Prompt

Apply Optical Flow Vectors as a technical overlay of small, high-contrast arrows anchored to visible image features. Use coherent arrow directions and lengths to suggest estimated displacement between slightly shifted frames, leaving low-detail areas sparse. Keep the underlying photograph legible and naturally colored. Preserve the original subject and composition.

Paste it into LetzAI with your own image to apply the effect ↗

Identify

Arrows indicate estimated image movement.

Principle

Lucas-Kanade tracking1 estimates the shift between two synthetically shifted frames2.

Try it out

Compare global and local movements.

Classification

Calculated image processing result.
