Abstract: Each of multiple images is analyzed to determine how the colors of the pixels of the image are distributed throughout the color space of the image. Different covariance based characteristics of the image are determined that identify a direction, as well as magnitude in each direction, of the distribution of colors of the image pixels. These different covariance based characteristics that are determined for an image can be saved as associated with the image, allowing the characteristics to be accessed and used as a basis for searching the images to identify particular types of images. These different covariance based characteristics can also be used to order the images identified by a search.

Abstract: Methods and apparatus are presented for a morphing search tool that provides a single user interface through which a user may both modify a displayed image and perform an image similarity query based on the modified image. The morphing search tool may allow a user to repeat this process until a desired image is found and displayed. Further, the image repository to be searched may be specified by a user and the images to be modified and searched for may be any type of image. The morphing search tool may be integrated within a merchant website, an image management system, or as a stand alone application.

Abstract: Systems and methods are disclosed to adjust the loudness or another audio attribute for one or more audio clips. Intra-track audio levels can automatically be equalized, for example, to achieve a homogeneous audio level for all clips within an audio track. Information about such audio adjustments may be identified and stored as information without destructively altering the underlying clip content. For example, keyframes may define changes to a fader that will be applied at different points along a track's timeline to achieve the audio adjustments when the track is played. An audio editing application can provide a feature for automatically determining appropriate keyframes, allow manual editing of keyframes, and use keyframes to display control curves that represent graphically the time-based adjustments made to track-specific faders, play test audio output, and output combined audio, among other things.

Abstract: A method, apparatus and computer program product for mixing audio is presented.

The background clips are analyzed and a distance value between the loudness corrected foreground clips and the background clips is defined. Keyframes are added to some of the audio clips, the keyframes providing a fade between levels of the background clips to take into account the loudness corrected foreground clips and a sequenced audio file is produced from the corrected foreground clips, the background clips and the keyframes.

Abstract: An audio storage architecture allows an audio management application to manipulate and recombine segments of a musical piece such that the resulting finished composition includes parts (segments) from the decomposed piece, typically a song, adjustable for length by selectively replicating particular parts and combining with other parts such that the finished composition provides a similar audio experience in the predetermined duration. The architecture defines the parts with part variations of independent length, identified as performing a function of starting, middle, (looping) or ending parts. Each of the parts provides a musical segment that is integratable with other parts in a seamless manner that avoids audible artifacts (e.g. “pops” and “crackles”) common with conventional mechanical switching and mixing.
