Under-display Camera Image Restoration

Under-display Camera (UDC) is a new imaging system that mounts the camera under the display. It allows a larger screen-to-body ratio and better eye tracking; however, the camera’s image quality is seriously degraded due to the decrease in light transmittance and diffraction effect. There have been studies on image restoration models, which cannot be applied to real-world applications on mobile devices due to the lack of restoration speed and quality. We are preparing real-world datasets for UDC image restoration and developing a real-time image restoration DNN model by overcoming the limitations of mobile architectures. We exploit methods such as model quantization and vectorization.
