    Drawing. Seeing.

    Drawing an object and naming it engages the brain in similar ways, according to research recently published in JNeurosci. The finding demonstrates the importance of the visual processing system for producing drawings of an object. In a study by Fan et al., healthy adults performed two tasks while the researchers recorded brain activity using functional […]

    Not seeing the tree… 

    Researchers have shown how it is possible that objects stand out less when they are surrounded by similar objects. This surroundings-suppressing effect is caused by feedback from higher visual brain areas. The results of this research are important for a better understanding of the way in which the brain transforms incoming light into a cohesive […]

    Blurry images…

    The ghost imaging technique forms an image by correlating a beam that interacts with the object and a reference beam that does not. Individually, the beams don’t carry any meaningful information about the object. The imaging technique works with visible light, x-rays and other parts of the electromagnetic spectrum and, when the structured light beams […]

    Seeing what cannot be seen…

    Identifying geological features in a densely vegetated, steep, and rough terrain can be almost impossible. Imagery like LiDAR can help researchers see through the tree cover, but subtle landforms can often be missed by the human eye. A team of scientists has tapped into the power of machine learning to identify hidden geologic features. Specifically, […]

    Seeing better. And better. And better. Until we see nothing at all…

    A few years ago, a team of scientists at EPFL’s Laboratory of Nanoscale Biology, headed by Aleksandra Radenovic in the School of Engineering, developed an algorithm that can estimate a microscope’s resolution in just a few seconds based on a single image. The algorithm’s result indicates how closely a microscope is operating to its full […]
