Now you Can Digitally Restore Blurred Photos
Researchers at the Indian Institute of Technology (IIT) Madras have found a way to restore blurred photos. Dr. Rajagopalan is leading the IIT Madras image processing and computer vision lab. They are using artificial neural networks to restore the degraded images. Recently, the IIT team has published their work in IEEE Journal for selected topics in Signal Processing. It shows the methods which are developed by them. The method is to use a network of artificial neural groups to clean the images that are blurred due to raindrops, rain streaks, motion blur, etc. For their model, the team has used the available database of environmental agents. Dr. Rajagopalan described the study: At the time of research, it was difficult to identify the single neural network and clean the blurry parts on the images. Then they made the system in which the process took place in two different stages. The first step is called degradation localization, neural networks worked to identify and remove the degraded parts of the photos. The second step is to degrade Region-Guided restoration and to clear the image, the information that is provided in the first step is used. The main purpose is to guide the restoration process. One of the network layers in the first step performs a localization process and then it transfers the information collected to the “Main restore network”.
