1. Introduction Is the color of the left ring lighter than the right ring in Figure 1b? Is the color inside each block in Figure 1c light on the left and dark on the right? Actually, Figure 1b is the result of splitting Figure 1a down the middle without changing the color of the image. In Figure 1c, each color patch is monochromatic. These captivating visual illusions can be elucidated through the phenomenon of lateral inhibition.
Digital cameras use detector arrays with regular geometry for optical sampling. Though regular arrangement was demonstrated to be optimal for two-dimensional sampling, it causes aliasing at high frequencies exceeding its Nyquist limit. Here, we proposed a randomization procedure to generate 2D hyperuniform patterns that can be used to suppress aliasing in image retrieval.
In contrast to conventional multipixel cameras, single-pixel cameras capture images using a single detector that measures the correlations between the scene and a set of patterns. However, these systems typically exhibit low frame rates, because to fully sample a scene in this way requires at least the same number of correlation measurements as the number of pixels in the reconstructed image.
