What is dilation In image processing?

Dilation adds pixels to the boundaries of objects in an image, while erosion removes pixels on object boundaries. The number of pixels added or removed from the objects in an image depends on the size and shape of the structuring element used to process the image.

How is dilation performed?

The dilation operator takes two pieces of data as inputs. The first is the image which is to be dilated. 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 dilation on the input image.

What is dilation in computer vision?

Dilation is a morphological operation used to enhance the features of an image. Dilation as a function requires two inputs, an image to be dilated, and a two dimensional structuring element. Dilation has many applications, but is most commonly used to exaggerate features in an image that would otherwise be missed.

How do you dilate a binary image?

J = imdilate( I , SE ) dilates the grayscale, binary, or packed binary image I using the structuring element SE . J = imdilate( I , nhood ) dilates the image I , where nhood is a matrix of 0 s and 1 s that specifies the structuring element neighborhood. This syntax is equivalent to imdilate(I, strel (nhood)) .

What is application of dilation?

Originally developed for binary images, it has been expanded first to grayscale images, and then to complete lattices. The dilation operation usually uses a structuring element for probing and expanding the shapes contained in the input image.

What is the difference between dilatation and dilation?
