Prompt

Transform this image into a Gabor Filter Bank visualization using aligned translucent response layers for different angles and texture scales. Highlight horizontal, vertical, and diagonal structures in distinct colors, with fine striped responses and broader luminous bands against subdued dark surfaces. Keep the original subject and composition.

Identify

You see an image broken down into distinct layers, where lines and textures of specific angles and thicknesses are highlighted.

Principle

The algorithm applies a series of mathematical masks called Gabor filters. Each filter targets specific spatial frequencies1 and distinct orientations2.

Try it out

Change the angles and wavelengths to see different textures pop out from the background.

Classification

Calculated image processing result.
