Improved Exemplar based Image Inpainting for Partial Instance Occlusion Handling with K-means Clustering and YCbCr Color Space

Abstract

The images acquired in real time outdoor environment are often subject to uneven illumination conditions, cloudy weather, lighting conditions. The instances of partial occlusions deteriorate the background modeling of such scenes. Varying illumination outdoor scene set of images with partial occlusions are addressed through this investigative work. There is a need for a restoration method that finds improved subjective perception and execution time. The proposed work focuses on novel amended exemplar model to improve the subjective perception. The exemplar inpainting method is improved through the color quantization with K-means clustering approach in YCbCr color space. Experimental validations and proposed method results show better improvement in qualitative and objective measures than existing methods. The average "Peak Signal to Noise Ratio (PSNR)" as 28.2869 and "Structural SIMilarity index (SSIM)" as 0.9759 of the proposed method has shown better results respectively both visually and with a tradeoff in time.

“…Tablo 2'de incelenen çalışmalar ve bu çalışmalarda kullanılan yöntemler, renk uzayları, çalışmaların literatüre katkıları ve çalışmaların kısıtları bulunmaktadır. Önerilen yöntem için ortalama 28.2869 PSNR ve 0.9759 SSIM değerlerine ulaştıklarını belirtmişlerdir [49]. İncelenen diğer çalışmalardan farklı olarak Yaghmaee ve Peyvandi SVD tabanlı yapı ve doku bilgilerinin kullanıldığı bir görüntü iç boyama yöntemi önermişlerdir.…”
