Abstract: There is provided a method for generating a personalized Head Related Transfer Function (HRTF). The method can include capturing an image of an ear using a portable device, auto-scaling the captured image to determine physical geometries of the ear and obtaining a personalized HRTF based on the determined physical geometries of the ear.

Abstract: A method is provided for generating a personalized Head Related Transfer Function (HRTF). The method can include capturing an image of an ear using a portable device, auto-scaling the captured image to determine physical geometries of the ear and obtaining a personalized HRTF based on the determined physical geometries of the ear. In addition, a system and a method in association with the system are also provided for customizing audio experience. Customization of audio experience can be based on derivation of at least one customized audio response characteristic which can be applied to an audio device used by a person. Finally, methods and systems are provided for rendering audio over headphones with head tracking enabled by, for example, exploiting efficiencies in creating databases and filters for use in filtering 3D audio sources for more realistic audio rendering and also allowing greater head movement to enhance the spatial audio perception.

Abstract: There is provided a method for creating a stereoscopic image sequence. The method can include capturing a sequence of static images and forming a plurality of image pairs. Each image pair can include a first image and a second image selected from the sequence of static images. Selection of the first image can be done in a manner so that the image pairs are formed a spatially coherent manner. The stereoscopic image sequence can be created based on the image pairs. Creating the stereoscopic image sequence can, for example, relate to producing a stereoscopic video.
