TooliFyra's Pencil Sketch tool converts your photos into realistic pencil drawings using edge detection and Gaussian blur techniques. Adjust the sketch intensity for light or bold effects.
The tool applies a Gaussian blur to the grayscale image, then uses the blur difference (similar to a high-pass filter) to extract edges. The result is inverted to create white paper with dark pencil-like lines.
The tool detects edges in the image and draws them as dark lines on a white background, similar to how a pencil creates marks on paper.
