[0051] In a preferred embodiment, the system 100 can also evaluate the effect of the cosmetic product before and after use of the cosmetic product for a predefined period, as shown in [Fig.2] and [Fig.3].

[0052] Fig. 2 illustrates a first example of application of system 100 in accordance with the invention.

[0053] In the first example, the dynamic wrinkles to be tested are crow's feet. System 100 is used to observe the effect of a cosmetic product on a user before and after using that cosmetic product for a predefined period. In the first example, the cosmetic product could be an anti-wrinkle cream that can be applied to any area of ​​the user's body, and the predefined period could be set at four weeks.

[0054] Before using this anti-wrinkle cream, a first set of ten continuous images is obtained by the image acquisition device 102 throughout the entire process, from the user's neutral expression to the user's maximum expression. For example, this first set of ten continuous images can be obtained by three high-speed cameras with three flashlights, respectively, from the front, left side, and right side of the user simultaneously. Only ten continuous images are shown, and any number of images can be used in the context of disclosure. Memory 103a stores this first set of ten continuous images in real time, and the crow's feet area in these images is analyzed to obtain ten clinical ratings for the crow's feet area, as based on the aging atlas, as shown in a curve with small inverted triangles in [Fig. 2].

[0055] Similarly, after applying this anti-wrinkle cream for four weeks, a second set of ten continuous images is obtained by the image acquisition device 102 throughout the entire process, from the user's neutral expression to their maximum expression. For example, this second set of ten continuous images can be obtained by three high-speed cameras with three flashlights positioned simultaneously in front of, to the left of, and to the right of the user. Memory 103a stores this second set of ten continuous images in real time and analyzes the crow's feet area in these images to obtain ten clinical scores for the crow's feet area, based on the aging of the atlas, as illustrated in a curve with small solid dots in [Fig. 2].

[0056] As shown in [Fig. 2], from a comparison between two curves for T0 and T4w, it can be seen that ten clinical notations for crow's feet wrinkles before and after using this anti-wrinkle cream, wrinkles are reduced throughout the process, from the user's neutral expression to the user's maximum expression, and therefore the anti-wrinkle effect for the crow's feet area is evident.

[0057] Fig. 3 illustrates a second example of application of system 100 according to the invention.

[0058] In the second example, the dynamic wrinkles to be tested are the nasolabial folds. System 100 is used to observe the effect of a cosmetic product on a user before and after using that cosmetic product for a predefined period. In the second example, the cosmetic product could also be an anti-wrinkle cream that can be applied to any area of ​​the user's body, and the predefined period could be set at four weeks.

[0059] Before using this anti-wrinkle cream, an initial set of ten continuous images is obtained by the image acquisition device 102 throughout the entire process, from the user's neutral expression to their maximum expression. For example, this initial set of ten continuous images can be obtained by three high-speed cameras with three flashlights, respectively, from the front, left side, and right side of the user simultaneously. Only ten continuous images are shown, and any number of images can be used in the context of disclosure. Memory 103a stores this initial set of ten continuous images in real time, and the nasolabial fold area of ​​these images is analyzed to obtain ten clinical scores for the nasolabial fold area, as illustrated in a curve with small inverted triangles in [Fig. 3].

[0060] Similarly, after four weeks of using this anti-wrinkle cream, a second set of ten continuous images is obtained by the image acquisition device 102 throughout the entire process, from the user's neutral expression to the user's maximum expression. For example, this second set of ten continuous images can be obtained by three high-speed cameras with three flashlights positioned simultaneously in front of, to the left of, and to the right of the user. Memory 103a stores this second set of ten continuous images in real time, and the nasolabial fold area in these images is analyzed to obtain ten clinical scores for the nasolabial fold area, as based on the aging atlas, as shown in a curve with small solid dots in [Fig. 3].

[0061] As shown in [Fig.2], from a comparison between two curves for T0 and T4w, it can be seen that ten clinical ratings for the nasolabial folds before and after the use of this anti-wrinkle cream are reduced throughout the process, from the user's neutral expression to the user's maximum expression, and therefore the anti-wrinkle effect for the nasolabial fold area is evident.

[0062] Figures 2 and 3 are merely examples of the disclosure and technical solutions for evaluating the effect of a cosmetic product by observing the evolution of dynamic wrinkles with facial expression. According to the disclosure, the effect of the cosmetic product can be easily observed for dynamic wrinkles on any area of ​​the user's body.

[0063] Figure 4 illustrates a functional diagram of a method 400 for evaluating dynamic wrinkles on the keratinous material of a user to be tested in accordance with a second aspect of this disclosure.

[0064] On block 401, the user to be tested is positioned by the positioning device 101. The positioning device 101 includes a head support configured to hold the user's head and ears and a height guide configured to define the user's head height. This head support and height guide can be separate components or an integrated shelf. With this arrangement, the user can be initially positioned in terms of height and left-right orientation so that the user remains stable during image capture by the image acquisition device 102. In another preferred embodiment, the user can be repositioned by components within the computing device 103 to achieve a fold-out effect in the images between different real-time shooting times.More specifically, after positioning the user for the first time, the image acquisition device 102 obtains a plurality of first images of the user at a first time point which will be viewed by an operator of the computer device 103; then the image acquisition device 102 obtains a plurality of second images of the user at a second time point which will be viewed by an operator of the computer device 103.If the operator of the computer device 103 observes that the boundaries of the plurality of the first images and the boundaries of the plurality of the second images are not aligned with each other by components within the computer device 103 to achieve the image folding effect between real-time shooting times, the user can be repositioned by adjusting the head support and the height ruler to achieve the image folding effect between the different real-time shooting times. During the repositioning process, the user to be tested is first precisely positioned by adjusting the angles and positions of their face. Then, if necessary, the height of the head, ears, etc., is adjusted. This multiple repositioning process can help the operator obtain consistent images from different time points, which is essential for the method of evaluating images of cosmetic products.

[0065] At block 402, images related to the user's facial expressions from simultaneous directions are obtained at high speed by the acquisition device of images. In a preferred embodiment, images of the user's facial expressions from at least two different sides (preferably three sides, namely front, left, and right) are obtained simultaneously by at least two (preferably three) high-speed cameras. The high-speed cameras can capture continuous images at high speed using a computing device; these images can be converted into demonstration videos for later viewing and analysis by anyone. Through the operator's voice instructions and the videos, the user being tested is guided to perform consistent facial expressions at different times. For example, during image capture, the user can relax their facial muscles, keep them relaxed, and express the following: smiling, broadly smiling, raising their eyes, becoming angry, etc.Thanks to these three high-speed cameras, a series of images ranging from neutral expressions to various expressions such as smiling, broad smiles, rolling eyes, and angry expressions can be captured at different times. In a preferred embodiment, the method also includes changing the shooting angles of each camera by adjusting a shelf configured to hold each camera. In such a preferred embodiment, each of these cameras can be located in a specially designed and adjustable shelf that can be adjusted to flexibly change the shooting angles of each camera. This shelf has an adjustable element that allows for easy adjustment of the cameras' shooting angles.

[0066] At block 403, these images are stored in real time. Later, at block 404, these images are processed to evaluate dynamic wrinkles. Dynamic image analysis is performed using an automated image analysis method, which makes it possible to measure the evolution of dynamic lines with facial expressions. In one example, a region of interest is selected from the obtained images, ranging from neutral expressions to maximized expressions; this region of interest is analyzed to obtain the evolution of dynamic wrinkles. Of course, the disclosure is not limited to such an example.

[0067] In a preferred embodiment, Method 400 also includes processing said images to obtain a clinical classification of dynamic wrinkles. In one example, the clinical classification is obtained by a dermatologist using an aging atlas or by artificial intelligence technology for the images obtained. Of course, disclosure is not limited to such an example.

[0068] In a preferred embodiment, method 400 can also evaluate the effect of the cosmetic product before and after use of the cosmetic product for a predefined period.

[0069] According to the publication, an apparatus is intended to evaluate the dynamic wrinkles on the keratin material of a user to be tested, the apparatus comprising means of executing the method according to each step of the method 500.
