Drcas: Deep Restoration Network For Hardware Based Compressive Acquisition Scheme
Pravir Singh Gupta, Xin Yuan, Gwan Choi · 2020
We propose a novel image acquisition scheme HCAS (Hardware based Compressed Acquisition Scheme) using hardware-based binning (downsampling), bit truncation and JPEG compression and develop a deep learning based reconstruction network DRCAS (Deep Restoration network for hardware based Compressed Acquisition Scheme) for images acquired using HCAS. DRCAS to our best knowledge is the first work proposed in the literature for the restoration of images acquired using acquisition scheme like HCAS. It is also superior in performance than state-of-the-art super resolution networks while being much smaller. We show that HCAS and DRCAS techniques will enable us to design much simpler and power efficient image acquisition pipelines.
