ABSTRACT
​

This paper presents the number of techniques for digital image processing which can be used to
detect damage or deformation shape on the external surface of container. These techniques include the
edge detect operators and the feature extraction methods. In this paper, we will show the effect of
Canny edge operator to detect the boundaries of extraordinary shapes on external surface of container.
Also, we present a new ideal of using Capsize-Gaussian-Function to detect edges of damage or
deformation. Lastly we analyze useful features to recognize these. However, the choice of these in real
systems needs to adjust several of parameters or choose a suitable operator and feature extraction
method, so it is far from being an easy task itself. And there is significant scope for improvement and
modernization port management technology.

Keywords: edge detection; Canny edge detector; Capsize-Gaussian-Function; damage or deformation.
