机器视觉的历史是一部摄影史。从早期开始，视觉“智能”机器的发展便与摄影密切相关。从最初的小型数据集到最近包含数百万图像的数据库，摄影在机器视觉发展中扮演了基础性的角色。摄影不仅是这一过程的伴侣；它还是机器视觉技术培养和进步的关键要素。

The history of machine vision is a photographic history. Since its early days, the evolution of visually “intelligent” machines has been closely intertwined with photography. From the first small datasets to recent databases consisting of millions of images, photography played a fundamental role in the development of machine vision. Photography has not just been a companion along this journey; it has been a pivotal element in the cultivation and advancement of machine vision technologies.

《有时你的眼睛看不见》摄影项目使用一种名为HOG（定向梯度直方图）的特征描述符，通过形似给定图像上光线分布的梯度，探究一种与摄影起源密切相关的技术的操作。

Using a feature descriptor called HOG (Histogram of Oriented Gradients) in the form of gradients that resemble the distribution of light on a given image, “Sometimes your eyes do not see” photographic project investigates the operational aspects of a technique that closely refers to the origin of photography.

卡洛·阿尔贝托·特雷卡尼在香港城市大学创意媒体学院获得了博士学位。目前，他是香港浸会大学人文与创意写作系的研究助理教授。他的工作探讨了视觉上“智能”机器的发展及其对我们看待世界方式的影响。作为一名艺术家，他的作品审视了图像的生产、复制、操纵、流通、感知与伪造。

Carloalberto Treccani received his PhD degree at the School of Creative Media, City University of Hong Kong. Currently he is currently a Research Assistant Professor at the Department of Humanities and Creative Writing at Hong Kong Baptist University. His work explores the development of visually ‘intelligent’ machines and their implications on the ways we see the world. As an artist, his work interrogates the production, reproduction, manipulation, circulation, perception, and falsification of images.
