Design and Implementation of 5-D IIR Depth Velocity Filters for Light Field Video Processing

Wijenayake, C; Liyanage, N; Edussooriya, C; Seatang, H; Agathoklis, P; Bruton, L [Article-Full-text]

The design and hardware implementation of a lowcomplexity signal processing algorithm is proposed for real-time depth-velocity filtering in 5-D light field videos (LFVs). The proposed design is based on a stable 5-D ...
Multi depth-velocity filters for enhancing multiple moving objects in 5-d light field videos

Liyanage, N; Jayaweera, SS; Edussooriya, CUS; Wijenayake, C; Madanayake, A; Agathoklis, P; Bruton, L; Ambikairajah, E [Conference-Full-text]

A moving object in a five-dimensional (5-D) light field video (LFV) can be selectively enhanced using the depth and the velocity of the object. In this paper, a 5-D depth-velocity (DV) filter is proposed to enhance ...
Multi-depth filtering and occlusion suppression in 4-D light fields: Algorithms and architectures

Liyanage, N; Wijenayake, C; Edussooriya, C; Madanayake, A; Agathoklis, P; Bruton, LT; Ambikairajah, E [Article-Full-text]

Low-complexity signal processing algorithms and reconfigurable digital hardware architectures are proposed for multi-depth filtering and occlusion suppression in 4-D light fields (LFs). The proposed multi-depth-pass (MDP) ...
Real-time light field denoising using a novel linear 4-D hyperfan filter

Premaratne, SU; Liyanage, N; Edussooriya, CUS; Wijenayake, C [Article-Full-text]

Four-dimensional (4-D) light fields (LFs) enable novel imaging technologies, which are traditionally based on two-dimensional images. In most of these applications, denoising of LFs is required as a preprocessing technique ...
Real-time light field signal processing using 4D/5D linear digital filter FPGA circuits

Edussooriya, CUS; Wijenayake, C; Madanayake, A; Liyanage, N; Premaratne, S; Vorhies, JT; Dansereau, DG; Agathoklis, P; Bruton, LT [Article-Full-text]

Light fields (LFs) and light field videos (LFVs) capture both angular and spatial variation of light rays emanating from scenes. This richness of information leads to novel applications such as post-capture refocusing, ...
