized by OCR.
- The `region` element describes the position of the text in the ingested media. If the record represents a text element that has been extracted from a document, the region is accurate only if the source media was a PDF file. Position information is not extracted from other document formats.
- The `confidence` element provides the confidence score for the OCR process (from 0 to 100). For text that was extracted from a text element in a document, the confidence score is always `100`.
- The `angle` element gives the orientation of the text (rotated clockwise in degrees from upright).
- The source element specifies whether the text originated from an image or video frame (`image`) or a text element in a document (`text`).

## Results by Word

An OCR analysis task that analyzes an image or document (but not video) also produces a `WordResult` output track. To this track the OCR analysis engine adds a record for each word. The following XML shows an example record.

NOTE:

Text that is extracted from a text element in a document is not output to the `WordResult` track.

    <record>
      ...
      <trackname>ocr.WordResult</trackname>
      <OCRResult>
        <id>cdbca09b-c289-40af-b6e6-02427fafad91</id>
        <text>rover</text>
        <region>
          <left>240</left>
          <top>31</top>
          <width>194</width>
          <height>12</height>
        </region>
        <confidence>89</confidence>
        <angle>0</angle>
        <source>image</source>
      </OCRResult>
    </record>
