Researchers Submit Patent Application, "3d-Animation Effect Generation Method and System", for Approval

August 6, 2014



By a News Reporter-Staff News Editor at Electronics Newsweekly -- From Washington, D.C., VerticalNews journalists report that a patent application by the inventors VILKIN, Aleksey (Moscow, RU); SAFONOV, Ilya (Moscow, RU); KRYZHANOVSKIY, Konstantin (Moscow, RU), filed on January 9, 2014, was made available online on July 24, 2014.

The patent's assignee is Samsung Electronics Co., Ltd.

News editors obtained the following quote from the background information supplied by the inventors: "Methods and apparatuses consistent with exemplary embodiments relate to generating a three-dimensional (3D) animation effect that is implemented on a 3D display in real time.

"Various approaches to adding dynamic two-dimensional (2D) art effects to still images are known from prior-art. In particular, such solutions were widely known in many special editing tools, such as Adobe After Effects and Ulead Video Studio.

"A 2D image received by using a digital camera can be converted to an art image by performing a conversion executable on a computer so that a natural image is formed as drawn by human's hand, such as an oil-painted picture, an illustration drawn by a brush, an animation image or a mosaic.

"Recently, three-dimensional (3D) displays and 3D televisions (TVs) became very popular. However, the main volume of visual resources are still 2D. Therefore, many technical solutions are directed to conversion of 2D images and video into 3D. However, solutions known from prior-art are only to dispose a stereoscopic or moving camera, move a set of one or more animation objects, and determine a distance between a camera and objects according to a non-linear ratio, in order to visualize an image.

"3D displays are widespread now, in particular, 3D TVs with passive or active glasses. A consumer stores a considerable amount of 2D photos and video. However, 3D photos and video are spread in a much smaller degree, although there is a tendency of increase in amount of 3D content. Solutions known from prior-art do not allow real-time generation of real 3D animation effects 'on-the-fly'."

As a supplement to the background information on this patent application, VerticalNews correspondents also obtained the inventors' summary information for this patent application: "One or more exemplary embodiments provide a method and apparatus for generating a realistic 3D animation effect in real time, for multimedia objects such as a 2D image, a 3D image, or video.

"Various aspects will be set forth in part in the description which follows and, in part, will be apparent from the description, or may be learned by practice of the presented embodiments.

"According to an aspect of an exemplary embodiment, there is provided a method of generating a 3D animation effect, the method including: detecting at least one area of interest on a visual multimedia object and determining at least one feature of the detected area of interest; building a 3D scene that comprises the visual multimedia object; generating at least one 3D visual object of an animation effect in the 3D scene, according to the area of interest and the feature of the area of interest; and performing at least one of conversion of the 3D visual object in a space of the 3D scene and conversion of the 3D scene, so that the 3D animation effect is generated as a result of visualizing the 3D scene.

"The visual multimedia object may include at least one of a 2D image, a 3D image, and a video sequence.

"While the area of interest on the visual multimedia object is detected, the visual multimedia object may be pre-processed by at least one of brightness adjustment, staining, gamma correction, white color balance adjustment, and color system conversion.

"The detecting at least one area of interest may be detecting a plurality of areas of interest, and the generating the 3D visual object may be performed by randomly selecting a selected number of areas of interest from among the detected plurality of areas of interest.

"The detecting at least one area of interest may be detecting a plurality of areas of interest, and the generating the 3D visual object may be performed by selecting a selected number of areas of interest from among the detected plurality of areas of interest based on features of the selected number of areas of interest.

"The building the 3D scene may be performed by using the visual multimedia object as a texture which is superimposed on a background of the 3D scene.

"The building the 3D scene may be performed by detecting information about a scene depth regarding the visual multimedia object, and the detected information is used for building the background of the 3D scene.

"The conversion of the 3D visual object may include at least one of moving, rotation, distortion, resizing, and merging of at least two 3D objects, or dividing of a 3D object into at least two new 3D visual objects.

"The visualizing the 3D scene may be performed by using the visual multimedia object as a background of the 3D scene, and generating a 3D animation effect for the visual multimedia object.

"According to an aspect of another exemplary embodiment, there is provided an apparatus for generating a 3D animation effect on a display, the apparatus including: an interest area detection module configured to detect at least one area of interest on a visual multimedia object; a feature determining module configured to determine at least one feature of the detected area of interest on the visual multimedia object; a 3D visual object generation module configured to generate at least one 3D visual object based on the feature of the area of interest; a 3D-scene generation module configured to generate a 3D scene based on the visual multimedia object and the generated 3D visual object; a 3D conversion module configured to convert the 3D visual object in a space of the 3D scene; and a frame generation module configured to generate 3D frames by using the 3D scene that comprises the converted 3D visual object.
