ColorAdaptNet: A Novel Generative Model for Personalized Color Vision Deficiency Compensation

Individuals with Color Vision Deficiency (CVD) face difficulties in accurately distinguishing between colors due to reduced perceptual contrast. To address this issue, various image recoloring methods have been proposed. They perform recoloring either by using a CVD simulation model or by training deep learning models on images generated with such simulation models. These simulation models are based on assumed severity levels of color vision deficiency. However, in reality, there is currently no reliable way to measure the actual severity, and human color perception is highly complex and subjective. As a result, existing methods may not fully capture individual perceptual characteristics or user-specific preferences.To address this, we adopt an end-to-end learning approach based on each user's subjective evaluation. A major challenge with such approaches is the large amount of training data typically required. To overcome this limitation, we propose a new model and training strategy, along with a dataset specifically designed to capture key features of individual color perception. This enables us to train a personalized model for each user using only a very small amount of teacher data. In addition, we will release the source code and an anonymized dataset comprising data from 20 protan and deutan CVD users to support reproducibility and future research on personalized color compensation.
