Descriptif détaillé de la thèse / PhD description
Considering the design and fabrication of new material surfaces having a natural or complex aspect wood, granite, leather…), it is a challenge to visually reproduce the same color aspect. To avoid any confusion, we are interested in texture perceived by human, also known as non-uniform and homogeneous aspect [1]. The question of this project is: How can we measure the distance between two textures to improve the quality control?
The first objective is to assess the Just Noticeable Difference for non-uniform patches starting from color Gaussian distributions. The second one is to create a distance linked to human perception of nonuniform aspect scaling.
