High Dynamic Range Imaging (HDRI) refere-se a um conjunto de técnicas que podem representar uma faixa dinâmica de luminância do mundo real. Conseqüentemente, a imagem HDR pode ser usada para medir a propriedade de refletância dos materiais. Para reproduzir a cor original dos materiais usando esta imagem HDR, é necessária a caracterização da imagem HDR. Neste estudo, propomos um novo método de caracterização HDRI sob uma condição de iluminação conhecida no nível HDR. O método proposto normaliza a imagem HDR usando a imagem HDR de uma luz e equilibra o tom usando a referência da cartela de cores. Demonstramos que nosso método supera o método anterior no nível LDR pela diferença média de cores e resultado de renderização BRDF. O método proposto proporciona uma reprodução muito melhor da cor original de um determinado material.

Abstract: High Dynamic Range Imaging (HDRI) refers to a set of techniques that can represent a dynamic range of real world luminance. Hence, the HDR image can be used to measure the reflectance property of materials. In order to reproduce the original color of materials using this HDR image, characterization of HDR imaging is needed. In this study, we propose a new HDRI characterization method under a known illumination condition at the HDR level. The proposed method normalizes the HDR image by using the HDR image of a light and balances the tone using the reference of the color chart. We demonstrate that our method outperforms the previous method at the LDR level by the average color difference and BRDF rendering result. The proposed method gives a much better reproduction of the original color of a given material.
