Image Enlargement Based on Proportional Salient Feature

This paper proposes an image enlargement method that produces proportional salient content of image magnification. To obtain the proportional salient image content: first, we enlarge the source image to the high size of the target image using uniform enlarging. Second, we slice the image into sections from top to bottom following the minimum energy and detect the salient feature of the image. Third, we enlarge the slice of the image region that does not containthe salient feature of the image to the full size of the target image. The proposed method has been tested in several images, such as akiyo, butterfly, cameraman, canoe, dolphin, and parrot. The experimental results show that the proposed method results in a proportional content for image enlargement in the different ratios compared with the comparison method.
