Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, are disclosed for track simplification and correction. In one aspect, a track data set having track points defining a course can be accessed and inaccurate track points and incorrect track points can be identified, wherein identifying inaccurate track points includes comparing, for one or more of the track points, a dilution of precision (DOP) value associated with the track point to a DOP threshold, and identifying incorrect track points includes performing an error correction process. Also, a corrected track can be generated by removing identified inaccurate track points and incorrect track points from the track data set. Further, identifying an inaccurate track point can include determining that the DOP value associated with the track point exceeds the DOP threshold. Additionally, the DOP threshold can be specified by user input.

Abstract: Methods and systems are presented for organizing images. In one aspect, a method can include generating a correlation value indicating a likelihood that a face included in a test image corresponds to a face associated with a base image, determining that a correlation threshold exceeds the correlation value and that the correlation value exceeds a non-correlation threshold, generating a similarity score based on one or more exposure values and one or more color distribution values corresponding to the test image and the base image, combining the similarity score with the correlation value to generate a weighted correlation value, and determining that the test image and the base image are correlated when the weighted correlation value exceeds the correlation threshold.

Abstract: Some embodiments provide an image editing application that allows users to quickly preview images and to edit images. The image-editing application provides a quick preview tool for foregoing the loading of a particular image in the display area after the particular image has been selected. Specifically, for each particular image, the image-editing application maintains or generates a preview image for the particular image. In place of a particular image, the quick preview tool when selected causes the image editing application to only load the preview image of the particular image for full or partial display in the display area. When the quick preview tool is not selected, the image editing application loads each image in its entirety for full or partial display in the display area.

Abstract: Some embodiments provide a method that from a source external to a device, imports a first image and a lower resolution second image that corresponds to the first image into the device. The method assigns the second image as a temporary preview of the first image. The method generates a preview third image for the first image. In some embodiments, the method further selects the first image for display before generating the preview third image. The selecting causes the temporary preview image to be displayed as a preview of the first image. In some embodiments, the method further selects the first image for display after generating the preview third image. The selecting causes the preview third image to be displayed as a preview of the first image.

Abstract: The invention described herein is directed to a search engine configured to locate data within a defined domain. The user may input keywords and graphically select one or more attributes for conducting a search. The system then utilizes the keywords and other attributes and classification terms to define one or more search domains (e.g., dimensions). The keywords are tightly associated with an index that represents data within the search domain. For instance, one embodiment of the invention utilizes metadata to build an index that associates a set of files (e.g., audio files) with a number of distinct classifications expressed in the form of the exposed set of keywords. To this end, the method involves a mechanism for defining and collecting metadata.

Abstract: A method for indexing audio files to provide a small number of good matches from a search engine is presented. An indexer parses the audio files and generates search keywords which are presented to a user via a graphical user interface. The keywords presented to the user are only those keywords that matched tags obtained from the audio files that were indexed. Thus, the user is never presented information that will not provide a valid search. The user's search query is simply a selection of one of the keywords presented by the indexer. The user can further narrow the search results to audio files that are within a predetermined number of semitones of the project tone. Thus, users need not waste time listening to audio files that are completely out of tone with their projects when search for a particular audio file.

Abstract: A data transfer technique in which lossy connections or temporarily interrupted network links neither prevent data transfer nor substantially impair the ease with which a user can transfer data. A sender is advised of receivers on a network that are available to receive data over the network. Also, while data transfer from a sender to a receiver is being performed, the availability of the receiver is monitored. If, during the data transfer, the receiver becomes unavailable to receive the data, then the data transmission stops and the sender is informed that the receiver has become unavailable. The sender continues to monitor the network to determine if the receiver has regained its availability. If the receiver regains availability, the sender is able to automatically resume the data transmission, provided the availability is regained before the network connection is completely lost. The invention is useful for wireless networks as well as wired networks.
