2. Morphological operations:csharp // Read an image Mat image = Cv2.ImRead("image.jpg", ImreadModes.Grayscale); // Create an input array from the image IInputArray inputArray = image.ToInputArray(); // Apply dilation to the input array Cv2.Dilate(inputArray, inputArray, new Mat(), iterations: 5); // Apply erosion to the input array Cv2.Erode(inputArray, inputArray, new Mat(), iterations: 5); ``` In both examples, the input array is created from a Mat instance, which is a matrix representation of an image. The input array is then passed as a parameter to the corresponding OpenCV functions. Overall, the IInputArray interface and GetInputArray method are crucial components of OpenCVSharp library, as they provide a convenient way to pass input arrays to various image processing functions.
