在人工智能 (AI) 的现代时代,由于先进技术的发展,区分真实图像和计算机生成图像变得越来越具有挑战性。 人工智能可以在几秒钟内创建逼真的风景、肖像,甚至复杂的手部动作。 然而,经过仔细观察,存在一些差异,表明图像是人工智能生成的而不是真实的: 1. 不寻常的手和肢体结构:人工智能通常很难模仿人类四肢的复杂性。 仔细检查图像是否有手指排​​列、位置或大小的不规则之处。 不自然地拉长的手指、奇怪的关节角度和不正确的比例都是人工智能创造的表现。 2.缺乏细节准确性:由于人工智能依赖于模式识别,因此很难精确地呈现微小的细节。 如果阴影、纹理或背景成分等微小方面看起来模糊或合并,则图像可能是人造的。 3. 外观过于光滑:现实中的人通常会表现出一定程度的自然不规则性——皱纹、毛孔、不均匀的边缘等,而人工智能在创建图像时往往会忽略这些不规则性。 缺乏任何形式纹理的异常均匀的外观可以标志着人工智能的产生。 4.对齐问题:人工智能无法实现视觉元素的一致对齐,导致对象重叠或并置,违反基本物理定律。 仔细观察图像,尤其是具有多个组件的区域。 5. 小细节错误:仔细检查会发现看似普通的元素(例如耳环类型、眼镜部件或服装图案)中存在不一致或不匹配的特征。 请留意较小图像片段中的这些差异。 6. 难以辨认的文本或不合理的内容:人工智能生成的内容经常包含随机、扭曲或不可读的文本。 如果文本或标签出现混乱、损坏或无法辨认,则图像可能不真实。 此外,检查是否出现上下文不可信的情况或不合逻辑的场景,这很可能表明人工智能操纵。 通过学习识别这些微妙的差异,个人可以提高辨别真实表征和人工表征的能力,从而使自己掌握驾驭当今数字环境所必需的知识。

As artificial intelligence (AI) continues to develop, it’s getting harder and harder to tell the difference between real photographs and AI-generated images.

AI can create everything from stunning landscapes to lifelike portraits in a matter of moments—and at first glance, they may appear perfectly legitimate.

In this age of misinformation, how can you discern if the images you’re seeing are real or fabricated?

Fortunately, there are subtle clues that can help us tell the difference, including inconsistencies in texture, anomalies in human features, and garbled writing. By understanding these telltale signs, you can better navigate digital information and assess the authenticity of the images you encounter.

1. Unnatural Hands and Limbs

Hands and limbs are surprisingly complex structures, and AI often struggles to accurately replicate them. Look for extra, oddly shaped, or misaligned fingers. They may also be positioned in an unusual way or have improper dimensions.

In the above image, the children’s hands and feet look unnatural, with misshapen fingers and toes as well as misaligned sandal straps.

2. Discrepancies in Details

AI has difficulty rendering small details, so you might also see objects and elements being subtly merged together in unnatural ways. These imperfections occur because AI relies on pattern recognition, which can fail when handling intricate or nuanced details.

So if you’re uncertain if a crowd photo is legitimate, take a look at the details. For example, background faces are often blurred or have soft, poorly defined characteristics.

In this AI-generated image, the man in the water has a blurry face and fingerless hands, while the young man on shore has a transparent leg that appears to merge into the background.

3. Overly Perfect Skin

Having an overly smooth face with very little texture is a sign of an AI-generated photo. Its lack of genuine texture and flaws can almost make the individual look comical.

In the above images, the girl on the left has extremely smooth skin and hair that blends in with her collar. The boy to the right also has skin that is too smooth.

4. Misalignments

AI can struggle with alignments, resulting in a disjointed or incoherent appearance because elements don’t align properly.

Objects may overlap in unnatural ways that defy spatial coherence.

Zoom in to spot inconsistencies, such as in the above image, where the lines of the wicker cut through the picnic items. The texture lines on the woven picnic basket and tray are misaligned.

5. Inconsistencies and Asymmetries in Small Details

Inconsistencies in minor things, such as glasses with mismatched lenses or frames, should be easy to notice.

Though they appear genuine at first glance, the following AI-generated photos from ThisPersonDoesNotExist.com have flaws that may be seen with closer examination.

The woman in the left image is wearing two completely different earrings.

The center image is betrayed as AI-generated by the left corner, where the man’s shirt blends with the background.

In the image on the far right, the endpieces of the glasses are mismatched.

6. Garbled Writing

(AI-generated with Flux Pro)

AI-generated images often produce garbled or nonsensical text, with letters and words jumbled.

Take a close look at any writing or logos in the image to see if they are difficult to read or completely incoherent.

This image, produced by AI, depicts traffic on a crowded street. Upon closer inspection, you can see that the text on the roadside billboard is illegible.

7. Illogical Context
