This also includes modifications to stored content, such as video clips in a gallery that may be modified. For example, in a device with access to multiple augmented reality content generators, a user can use a single video clip with multiple augmented reality content generators to see how the different augmented reality content generators will modify the stored clip. For example, multiple augmented reality content generators that apply different pseudorandom movement models can be applied to the same content by selecting different augmented reality content generators for the content.
  • real-time video capture may be used with an illustrated modification to show how video images currently being captured by sensors of a device would modify the captured data.

Transformation of frames of a video stream can be performed by different methods for different kinds of transformation. For example, for transformations of frames mostly referring to changing forms of object's elements characteristic points for each of element of an object are calculated (e.g., using an Active Shape Model (ASM) or other known methods). Then, a mesh based on the characteristic points is generated for each of the at least one element of the object.

  • the frames of the video stream can be transformed by modifying the elements of the object on the basis of the sets of first and second points and the mesh, in such method, a background of the modified object, can be changed or distorted as well by tracking and modifying the background.
  • transformations changing some areas of an object using its elements can be performed by calculating of characteristic points for each element of an object and generating a mesh based on the calculated characteristic points. Points are generated on the mesh, and then various areas based on the points are generated. The elements of the object are then tracked by aligning the area for each element with a position for each of the at least one element, and properties of the areas can be modified based on the request for modification, thus transforming the frames of the video stream. Depending on the specific request for modification properties of the mentioned areas can be transformed in different ways.
  • Such modifications may involve changing color of areas; removing at least some part of areas from the frames of the video stream, including one or more new objects into areas which are based on a request for modification; and modifying or distorting the elements of an area or object.

One shape is aligned to another with a similarity transform (allowing translation, scaling, and rotation) that minimizes the average Euclidean distance between shape points. The mean shape is the mean of the aligned training shapes.
  • a search for landmarks from the mean shape aligned to the position and size of the face determined by a global face detector is started.

  • the phrase ‘hardware component’ should be understood to encompass a tangible entity, be that an entity that is physically constructed, permanently configured (e.g., hardwired), or temporarily configured (e.g., programmed) to operate in a certain manner or to perform certain operations described herein.
  • hardware components are temporarily configured (e.g., programmed)
  • each of the hardware components need not be configured or instantiated at any one instance in time.
  • a hardware component comprises a general-purpose processor configured by software to become a special-purpose processor
  • the general-purpose processor may be configured as respectively different special-purpose processors (e.g., comprising different hardware components) at different times.
  • Hardware components can provide information to, and receive information from, other hardware components. Accordingly, the described hardware components may be regarded as being communicatively coupled. Where multiple hardware components exist contemporaneously, communications may be achieved through signal transmission (e.g., over appropriate circuits and buses) between or among two or more of the hardware components. In embodiments in wdiich multiple hardware components are configured or instantiated at different times, communications between such hardware components may be achieved, for example, through the storage and retrieval of information in memory structures to which the multiple hardware components have access.
  • one hardware component may perform an operation and store the output of that, operation in a memory device to which it is communicatively coupled. A further hardware component may then, at a later time, access the memory device to retrieve and process the stored output. Hardware components may also initiate communications with input or output devices, and can operate on a resource (e.g., a collection of information).
  • a resource e.g., a collection of information.
  • the various operations of example methods described herein may be performed, at least partially, by one or more processors that are temporarily configured (e.g., by software) or permanently configured to perform the relevant operations. Whether temporarily or permanently configured, such processors may constitute processor-implemented components that operate to perform one or more operations or functions described herein.
  • processor-implemented component refers to a hardware component implemented using one or more processors.
  • the methods described herein may be at least partially processor-implemented, with a particular processor or processors being an example of hardware. For example, at least some of the operations of a method may be performed by one or more processors or processor-implemented components.
  • the one or more processors may also operate to support performance of the relevant operations in a ‘cloud computing’ environment or as a ‘software as a service’ (SaaS).
  • SaaS software as a service
  • the operations may be performed by a group of computers (as examples of machines including processors), with these operations being accessible via a network (e.g., the Internet) and via one or more appropriate interfaces (e.g., an API).
  • the performance of certain of the operations may be distributed among the processors, not only residing within a single machine, but deployed across a number of machines.
  • the processors or processor-implemented components may be located in a single geographic location (e.g., within a home environment, an office environment, or a server farm). In other example embodiments, the processors or processor-implemented components may be distributed across a number of geographic locations.
  • Carrier Signal refers to any intangible medium that is capable of storing, encoding, or carrying instructions for execution by the machine, and includes digital or analog communications signals or other intangible media to facilitate communication of such instructions. Instructions may be transmitted or received over a network using a transmission medium via a network interface device.
  • Computer-Readable Medium refers to both machine- storage media and transmission media. Thus, the terms include both storage devices/media and carrier waves/modulated data signals.
  • machine-readable medium,’ ‘computer-readable medium’ and ‘device-readable medium’ mean the same thing and may be used interchangeably in this disclosure.
  • Client Device refers to any machine that interfaces to a communications network to obtain resources from one or more server systems or other client devices.
  • a client device may be, but is not limited to, a mobile phone, desktop computer, laptop, portable digital assistants (PDAs), smartphones, tablets, ultrabooks, netbooks, laptops, multi-processor systems, microprocessor-based or programmable consumer electronics, game consoles, set- top boxes, or any other communication device that a user may use to access a network.
