Light Field Photography for CGI/Live Action Video Integration
نویسندگان
چکیده
To separate out objects in a live action video sequence, an artist must step through the footage, frame by frame, and rotoscope out the occluding object from the background where a 3D computer generated graphic is to be inserted. This slow and expensive process can be remedied with the use of light field photography to capture depth information with every frame of film. These depth maps can be applied as a texture offset to the film in a 3D rendering program and virtual objects can be inserted into the scene at any particular depth, naturally occluding the background and being occluded by objects in the foreground, without any rotoscoping or manual editing. In this paper, we investigated two different methods of lightfield photography to replace

VLSI architecture for 4-D depth filtering
We propose the application of light field cameras and depth-selective 4-D IIR filtering to enable video surveillance, leveraging the post-capture depth-selective filtering enabled by computational photography. Novel ultralowcomplexity differential-form depth-selective 4-D IIR filter algorithms and their corresponding architectures are proposed for processing 4-D light fields. Practical results ...
متن کاملIntegration of Live Video and Computer Graphics for Video Effect Generation
We present the architecture of a system, based on a PC, covering real-time video processing by integration of live video and computer graphics. The video processing and integration are realized by generation and evaluation of an on-line MIPmap video texture. This new application of a known filtering technique for still textures in the field of live video processing permits an easy and high perf...

Background and Aim: Annually, a percentage of the profits from the sale of goods and services by producers are spent on costs of musculoskeletal disorders due to non-compliance with ergonomic conditions. These costs are not favorable for organizations and employees and in most cases, ergonomic risk factors affect the quality of life of employees. Methods: The present field study was conducted ...
متن کاملAction Change Detection in Video Based on HOG
Background and Objectives: Action recognition, as the processes of labeling an unknown action of a query video, is a challenging problem, due to the event complexity, variations in imaging conditions, and intra- and inter-individual action-variability. A number of solutions proposed to solve action recognition problem. Many of these frameworks suppose that each video sequence includes only one ...
