Superresolution with Plenoptic 2.0 Cameras

Abstract

We demonstrate working superresolution with Plenoptic 2.0 camera without need for traditional image registration in software. This paper describes our method, based only on the camera geometry and microlens parameters.

Superresolution with the focused plenoptic camera

“…In another experiment we worked with the raw data from the superresolution camera of Georgiev and Lumsdaine, 10 as shown in Figure 15 (data used with permission). Figure 16 shows the rendering results.…”

Towards Motion Aware Light Field Video for Dynamic Scenes

“…LF capture: Existing LF cameras can be divided into two main categories: (a) single shot [24,13,30,20,27,12,22], and (b) multiple shot [18,23,3]. Most single shot light field cameras multiplex the 4-D LF onto the 2D sensor, losing spatial resolution to capture the angular information in the LF.…”

“…Most single shot light field cameras multiplex the 4-D LF onto the 2D sensor, losing spatial resolution to capture the angular information in the LF. Such cameras employ either a lenslet array close to the sensor [24,12], a mask close to the sensor [30] or an array of lens/prism outside the main lens [13]. Recently, [22] extended the mask based method of [30] to exploit sparse representations in order to recover full resolution LF.…”

“…Recently, several LF super-resolution algorithms have been proposed to recover the lost resolution [12,4]. The Plenoptic2.0 camera [12] recovers the lost resolution by placing the microlens array at a different location compared to the original design [24].…”

“…Thus, it is clear that there exists a resolution barrier ( Figure 1) for capturing high resolution LF video. Recently, a series of approaches such as Plenoptic 2.0 camera [12] and LF super-resolution techniques [4] have begun breaking this resolution barrier.
