LUMINANCE-PRESERVING AND TEMPORALLY STABLE DALTONIZATION - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240193825 titled 'LUMINANCE-PRESERVING AND TEMPORALLY STABLE DALTONIZATION
Simplified Explanation:
People with color vision deficiency struggle to differentiate between certain colors, such as reds and greens, leading to a loss of information. Image recoloring techniques, known as daltonization, aim to enhance the visual experience for individuals with color vision deficiency by preserving luminance in images.
Key Features and Innovation:
- The innovation focuses on preserving luminance in images to provide a consistent mapping for individuals with color vision deficiency.
- Conventional algorithms may cause temporal inconsistencies, such as flickering, when applied to a stream of images, but the luminance-preserving technique ensures temporal stability.
- By operating on pixels, the technique maintains a consistent mapping between colors, preventing flickering and other temporal issues.
Potential Applications: This technology can be applied in various fields such as graphic design, medical imaging, and digital art to enhance the visual experience for individuals with color vision deficiency.
Problems Solved: The technology addresses the challenge of preserving image appearance for individuals with color vision deficiency by maintaining luminance in images, thus improving their ability to distinguish between colors.
Benefits:
- Enhanced visual experience for individuals with color vision deficiency.
- Improved accessibility in various industries.
- Consistent mapping of colors in images, preventing temporal inconsistencies.
Commercial Applications: This technology can be utilized in industries such as graphic design, medical imaging software, and digital art platforms to cater to individuals with color vision deficiency and improve user experience.
Prior Art: Prior research in the field of image processing and color correction techniques may provide insights into similar technologies aimed at assisting individuals with color vision deficiency.
Frequently Updated Research: Stay updated on advancements in image processing techniques, color correction algorithms, and accessibility technologies to enhance the effectiveness of the luminance-preserving technique for individuals with color vision deficiency.
Questions about Color Vision Deficiency: 1. How does color vision deficiency impact daily activities for individuals? 2. What are the different types of color vision deficiency, and how do they affect color perception?
Original Abstract Submitted
it is difficult for people with color vision deficiency (cvd) to distinguish between certain colors, e.g., reds and greens may be indistinguishable, causing a loss of information. image recoloring, daltonization, techniques aim to improve the experience for people with cvd. preserving luminance between the original image as seen by a person with normal color vision and someone with a cvd assists in preserving image appearance. conventional algorithms attempt to daltonize images by exploiting the content of the image itself. while this is a suitable idea for an image in isolation, temporal inconsistencies (e.g., flickering) occur when applied to a stream of images, as a color c could be mapped to a color a in one frame and b in another. in contrast, the luminance-preserving technique operates on pixels and provides a consistent mapping and therefore is temporally stable.
