Kami mencadangkan skim pemetaan nada mengekalkan warna baharu. Pelbagai operasi pemetaan ton telah dikaji setakat ini, tetapi terdapat sangat sedikit kerja mengenai herotan warna yang disebabkan dalam pemetaan ton imej. Pertama, imej LDR yang dihasilkan daripada yang HDR dengan menggunakan operator pemetaan nada konvensional (TMO) ditunjukkan mempunyai beberapa herotan dalam nilai rona disebabkan oleh pemprosesan pengkuantitian keratan dan pembundaran. Seterusnya, kami mencadangkan kaedah baharu yang membolehkan imej LDR mempunyai nilai warna tepu maksimum yang sama seperti nilai warna HDR. Imej LDR yang dihasilkan oleh kaedah yang dicadangkan mempunyai kemerosotan rona yang lebih kecil daripada imej LDR yang dihasilkan oleh TMO konvensional. Selain itu, kaedah yang dicadangkan boleh digunakan untuk mana-mana TMO. Dalam eksperimen, kaedah yang dicadangkan ditunjukkan bukan sahaja untuk menghasilkan imej dengan degradasi rona kecil tetapi juga untuk mengekalkan kecerahan yang dipetakan dengan baik, dari segi tiga metrik objektif: TMQI, nilai rona dalam CIEDE2000, dan warna tepu maksimum pada pemalar- satah rona dalam ruang warna RGB.

Abstract: We propose a novel hue-preserving tone mapping scheme. Various tone mapping operations have been studied so far, but there are very few works on color distortion caused in image tone mapping. First, LDR images produced from HDR ones by using conventional tone mapping operators (TMOs) are pointed out to have some distortion in hue values due to clipping and rounding quantization processing. Next,we propose a novel method which allows LDR images to have the same maximally saturated color values as those of HDR ones. Generated LDR images by the proposed method have smaller hue degradation than LDR ones generated by conventional TMOs. Moreover, the proposed method is applicable to any TMOs. In an experiment, the proposed method is demonstrated not only to produce images with small hue degradation but also to maintain well-mapped luminance, in terms of three objective metrics: TMQI, hue value in CIEDE2000, and the maximally saturated color on the constant-hue plane in the RGB color space.
