We perform experiments to test basic human visual perception. In a typical experiment we ask our participants to perform simple discrimination tasks about carefully calibrated stimuli. For example: “Which of these images has higher contrast?”, “On which side did you see this target stimulus?”, “Are these dots on the same object?”, etc. These types of experiments allow extremely precise, quantitative measurements of human visual abilities, which fortunately are similar in different subjects.
Such measurements are the solid basis that allows us to build our complex theoretical models of human perception. These allow us to adjust all the technology surrounding us to work well for us: From the early insights into luminance and color processing that enable photography since the 19th century to the cameras, compression algorithms, and deep neural network and AI tools at work in your phone today. And perhaps more importantly precise psychophysical measurements can provide genuine quantitative insights into how the brain processes information.
