CGVC 2018 Talk - A Deep Learning Approach to No-Reference Image Quality Assessment For Monte Carlo Rendered Images

A video of my talk taken by my co-author Prof. Mark Jones on our paper "A Deep Learning Approach to No-Reference Image Quality Assessment For Monte Carlo Rendered Images" published at CGVC 2018.

In Full-Reference Image Quality Assessment (FR-IQA) images are compared with ground truth images that are known to be of high visual quality. These metrics are utilized in order to rank algorithms under test on their image quality performance. Throughout the progress of Monte Carlo rendering processes we often wish to determine whether images being rendered are of sufficient visual quality, without the availability of a ground truth image. In such cases FR-IQA metrics are not applicable and we instead must utilise No-Reference Image Quality Assessment (NR-IQA) measures to make predictions about the perceived quality of unconverged images. In this work we propose a deep learning approach to NR-IQA, trained specifically on noise from Monte Carlo rendering processes, which significantly outperforms existing NR-IQA methods and can produce quality predictions consistent with FR-IQA measures that have access to ground truth images.
