What is grayscale morphology?

In grayscale morphology, a pixel is compared to those pixels surrounding it in order to keep the pixels whose values are the smallest (in the case of an erosion) or the largest (in the case of a dilation).

What is grayscale format?

In digital images, grayscale means that the value of each pixel represents only the intensity information of the light. Such images typically display only the darkest black to the brightest white. In other words, the image contains only black, white, and gray colors, in which gray has multiple levels.

Which morphological operation is used for smoothing an object in grayscale image?

The grayscale closing of an image involves performing a grayscale dilation, followed by grayscale erosion. The depth is the number of iterations of a particular operation. A basic morphological smoothing is an opening followed by a closing operation.

What is the purpose of grayscale in image processing?

Why is grayscale needed for image processing? It helps in simplifying algorithms and as well eliminates the complexities related to computational requirements. It makes room for easier learning for those who are new to image processing. This is because grayscale compressors an image to its barest minimum pixel.
