The invention provides a figure
image processing method for preventing background deformation. The method comprises the following steps: 1, segmenting a figure image original image to obtain an original image masking image; 2, deforming the two images to obtain an original
image deformation image and an original image
mask deformation image; 3, filtering the figure image original
image layer by layer and generating a masking pattern to obtain an image
pyramid; carrying out expansion and distance transformation on the masking pattern; 4, calculating the gradient of an unknown region and carrying out SVD
decomposition; 5, performing neighbor search, cross search and limited
random search in sequence from the top layer of the
pyramid to obtain an
optimal matching block position; 6, filling the
optimal matching block position of each unknown pixel position; 7, repeating the steps 5 and 6, wherein the updated
pyramid bottom layer is a filling result graph; and 8, synthesizing the original
image deformation image, the original image
mask deformation image and the filling result image to obtain a character image with an undeformed background. According to the invention, the nature of theimage background can be maintained while the figure image is slimmed.
