Unsharp Mask is a sharpening technique that selectively enhances the edges of objects in an image, making them appear sharper and more defined. It is particularly effective for images with fine details, such as landscapes or architecture.

The "Radius" parameter in the High-Pass Filter determines the size of the sharpening kernel, which affects the width of the edges that are enhanced. A larger radius results in wider edges, while a smaller radius produces narrower edges.

The "Amount" parameter in Unsharp Mask controls the overall strength of the sharpening effect. Increasing the amount value intensifies the sharpening, making the edges more pronounced, while decreasing the amount value reduces the sharpening effect.

Median Filter is a sharpening technique that works by replacing each pixel in an image with the median value of its neighboring pixels. This helps to reduce noise and enhance the clarity of the image, particularly in areas with fine details.

The "Threshold" parameter in the High-Pass Filter specifies the threshold for edge detection. It determines the minimum difference in pixel values required for an edge to be considered significant and sharpened.

Gaussian Blur is a sharpening technique that applies a Gaussian blur filter to the image, followed by a subtraction of the blurred image from the original image. This technique is particularly effective for images with large, smooth areas, such as portraits or product shots, as it enhances edges without introducing excessive noise.

The "Radius" parameter in Gaussian Blur determines the size of the Gaussian blur kernel, which affects the smoothness of the blurred image. A larger radius results in a smoother blur, while a smaller radius produces a less pronounced blur.

High-Pass Filter is a sharpening technique that emphasizes the high-frequency components of an image, making edges and lines appear sharper and more defined. It is particularly effective for enhancing the clarity and sharpness of text and line art images.

The "Amount" parameter in High-Pass Filter controls the overall strength of the sharpening effect. Increasing the amount value intensifies the sharpening, making the edges more pronounced, while decreasing the amount value reduces the sharpening effect.

Median Filter is a sharpening technique that works by replacing each pixel in an image with the median value of its neighboring pixels. This helps to reduce noise and enhance the clarity of the image, particularly in areas with fine details, while preserving edges.

The "Radius" parameter in Median Filter determines the size of the median filter kernel, which affects the smoothness of the sharpened image. A larger radius results in a smoother image, while a smaller radius produces a less pronounced sharpening effect.

Unsharp Mask is a sharpening technique that selectively enhances the edges of objects in an image, making them appear sharper and more defined. It is particularly effective for images with a lot of fine details, such as landscapes or architecture.

The "Amount" parameter in Unsharp Mask controls the overall strength of the sharpening effect. Increasing the amount value intensifies the sharpening, making the edges more pronounced, while decreasing the amount value reduces the sharpening effect.
