Image Processing (IP) Through Erosion and Dilation Methods

Deepak Kulhare, M. D. Nirmal · 2013

The regulated morphological transforms still have some redundancies, though it takes more memory space and time for processing and searching the multimedia data. In this paper, the redundancies that are present in the regulated morphological transform are removed. To store the image in the for m of reduced regulated morphological transforms requires less memory space, less processing and searching time. Morphological processing is constructed with operations on sets of pixels. Binary morphology uses only set membership and is indifferent to the value, such as gray level or color, of a pixel. We will examine some basic set operations and their usefulness in image processing. A standard morphological operation is the reflection of all of the points in a set about the origin of the set. The origin of a set is not necessarily the origin of the base. Shown at the right is an image and its reflection about a point with the original image in green and the reflected image in white. Dilation and erosion are basic morphological processing operations. They are defined in terms of more elementary set operations, but are employed as the basic elements of many algorithms. Both dilation and erosion are produced by the interaction of a set called a structuring element with a set of pixels of interest in the image.
