Abstract:
Noise is often present in digital images during the steps of image acquisition, coding, transmission and
processing. Low-light is also a challenging area for image processing, either for enhanced visibility and
efficiency, or for application-oriented tasks such as detection. In image processing, denoising images and
object detection is a fundamental issue. In this paper we will try to give an overview on how we are going
to do with the help of Non local means denoising algorithm and image sharpening for edge defining more
significantly.
