Video Generation Using Moving Stripes for Stationary Object Motion

Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing methods to provide motion impression to stationary objects either alter the luminance of the object or require an outline, which can degrade the appearance of the object.

Innovation Solution

Generate a video with a stationary object region and a background region containing a striped-texture region adjacent to the object's outline, where the striped texture moves orthogonal to the outline, providing illusory motion without changing the object's luminance or color.

1Illumination intensity

If grayscale motion information is projected onto a stationary object, then motion impression is provided to the object, but the luminance of the object changes from its original luminance

Engineering Contradiction:

ImproveluminanceVSAvoidappearance quality

Core Design Contradiction:

Illumination intensityVSEase of manufacture

Solution Approach 1:

The video is segmented into a stationary object region and a background region with striped texture. The striped texture is applied only to the background, not the object itself, allowing motion perception without altering the object's luminance.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different regions of the video have different properties: the object region maintains original luminance while the background region contains moving striped texture. This local differentiation allows motion illusion without compromising object appearance.

Inventive Principle:

Principle #3Local quality

2Ease of operation

If an outline line is provided to a stationary object to create motion perception, then motion impression is provided, but the appearance of the object degrades

Engineering Contradiction:

Improvemotion perceptionVSAvoidappearance

Core Design Contradiction:

Ease of operationVSShape

Solution Approach 1:

The outline line is extracted from the object and applied only to the background region. This separates the motion-inducing element from the object itself, allowing motion perception without adding visual elements that would degrade the object's appearance.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The striped texture in the background acts as an intermediary that creates motion perception for the stationary object without directly modifying the object. The moving background patterns provide motion cues that make the stationary object appear to move.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A video including a stationary object region and a background region other than the stationary object region is generated. The background region includes a striped-texture region adjacent to the outline of the stationary object region, and a striped texture having a striped luminance pattern moves in a direction having a component orthogonal to the outline in the striped-texture region.
