Background:
- Color blindness significantly impacts daily activities and psychological well-being.
- Existing systems lack robust color recognition, especially under varying lighting conditions.
- Assisting color-blind individuals in making informed clothing choices is crucial.
Purpose of the Study:
- To develop an accurate color recognition and detection system for clothing images.
- To enhance system accuracy by employing advanced algorithms to mitigate lighting variations.
- To provide color matching recommendations for color-blind individuals.
Main Methods:
- Image processing techniques to extract RGB values and convert them to HSV color space.
- Integration of a machine learning model within a web application for color classification.
- Development of an interface to display predicted color names and matching color suggestions.
Main Results:
- Successfully retrieved and converted color values from images.
- Developed a functional web application capable of color prediction.
- Demonstrated the system's ability to suggest matching colors for user assistance.
Conclusions:
- The developed system offers a practical solution for color-blind individuals.
- Advanced algorithms improve color recognition accuracy despite lighting challenges.
- The system empowers color-blind users with better purchasing decisions and daily navigation.

546
Color perception begins in the retina, the light-sensitive layer at the back of the eye. Two main theories explain how colors are seen: the trichromatic theory and the opponent-process theory. The trichromatic theory, proposed by Thomas Young in 1802 and extended by Hermann von Helmholtz in 1852, suggests that color vision is based on three types of cone receptors in the retina. These cones are sensitive to different but overlapping ranges of wavelengths corresponding to red, blue, and green.

01:22Photoreceptors and Visual Pathways
5.9K
At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category,...

01:12Perceptual Constancy
371
Perceptual constancy is the ability to recognize that objects remain consistent and unchanged even when their appearance varies due to changes in sensory input. There are four main types of perceptual constancy: size constancy, shape constancy, color constancy, and brightness constancy.
Size constancy is the recognition that an object remains the same size, even when its image on the retina changes. For instance, a bus is perceived to be large enough to carry people, even if it looks tiny from...

01:12Visual Agnosia
184
Visual agnosia is a condition characterized by the inability to recognize visually presented objects despite having normal vision. For instance, a person with visual agnosia can describe the shape and color of an object but cannot identify or name it. This impairment does not affect their visual field, acuity, color vision, brightness discrimination, language, or memory. An example of this condition in a social setting is someone at a dinner party asking for "that silver thing with a round...

01:19Pigmentation
2.3K
The color of the skin is influenced by a number of pigments, including melanin, carotene, and hemoglobin. Recall that melanin is produced by cells called melanocytes, which are found scattered throughout the stratum basale of the epidermis. The melanin is transferred to the keratinocytes via melanosomes.
Melanin occurs in two primary forms: eumelanin that provides black and brown pigment and pheomelanin that provides red color. Dark-skinned individuals produce more melanin than those with pale...

01:24Prosopagnosia
152
Prosopagnosia, also known as face blindness, is the inability to recognize faces. In severe cases, individuals with prosopagnosia may not recognize close family members, including parents and spouses, by their faces. For instance, someone with prosopagnosia might walk past their child in a crowd, only realizing their mistake upon noticing their child's distinctive backpack or favorite jacket. Prosopagnosia specifically impairs facial recognition, while the recognition of other objects or...
