Which of the following morphological operations is used to remove small objects from the foreground of a binary image?Select one:a. Dilationb. Erosionc. Closingd. Opening

Which of the following statements best describes the difference between opening and closing operations in image morphology?Select one:a. Opening removes small objects and fills in small holes, while closing fills in small holes and removes small gaps between objects.b. Opening reduces the size of objects, while closing increases their size.c. Opening reduces noise and sharpens the edges of objects, while closing smoothes the edges and fills in small holes.d. Opening removes small objects and gaps between objects, while closing fills in small holes and removes noise.

Dilation followed by erosion is called a ___ operation. It tends to increase the spatial extent of an object, while the ___ operation decreases its spatial extent.Select one:a. Subtractive operator, skeletonizingb. Thickening, Dilationc.  Skeletonizing, additive operatord. Closed, open

If we apply binary opening to the same large object twice using the same smallstructuring element, the effect, if any, of the second opening on the object is thatthe object:(a) is completely removed(b) is unchanged(c) becomes smaller(d) becomes larger(e) none of the above

n image morphology, a structuring element is a small binary image used for the morphological operations. Which of the following statements about structuring elements is correct?Select one:a. Structuring elements can have various shapes, such as squares, rectangles, circles, and lines.b. The structuring element must be a square matrix.c. The structuring element is applied to the image using convolution.d. The size of the structuring element must match the size of the objects to be removed.

Dilation followed by erosion is called a ___ operation. It tends to increase the spatial extent of an object, while the ___ operation decreases its spatial extent.
