What is morphological gradient in image processing?
In mathematical morphology and digital image processing, a morphological gradient is the difference between the dilation and the erosion of a given image. It is an image where each pixel value (typically non-negative) indicates the contrast intensity in the close neighborhood of that pixel.
How do you find the morphological gradient?
Morphological Gradient is the operation that is equal to the difference between dilation and erosion of an image. Each pixel value in the resulting image indicates the contrast intensity in the nearby pixels. This is used in edge detection, segmentation and to find the outline of an object.
What is the advantage of morphology operation dilation over low pass filtering in binary images?
Dilation: Joining broken segments
One immediate advantage of the morphological approach over lowpass filtering is that the morphological method resulted directly in a binary image, while lowpass filtering started with producing gray-scale image.
What is morphological smoothing?
Morphological Smoothing. • A basic morphological smoothing is an opening followed by a closing operation. – It removes both bright and dark artifacts of noise.
