What is erosion in morphological operation?

The most basic morphological operations are dilation and erosion. Dilation adds pixels to the boundaries of objects in an image, while erosion removes pixels on object boundaries.

What is morphological operations in image processing?

Morphological Operations is a broad set of image processing operations that process digital images based on their shapes. In a morphological operation, each image pixel is corresponding to the value of other pixel in its neighborhood.

What is erosion and dilation in Opencv?

Erosion basically strips out the outermost layer of pixels in a structure, where as dilation adds an extra layer of pixels on a structure.

What does erosion do in image processing?

Erosion removes pixels on object boundaries. In other words, it shrinks the foreground objects. Enlarge foreground holes. Like in Image Processing Kernels, a larger size of the Structure Element, the effect of Erosion increase.
