Deep learning architecture for image fusion
We are studying an efficient deep learning algorithm to fuse heterogeneous images. In particular, we are developing a deep fusion architecture to compute the cross-correlation for the efficient fusion between RGB and NIR images.

Knowledge distillation architecture
Knowledge distillation has been populary studied for network complexity reduction. We are studying an effective knowledge distillation architecture as a prior for image enhancement. Also, its usefulness is studied for image segmentation with small dataset.

Multi-spectral imaging for future cameras
We are studying a novel approach for high-quality image acquisition by integrating multi-spectral RGB and NIR bands.
It aims at enhancing visual quality (color constancy, low light enhancement, and denoising) and improving vision performances (NIR-to-RGB conversion) in the camera ISP, particularly for dark illumination environments and bad weather conditions.

Hyperspectral imaging
Hyperpsectral imaging has been popularly used for various remote sensing fields such as agriculture. We are researching on spectral imaging specially for plant growth estimation. In particular, a deep learning algorithm is studied for hyperspectral recovery from RGB images, which is quite challenging ill-posed problem.
Image decomposition under AC lights
Using the sinusoidal variation of AC lights, the camera image is decomposed into illumination and reflectance components, based on the Dichromatic and the Retinex models, and they are applied to image enhancement techniques for digital cameras such as color constancy, highlight removal, and multi-exposure fusion.

AI for fast and phytochemical-enhanced plant production
We have launched a new pioneering research project recently, which focues on ICT and plant science. It aims at understanding bio-feedback mechanisms between plant and its environments using AI and vision technologies.
Our ultimate goal is to develop a vision based AI system to grow plants fast.
These technologies are applied to both indoor plant factory and outdoor smart farm.
