Image Filter
Other types of image filters include:
- Gaussian Filter: Smooths and reduces noise based on Gaussian function.
- Laplacian Filter: Highlights regions of rapid intensity change, used for edge detection.
- Median Filter: Replaces each pixel with the median of its neighborhood, effective for “salt and pepper” noise.
- High-Pass Filter: Emphasizes edges and details.
- Low-Pass Filter: Blurs an image, allowing low-frequency components to pass.
- Sharpening Filter: Enhances edges and fine details.
- Prewitt Filter: Similar to Sobel, used for edge detection.
- Scharr Filter: Improved edge detection, similar to Sobel but with a different convolution kernel.
- Craigs Edge Detector: Detects edges based on intensity change rate.
- Bilateral Filter: Smoothes images while preserving edges.
