Description of the Special Effects & Virtual Human

November 22 00:09 2022

The world will gradually become virtualised in the future. Virtual generation technology can automatically generate personalised facial expression substrates from a single selfie image alone.Which is widely used in scenarios involving character modelling such as social networking, live streaming and gaming, which helps developers and users to build 3D virtual images with high similarity and aesthetics quickly and at low cost. The platform has both face expression and voice driven capabilities, allowing developers to quickly build site-wide applications.

I. Product design

A comprehensive range of image capabilities can be quickly acquired by integrating virtual images.Such as personalizing virtual men for users on the page, or socializing and interacting in real time with facially driven expressions that follow the virtual image, etc. From a technical point of view, the virtual image consists of three key components: Generation, Driving and Rendering.

(i) Special effects on the face

1. Accurate identification

Millisecond keypoint detection of faces such as eye, mouth and nose contours, supporting keypoint detection of faces with different accuracies, and various extended applications of faces based on this technology.

2. Dynamic stickers

Based on face keypoint technology, the 2D stickers fit perfectly on the face and support the detection of multiple faces and the addition of punctuation and effects with guaranteed performance. The platform’s sticker library provides users with hundreds of resources to choose from. 

3.Face deformation

Based on the face keypoint technology, we offer our customers a wide range of different face morphing effects (magic mirror), including square face and papaya face.

4.Hair colour variation

In Akool’s system, the customization function for hair color is set up so that users can adjust their hair colour to match their skin tone and clothing. Users can experience different feeling images through hair colors, enhancing the flexibility of face effects while meeting the diverse needs of different users.

5.Changes in body shape

Akool has introduced a special body effects function, which allows users to design their body as a whole according to the image they choose. In our algorithm, there is not only a setting for the overall figure, but also a function for adjusting individual parts of the figure. It allows the user to set up the effects as he or she wishes, meet their needs for the body as a whole thus improve the user experience all round.

(ii) Virtual human

1.Image generation

The virtual human is presented in the image of a human being.So image generation is the first step in the use of it. Akool has applied a customised approach to image generation and this has become a core feature of our image generation. Our solution supports custom design of facial parts, including all parts of the face including eyes, nose, mouth, eyebrows and nose can be adjusted to fully meet the user’s face pinching needs. For a realistic face painting experience, we have created a design with multiple dimensions that can be adjusted to ensure a detailed and nuanced image generation. In addition, the virtual images are stylistically diverse and artistically expressive, capturing every detail from facial features to skin tone. 

For image generation, users can also enter a portrait photo and the platform will generate a personalized virtual image based on the detection and extraction of facial features and on-the-fly.

We also offer a full body image product, including clothing and accessories. We also provide a full set of clothing for your custom image, including clothes, trousers, shoes and accessories, which users can customize to further suit their image needs.

2.Image driven

In terms of driving, our Avatar supports face driving, tracking facial movements in real time through face keypoint detection capability to achieve an expression-on-the-fly effect, enabling instant expression display.

3.Communication dialogue

Akool virtual human has a communication and dialogue function. The dialogue logic algorithm is fed into the virtual human system so that we could have the logic of a “human” mind and can engage in dialogue with a “human” to meet the needs of a “human”. Also, in order to enhance the user experience, our virtual human has incorporated an image and tone synchronization system, i.e. when the user enters a relevant question, the virtual human can generate its own answers to the conversation according to the system’s internal algorithm and work with the system’s algorithm. The virtual human can answer the question with a vivid tone of voice and expressions, forming an interactive dialogue with the interlocutor. Aiming to make the conversation effective and the user experience deeper, Akool has also made it possible to enhance the user experience by adding the ability to have continuous conversations, depending on the actual needs of the conversation.

An AI character generation function has also been added, which is a new breakthrough in AI technology. Firstly, with the help of the face pinching function, we design the brain, which has the function of communication and dialogue. At the same time, we have given the AI memory and learning functions, making it possible to learn and remember normal environments through logical algorithms based on the brain, and to set the AI’s personality, preferences, etc., giving it more emotion. This is a further development in anthropomorphising AI. Creating an AI brain is a new breakthrough for Akool. The AI brain exists in the form of a search engine that can interact more with people through the input of emotions, words and expressions, giving digital people a breath of life and a more realistic feel.

II. Product Applications.

1. Face effects

(1) Face Beauty

It is one of the most widely available uses today and is usually used in photo shoots to retouch faces with the face effects function, including the whitening, lifting, slimming and wide-eyed areas, as well as custom attributes. Akool’s face effects function can enhance photos and improve image quality.

(2) Beauty special effects

Akool has added a beauty special effects function, which allows users to apply facial makeup on top of their image according to their makeup needs, including light makeup, smoky makeup, faux makeup, etc. A variety of styles and experiences allow users to experience themselves under different makeup looks, which is more novel relative to users.

(3) Dynamic stickers

This is a use of face effects that distinguishes them from photographs, turning the static into the dynamic. When the user appears in the shot, Akool can automatically generate an algorithm through the facial recognition system to form a corresponding sticker on the person’s face. The stickers are more dynamic than a static photo, making them the main face special effects used by many people today.

(4) Animated animal avatar

Animal dynamic avatars are a materialization of the dynamic sticker application. In the sticker application, the stickers are materialized as small animals, making the settings more detailed, such as the animal’s ears, hair colour, whiskers, etc. The realism of the animals is accentuated by the image effects, while the dynamic and movable images are set up to make the experience more powerful and multi-dimensional in perspective.

(5) Dynamic mask

The dynamic mask is also a materialization of the dynamic sticker application, the materialized image here being the mask. When the user appears in front of the camera, Akool generates the mask by recognizing the automatic production algorithm. Moreover, the mask is set up with an auto-adjustment function, which automatically recognizes the silhouette and retouches the silhouette according to the face of the person in the shot.At the same time, the mask can be adjusted according to the shape and the size of the face, making the mask a better match for the fan user and improving the matching of the dynamic mask application.

1.Virtual human

(1) Spokesperson

Virtual men are currently used in the field of corporate spokespersons, replacing real people when promoting products and images related to companies.

(2) Cartoon image

The application of cartoon images is usually found in anime, where the cartoon image of the virtual human makes the effect more realistic and makes the user more immersive, i.e. more three-dimensional. For example, the current live streaming platform has a live avatar function, which can be designed with different actions according to different scenes and needs, increasing the user experience.

(3) User orientation

It gives the virtual human the intelligent thinking of a human being, as well as the human behaviour, so that he can provide services to consumers, thereby understanding their consumption habits, segmenting the market, providing personalized services according to customer’s needs, and improving their user satisfaction better.

This is known as the customer profiling function of the virtual human. Economic development is driving the competition in the market, and companies can provide more personalized services to consumers through AI profiling capabilities.

III. Scenarios of use

(1) Brand endorsement

Manufacturers can communicate with consumers through virtual humans to facilitate a connection with them, thereby increasing consumer awareness of the brand. Manufacturers can communicate with consumers through virtual humans to facilitate a connection with them, thereby increasing consumer awareness of the brand. For example, the current eponymous brand virtual image IP of Florasis can create emotional value for consumers and increase their perception of Florasis by using virtual human instead of real people to appear in live commerce.

(2) Product display

The virtual human is not only a “human” concept, but can also appear in other forms as a virtual image, presenting a full range of products. For example, car shows that are currently online and in use, some car companies will showcase the company’s new cars through virtual human at their launch events. Compared to traditional forms of car show, virtual  images of cars are more vivid and can be displayed in multiple contexts at the same time, making the consumer experience more powerful.

(3) Provision of services in virtual space for users

In contrast to the previous two forms, this function, which offers consumers a virtual space, is more dynamic and also reflects the service function of the virtual human. In this case, the virtual human can be set up as a virtual employee of the enterprise, providing services to consumers by means of virtual space, for example, leading consumers to review their history and displaying new products of the company; paying bills and socializing in daily life with the help of virtual business hall. Of course, the application of virtual employees is still limited by technology, and can only temporarily stay in the virtual anchor stage. However, as the technology develops and the virtual human technology innovates, the virtual human technology will reconstruct the virtual space of “human, goods and live room” in the future, enhancing the experience for users, which is often referred to as the meta-universe era.

(4) Live commerce

Virtual human can be applied in the modern network of live commerce, and with the rise of the digital economy, virtual human can take on the role of existing live anchor through virtual image in the live room for the introduction of line products. The application of virtual anchors ensures that the live broadcast can be carried out in a way that does not require a live person to appear in the live broadcast, while Akool virtual people can personalize the live content, live image, live language and other live broadcast-related content to meet the different live broadcast needs of different companies.
