dc.description.abstract |
A combination of image processing algorithms can be used to detect and extract certain objects
from images. Image noise may obscure the objects in the images and must rst be removed using
image denoising and smoothing methods before the extraction of image objects can e ciently
be attempted. Contour detection algorithms can be used to identify and extract objects from
denoised images. The type of image, noise and noise intensity will determine the e ectiveness of
the denoising and smoothing methods. The combination of the aforementioned will also determine
the e ciency of the contour detection algorithms. In this dissertation we give some background on
basic mathematical morphology techniques and we see how those techniques are used in various
image smoothers and contour detection techniques. We develop our own smoother using some
ideas from other well-known smoothers and compare the performance of the di erent smoothing
methods. Various contour detection algorithms are investigated and we put the combination of the
smoothing methods and the contour detection algorithms to the test by comparing how e ciently
they detect and extract objects from images under various conditions. |
