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.

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.

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 statements about structs is not true:Group of answer choicesThe components in a struct can reuse component names used in other structs, provided there are no duplicate names at the same level in any particular structStructs can only contain named variables, and cannot include arraysIf an array of structs is declared, each element in that array will have all of the properties of the struct type that is the array's base typeWhole structs can be assigned via the assignment operator A=B, provided that A and B are of the same typeIf an array of structs is declared, and a integer buddy variable is then required, the buddy variable can be combined with the array as part of a larger "everything together" struct that is a single compound object

Which of the following structure(s) is/are correct?  Tick all correct answer(s)  No partial marks and no negative marks.Select one or more:struct aa {     int a;     float b; };struct aa {     int a;     float b;     struct aa var; };struct aa {     int a;     float b;     struct aa *var; };
