Table Detection & Extraction From The Forms
- Detects all the tables in a form page.
- Create bounding boxes around it.
- Segment it out and extract the cells of the tables.
- Grayscale the image
- Binary Thresholding
- Get all the vertical lines using vertical kernel and
cv2.getStructuringElement
- Similarly, get all the horizontal lines using horizontal kernel and
cv2getStructuringElement
- Combine all the horizontal and vertical lines using
cv2.addWeighted
- Perform some morphological transformation like
cv2.erode to get crisp lines & for better results.
- Finding the contours and extracting out the rectangles/table cells.
