Implementation of an integrated filter incorporating hole-filling and interpolation in tandem

Abstract

Conventionally, RGBD images are enhanced by implementing interpolation and hole-filling algorithm independently but it leads to a large amount of time-complexity along with low peak signal to noise ratio (PSNR). In this work, an integrated filter is proposed that implements hole-filling and interpolation concurrently. The performance is obtained via evaluation of PSNR and time-complexity. Moreover, a comparative analysis between the conventional and proposed scheme is propounded. It has been inferred that PSNR improves on using the proposed filter. Furthermore, the proposed filter reduces the timecomplexity noticeably by O(n2).
