Abstract
A method for exemplar-based inpainting using a Laplacian pyramid in a multi-scale space is provided, which is capable of reflecting structural features and texture features simultaneously every time inpainting is performed. The exemplar-based inpainting method using the Laplacian pyramid in the multi-scale space includes constructing a Laplacian pyramid image including a plurality of levels using an input image and performing inpainting reflecting the structural features of a low frequency region and the texture features of a high frequency region using the Laplacian pyramid image.
Claims8
A method for exemplar-based inpainting in a multi-scale space, the method comprising:
- constructing a Laplacian pyramid image including a plurality of levels using an input image;
- performing inpainting reflecting structural features of a low frequency region and texture features of a high frequency region using the Laplacian pyramid image,
- wherein the performing of inpainting comprises:
- performing inpainting with respect to a first recovery region selected in a to lowermost level image of the Laplacian pyramid image using a patch selected in an entire image region of the lowermost level;
- and
- performing inpainting using a patch region corresponding to the first recovery region in an upper level image of the lowermost level image.
An apparatus for exemplar-based inpainting in a multi-scale space, the apparatus comprising:
- an input unit to receive an input image;
- an image processing unit to compose a Laplacian pyramid image including a plurality of levels using the input image;
- an inpainting unit to perform inpainting reflecting structural features of a low frequency region and texture features of a high frequency region using the Laplacian pyramid image;
- and
- a patching unit to compose the Laplacian pyramid image gone through the inpainting,
- wherein the inpainting unit performs inpainting with respect to a first recovery region selected in a lowermost level image of the Laplacian pyramid image using a patch selected in an entire image region of the lowermost level, and performs inpainting using a patch region corresponding to the first recovery region in an upper level image of the lowermost level image.
