Erosion¶. Morphological erosion sets a pixel at (i, j) to the minimum over all pixels in the neighborhood centered at (i, j).The structuring element, selem, passed to erosion is a boolean array that describes this neighborhood. Below, we use disk to create a circular structuring element, which we use for most of the following examples.

2008-08-15 · This study examines the alongshore variation in dune morphology along a 11 km stretch of Santa Rosa Island in northwest Florida and relates the variation in morphology to the response of the island during Hurricane Ivan and historic and storm-related rates of shoreline erosion. The morphology of the foredune and backbarrier dunes was characterized before and after Hurricane Ivan using Empirical Orthogonal Function (EOF) analysis and related through Canonical Correlation Analysis The intersection of the two erosion operations would produce just one pixel at the position of the centre of the 3x3 square in A, which is just what we want. If had contained more than one square, the final result would have been single pixels at the positions of the centres of each. This combination of erosions forms the hit-or-miss transform.

▫ Hit-miss filter. ▫ Binary dilation and erosion.

Note that you need to provide at least two items, the morphology 'method', telling the operator type of operation you want to apply to the image, and a 'kernel' specifying what 'neighbouring' pixels should effect the final result.Both are equally important and both can have far reaching consequences. You can get a list of the methods that are available using "-list morphology".

The second is a (usually small) set of coordinate points known as a structuring element(also known as a kernel). It is this structuring element that determines the precise effect of the erosion on the input image.

The first problem is I cannot use 0 as background as usualy I do. So I biased my values.

Properties of dilation and erosion. Commutative: Conduct the most advanced studies of real-life engineering problems such as the morphological optimisation of port layouts, impact of shore protection schemes, stability of tidal inlets, sedimentation in dredged channels and port entrances, erosion over buried pipelines, as well as river and estuarine morphology with this unparalleled duo. Erosion of hard‐rock coastal cliffs is understood to be caused by a combination of both marine and sub‐aerial processes.

Erosion and Dilation. These two functions are fundamental for almost all morphology operations. Erosion is a function that basically removes (sets the value to 0) pixels from the border of particles or objects. If particles are very small, they may be removed totally.
