  • Method and system for removing scene text from images
    Patent number: 11423597
    Abstract: Methods of removing text from digital video or still images are disclosed. An image processing system receives an input image set defining a region of interest (ROI) that contains text. The system determines an input background color for the ROI. The system applies a text infilling function to remove text from the ROI to yield a preliminary output image set. The system may determine a residual corrective signal that corresponds to a measurement of background color error between the input set and the preliminary output set. The system may apply the residual corrective signal to the ROI in the preliminary output set to yield a final output set that does not contain the text. Alternatively, the system may remove background from the ROI of the input set before text infilling, then return background to the ROI after the text infilling.
