"E-fit" 电子面部识别技术

Liam

"E-fit" 的英文全称是 "Electronic Facial Identification Technique"，意为 "电子面部识别技术"。
这是执法机构用于在刑事调查中创建嫌疑人或相关人物的组合图像的方法，实质上是传统的合成素描的数字或电子版本。
当目击者或受害者提供嫌疑人的描述时，法医艺术家或专业软件程序可以利用这些描述来创建嫌疑人脸部的视觉表现。该过程涉及从数据库中选择不同的面部特征，例如眼睛、鼻子、嘴巴和头发。然后，将这些选定的特征组合在一起，以创建与嫌疑人描述相似的图像。
在没有明确的监控视频或嫌疑人照片的案件中，E-fits特别有用。通常会通过媒体渠道或执法机构的网站向公众发布这些图像，以寻求社区的帮助，以辨认出E-fits中所描绘的人物。这些图像有时可以帮助产生线索，并促使目击者或线人提供有价值的信息，以协助调查。

"E-fits" stands for "Electronic Facial Identification Technique." It is a method used by law enforcement agencies to create composite images of suspects or persons of interest in criminal investigations. E-fits are essentially digital or electronic versions of traditional composite sketches.
When witnesses or victims provide descriptions of suspects, a forensic artist or a specialized software program can use these descriptions to create a visual representation of the suspect's face. The process involves selecting different facial features, such as eyes, nose, mouth, and hair, from a database of facial features. These selected features are then combined to create an image that closely resembles the suspect's description.
E-fits are particularly useful in cases where there are no clear surveillance videos or photographs of the suspect. They are often released to the public through media channels or law enforcement websites to seek assistance from the community in identifying the person depicted in the e-fit. These images can sometimes help generate leads and prompt witnesses or informants to come forward with valuable information to aid in the investigation.

"E-fit™" 是与创建电子面部识别技术（E-fit）图像相关的特定软件或技术的商标。符号 "TM" 代表 "商标"，它用于指示 "E-fit" 这个术语是由特定公司或组织拥有的受保护商标。

当一家公司或实体开发出独特的产品、技术或品牌名称时，他们可以选择将其注册为商标来加以保护。这提供了法律保护，并且具有在特定产品或服务中使用该名称或标志的专属权利。"TM" 符号用于通知公众该术语是商标，即使注册过程仍在进行中或尚未完成。

一旦注册过程完成并获得批准，"TM" 符号可能会被替换为 "®" 符号，代表 "已注册商标"。"®" 符号表示该商标已经在相应的知识产权机构进行了正式注册，享有完全的法律保护。

对于 "E-fit™" 来说，很可能是某家公司或组织开发了一种专门用于创建 E-fit 图像的软件或技术，并将该术语注册为商标，以确立其所有权并在商业上保护其使用权。

"E-fit™" is a specific brand or trademark associated with a particular software or technology used for creating Electronic Facial Identification Technique (E-fit) images. The "TM" symbol stands for "Trademark," and it is used to indicate that the term "E-fit" is a protected trademark owned by a specific company or organization.

When a company or entity develops a unique product, technology, or brand name, they may choose to protect it by registering it as a trademark. This provides legal protection and exclusive rights to use the name or logo in connection with the specific product or service it represents. The "TM" symbol is used to notify the public that the term is claimed as a trademark, even if the registration process is still ongoing or not yet completed.

Once the registration process is finalized and approved, the "TM" symbol may be replaced with the ® symbol, which stands for "Registered Trademark." The ® symbol indicates that the trademark is officially registered with the appropriate intellectual property authorities and enjoys full legal protection.

In the case of "E-fit™," it is likely that a company or organization has developed a specialized software or technology for creating E-fit images and has trademarked the term to establish its ownership and protect its rights to use the term commercially.



比较  E-fit, identikit, photofit
E-fit（电子面部识别技术）、Identikit（身份组合图）和Photofit（照片组合图）都是执法机构用于创建嫌疑人或相关人物组合图像的方法。然而，它们在方法和技术上有所不同：
E-fit（电子面部识别技术）：
E-fit是一种现代的数字合成图像方法。
它涉及使用专业软件，允许法医艺术家从数据库中选择和组合不同的面部特征，以创建嫌疑人的图像。
由此产生的合成图通常比传统方法更加详细和逼真。
E-fit图像通常是以电子形式创建和传播，方便快速向公众传播，以寻求辨认帮助。
Identikit（身份组合图）：
Identikit是一种较早的手工制作合成图像方法。
它使用一系列预先绘制的面部特征，如眼睛、鼻子和嘴巴，存储在透明叠加层上。
法医艺术家或调查员将这些叠加层组合在一起，以匹配目击者对嫌疑人外貌的描述。
Identikit合成图可能会有效果，但与E-fit或其他数字方法相比可能缺乏细节和逼真度。
Photofit（照片组合图）：
Photofit是另一种较早的方法，它使用现有的各种人物面部照片。
这些照片被切割成片段，并手工组合在一起，以创建合成图像。
与Identikit类似，Photofit可能不像现代数字方法那样准确和详细。
由于使用现有照片的限制，Photofit可能无法完全捕捉目击者所描述的外貌。

总而言之，E-fit是一种数字化和先进的技术，能够产生详细和逼真的合成图像。Identikit和Photofit是较早的手工方法，它们使用预先绘制的特征或照片来创建合成图像，可能不如E-fit详细或准确。随着技术的进步，E-fit已成为现代刑事调查中创建合成图像的首选方法。

E-fit, Identikit, and Photofit are all methods used by law enforcement agencies to create composite images of suspects or persons of interest. However, they differ in their approaches and technologies:
E-fit (Electronic Facial Identification Technique):
E-fit is a modern and digital method of creating composite images.
It involves using specialized software that allows forensic artists to select and combine different facial features from a database to create the image of a suspect.
The resulting composite is usually more detailed and realistic compared to traditional methods.
E-fit images are often created and distributed electronically, enabling quick dissemination to the public for identification assistance.
Identikit (Identity Kit):
Identikit is an older and manual method of creating composite images.
It uses a collection of pre-drawn facial features, such as eyes, noses, and mouths, stored on transparent overlays.
A forensic artist or investigator assembles these overlays to match the witness's description of the suspect's appearance.
Identikit composites can be effective, but they may lack the level of detail and realism achieved by E-fit or other digital methods.
Photofit (Photographic Fit):
Photofit is another older method that uses pre-existing photographs of facial features from various individuals.
These photographs are cut into pieces and assembled manually to create a composite image.
Like Identikit, Photofit can be less accurate and detailed compared to modern digital methods.
Due to the limitations of using existing photographs, Photofit may not always capture the exact appearance described by witnesses.

In summary, E-fit is a digital and advanced technique that produces detailed and realistic composite images. Identikit and Photofit are older, manual methods that use pre-drawn features or photographs to create composite images, which may not be as detailed or accurate as E-fit. With advancements in technology, E-fit has become the preferred method for creating composite images in modern criminal investigations.
