论文摘要
在电影界，预计将观看相同的电影，从电影屏幕到手机的显示器大小不同。但是，视觉诱导，即场景区域的外观受周围环境影响的感知现象，对于在不同维度的两个显示上显示的相同图像的相同图像将有所不同。这对保存电影制片人的艺术意图提出了一个实用的挑战，因为它可能导致观看目的地之间的图像外观变化。在这项工作中，我们表明，基于有效表示原则的神经场模型能够预测诱导效应，以及如何通过正规化其相关能量功能，该模型仍然能够表示诱导，但现在是可逆的。由此，我们提出了一种以屏幕尺寸的相关方式预处理图像的方法，以便在视觉诱导方面的感知可以在不同大小的显示内保持恒定。通过心理物理实验在自然图像上的合成图像和定性示例中证明了该方法的潜力。
In the film industry, the same movie is expected to be watched on displays of vastly different sizes, from cinema screens to mobile phones. But visual induction, the perceptual phenomenon by which the appearance of a scene region is affected by its surroundings, will be different for the same image shown on two displays of different dimensions. This presents a practical challenge for the preservation of the artistic intentions of filmmakers, as it can lead to shifts in image appearance between viewing destinations. In this work we show that a neural field model based on the efficient representation principle is able to predict induction effects, and how by regularizing its associated energy functional the model is still able to represent induction but is now invertible. From this we propose a method to pre-process an image in a screen-size dependent way so that its perception, in terms of visual induction, may remain constant across displays of different size. The potential of the method is demonstrated through psychophysical experiments on synthetic images and qualitative examples on natural images.
