This page shows output results of an FPGA pipeline dedicated to MPA (Micro Polarizer Array) imaging. Results were obtained using a Zynq FPGA (Zedboard) and the FPGA-in-the-loop hardware verification tool.

1. Raw video

Description: raw output video from an MPA imager (PolarCam V from 4D Technology). Scene is composed of pieces of linear polarizers crossing and moved by hand in front of the camera. At the bottom, we can see the delimitation between the filter covering the sensor and the bare sensor (due to some manufacturing problems).

2. Recovering the full spatial resolution for polarimetric video by using 3x3 interpolation kernel filters.

Description: the four polarization states (I0, I45, I90 and I135) are recoverred from the raw video data.
