Image Enlargement Based on Proportional Salient Feature

Abstract

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.
