Scene completion of selfie photos based on image search = 이미지 검색을 활용한 자가촬영 사진의 배경 합성

We address scene completion of selfie photos through image search technique to expand the background of those photos. For searching descriptors efficiently, our system quantizes image descriptors for approximate nearest neighbor search, while finding similar images. Moreover, a query image is divided into a grid for weighting to utilize the spatial information of those descriptors. It allows searching similar images based on color and texture so that a result image can be completed with pasting similar images on the border of the query image by Poisson image editing iteratively. Therefore, our system can extrapolate the selfie photo by expanding the background regions where visual information does not exist. After determining the size of result image, our system also generates a creative image without specifying regions for image completion.
