# Sample 3. Step 2: Visual analysis of the images and pre-recognition results

> Analyze invoice test images after pre-recognition to identify field names, column headings, and separators that can anchor FlexiLayout element searches.

Before creating elements, decide which objects on the document can be used to detect the data fields. These objects can be selected only from the graphical objects and/or paragraphs on the image that are reliably detected during the [pre-recognition](/flexi-capture/fls/batch/prerecognition) process.

Start pre-recognition by clicking Prerecognize. For more information, see [Tutorial 1, Step 4](/flexi-capture/fls/tutorial/step4).

Reviewing the pre-recognition results reveals that all the text objects corresponding to the names of the data fields (if a field has a name), names of columns, and horizontal separators have been reliably detected. These objects can be used to search for other objects on the images.

<Note>
  For more information on reviewing images and pre-recognition results, see [Tutorial 1, Step 5](/flexi-capture/fls/tutorial/step5) and [Step 6](/flexi-capture/fls/tutorial/step6).

Now you can start creating blocks and elements. To do this, activate the FlexiLayout window in the main window of ABBYY FlexiLayout Studio.
