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

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

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.

What is an opening?Group of answer choicesb. An opening is an opportunity to insert new information where there is a gap.a. An opening is the first sentence of an introduction.d. An opening is white space left between two portions of a document.c. An opening is usually a sentence or small paragraph that identifies the subject and purpose of the section.

Each of the following programs opens a file for reading and returns the first line. Which of the two properly closes the file?# Program A:1# Program A2def get_status(file):3  return open(file).readline()# Program B:1# Program B2def get_status(file):3  with open(file) as fp:4    return fp.readline() Program B is safer as it always closes the file on return. Program A is safer as the file close happens implicitly when the temporary file object goes out of scope.Both are identical and correct. Both are incorrect as there is no explicit close anywhere.
