Locally Adaptive Demosaicing Technique for Security Images Based upon Region-of-Interest Analysis

Popis výsledku v původním jazyce

Demosaicing approach based upon ROI analysis. The question of if only the quality of areas where human gazes are crucial for quality of identification is solved. Two FDMs were constructed on the basis of the ground through visual attention data. Two security scenes containing traffic signs were used as testing images. SSIM and VIF with subjective testing were used for evaluation of reconstruction quality. The results tackle the questions - if quality of identification mainly depends on the quality of the areas where human eye is attracted, areas of interest, and whether the quality of the remaining part of image perceived by peripheral vision is crucial for quality of identification. Furthermore, the results show that embedding the information relatingto these visual fixation patterns into demosaicing procedure can preserve the perceived image quality and quality of identification, while the computational complexity of proposed approach can be low.
