Near-infrared Coded Illumination-based Image Deblurring and Colorization

The handheld device-based biosensing for capturing nano-size bacteria is prone to suffering from motion blur. In this context, in this paper, we address an imaging method using near-infrared coded lights. Since the near-infrared illumination can cause the original color shifted in the captured image, we also discuss how to preserve the color information by capturing two consecutive images with complementarily designed illumination patterns. The proposed method with a coded near-infrared illumination can greatly improve the texture of the blurred images and aid in color restoration. We show the performance of the proposed method using a real dataset.
