Abstract:
Plenoptic camera is a new imaging device that can acquire 3-D content. In this camera, through a microlens array (MLA), real-world is captured from multiple angles. The MLA is placed next to the image sensing sensor, and the recorded image is called Lenslet (LL) image. Since a LL image consists of light rays from different angles, a LL image shall contain the 3-D information of the scene. Hence, it can be converted to multiview (MV) images that can be captured by an array of camera. There is an existing conversion tool for this process, namely RLC (Reference Lenslet Conversion).
This tool can convert from LL to MV. However, it cannot do the inverse conversion from MV to LL. In this project, we have following steps and targets:
- Study the RLC conversion tool and understand the process.
- Create an inverse RLC (invRLC) that can convert MV images to LL image.
Having both tools (RLC & invRLC), we aim to compress the content captured by plenoptic camera in two formats (LL and MV). In the last step, we use existing video coding tools to:
- Compare compression performance of LL image vs. MV images.
