  There is an increasing requirement for efficient image retargeting techniques
to adapt the content to various forms of digital media. With rapid growth of
mobile communications and dynamic web page layouts, one often needs to resize
the media content to adapt to the desired display sizes. For various layouts of
web pages and typically small sizes of handheld portable devices, the
importance in the original image content gets obfuscated after resizing it with
the approach of uniform scaling. Thus, there occurs a need for resizing the
images in a content aware manner which can automatically discard irrelevant
information from the image and present the salient features with more
magnitude. There have been proposed some image retargeting techniques keeping
in mind the content awareness of the input image. However, these techniques
fail to prove globally effective for various kinds of images and desired sizes.
The major problem is the inefficiency of these algorithms to process these
images with minimal visual distortion while also retaining the meaning conveyed
from the image. In this dissertation, we present a novel perspective for
content aware image retargeting, which is well implementable in real time. We
introduce a novel method of analysing semantic information within the input
image while also maintaining the important and visually significant features.
We present the various nuances of our algorithm mathematically and logically,
and show that the results prove better than the state-of-the-art techniques.
