How to fill out prewitt sobel and scharr

How to fill out prewitt sobel and scharr?

1. Understand the purpose: Prewitt, Sobel, and Scharr are different algorithms used in image processing for edge detection. Before filling out these algorithms, it's essential to understand their purpose and how they work.
2. Choose a programming language: Prewitt, Sobel, and Scharr can be implemented using different programming languages such as Python, MATLAB, or C++. Choose a programming language that you are comfortable with and have the necessary libraries or functions to implement these algorithms.
3. Initialize the necessary variables and import libraries: Start by initializing the variables required for the algorithms such as image arrays, kernel matrices, and result arrays. Import the relevant libraries or functions for image manipulation and filtering.
4. Load and preprocess the image: Read the image file or capture it using a camera. Preprocess the image by converting it into grayscale since edge detection algorithms work best with grayscale images. You can also apply smoothing filters like Gaussian blur to reduce noise before applying the edge detection algorithms.
5. Apply the Prewitt algorithm: Prewitt algorithm uses two 3x3 kernels to convolve with the image to detect horizontal and vertical edges. Apply the Prewitt algorithm to the preprocessed image and store the resulting edge map.
6. Apply the Sobel algorithm: The Sobel algorithm is similar to Prewitt but uses 3x3 kernels with different coefficients to compute the gradient magnitude and orientation. Apply the Sobel algorithm to the preprocessed image and save the resulting edge map.
7. Apply the Scharr algorithm: Scharr algorithm is an improvement over the Sobel algorithm as it provides better edge detection in terms of accuracy and speed. It also uses 3x3 kernels but with different coefficients. Apply the Scharr algorithm to the preprocessed image and store the resulting edge map.
8. Display or save the output: Once the edge detection algorithms are applied, display or save the resulting edge maps for further analysis or visualization.
