Engineering Contradiction Analysis
1Productivity
If conventional methods are used to generate edge-induced visual illusions, then the effect can be achieved on simple figures, but it requires significant time, effort, and technical skill, making it difficult to apply to complex images
Solution Approach 1:
The patent replaces manual mechanical drawing operations with an automated digital filter processing system. The edge-induced visual illusion generation is achieved through applying a two-dimensional digital filter with orientation selectivity to image data, extracting high-frequency components, and automatically generating the illusion effect without requiring manual technical skill.
Solution Approach 2:
The system performs self-service by automatically detecting edges and generating visual illusions through the digital filter processing pipeline. The multiresolution decomposition and high-frequency component extraction occur automatically without human intervention, allowing the system to serve itself in generating complex visual effects on any input image.
2Adaptability or versatility
If manual edge generation is used for each image, then edge-induced visual illusions can be created, but time and effort are required and design is restricted
Solution Approach 1:
The patent creates a universal system that can generate edge-induced visual illusions on any type of image (simple or complex) using the same digital filter processing methodology. The two-dimensional digital filter with orientation selectivity serves multiple functions: edge detection, high-frequency component extraction, and visual illusion generation, eliminating the need for different approaches for different image types.
Solution Approach 2:
The system changes parameters automatically through multiresolution decomposition and frequency domain processing. By transforming the image into frequency components and selectively processing high-frequency edges, the system adapts to different image complexities without requiring manual parameter adjustment or different processing methods.
3Manufacturing precision
If smooth brightness change is applied at edges, then the Craik-O'Brien-Cornsweet effect is achieved, but it is difficult to perform on complex figures
Solution Approach 1:
The patent replaces complex manual brightness adjustment operations with automated digital filter processing. The two-dimensional digital filter automatically performs the smooth brightness change required for the Craik-O'Brien-Cornsweet effect by processing high-frequency components in the frequency domain, eliminating the need for complex manual drawing and brightness control on each image.

AI summary
Provided are an edge-induced visual illusion generation apparatus, a method, a program, and a recording medium capable of being applied to any image, automatically generating an edge-induced visual illusion without complicated work, and improving contrast using the edge-induced visual illusion. A two-dimensional digital filter, which is a filter with no orientation or an even filter with orientation and is a filter that allows a band of a relatively high frequency to pass or a high pass filter, or is an orientation-selective wavelet frame or an orientation-selective filter bank that are a set of an approximation filter with no orientation and detail filters with orientations, is applied to image data, and a component of a relatively high frequency band or a high frequency component is extracted, and/or coloring is applied to an edge of the extracted band component or the high frequency component, thereby generating an edge-induced visual illusion image.
