WebOct 11, 2024 · In this paper, we present a method for highlight removal in facial images. In contrast to previous works relying on physical models such as dichromatic reflection models, we adopt the structure of conditional generative adversarial network (CGAN) to generate highlight-free images. By taking the facial images with specular highlight as the ... WebDichroic filter. A dichroic filter, thin-film filter, or interference filter is a color filter used to selectively pass light of a small range of colors while reflecting other colors. By comparison, dichroic mirrors and dichroic reflectors tend to be characterized by the colors of light that they reflect, rather than the colors they pass.

In Shafer’s dichromatic reflection model, scene radiance has two components: λ is the wavelength, cb is the body (diffuse) reflected component, cs is the surface (interface) (specular) reflected component, mb and ms are scale factors depending on illumination, view directions and surface orientation. WebMay 10, 2024 · In Shafer’s dichromatic reflection model, [1] scene radiance has two components: L ( λ) = m b c b ( λ) + m s c s ( λ) λ is the wavelength, cb is the body ( diffuse) reflected component, cs is the surface (interface) ( specular) reflected component, mb and ms are scale factors depending on illumination, view directions and surface orientation.
WebAbstract. A feature-based technique for separating specular and diffuse components of a single image is presented. In the proposed approach, Shafer’s dichromatic reflection model is utilized, which assumed a light reflected from a surface point is linearly composed of diffuse and specular reflections. The major idea behind the proposed method ... WebThe dichromatic reflection was proposed to use the spectral projection in the color space with the diffuse and specular reflection colors as the boundary. However, this method required that the pixel on single surface should be in the parallelogram [9] .
