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

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 time-complexity noticeably by O(n2).
