摘要： Techniques for enhancing the reliable and efficient decoding of images of computer-readable symbols, which represent information encoded using a one- or two-dimensional visual symbology, are discussed. In accordance with one technique, prior to attempting to decode a particular image, a likelihood of successfully decoding the visual symbology from the image is determined based on a success metric. The success metric is calculated based on the blurriness of the image, or the tilt of the camera that captured the image, or both. Levels of blurriness or tilt, and the likelihood of decoding success, are ascertained with respect to predetermined reference values associated with generally decodable images. In accordance with another technique, image-sharpening algorithms are applied at select locations within the image. Such locations generally correspond to centers of modules within the visual symbology of the computer-readable symbol, which are assigned values based on grayscale values of proximate pixels in the image.

摘要： Video enhancement enable visually-apparent improvements to image frames of a video sequence. In an example implementation, stabilized or other image frames include missing image areas that are filled using a video completion technique. The missing image areas are filled in using a video completion technique that involves motion inpainting. Local motion data of a motion map from known image areas is propagated into the missing image areas to produce an extended motion map. Pixels of the missing image areas are then filled in by warping pixels from neighboring image frames into the missing image areas responsive to the extended motion map. In another example implementation, video deblurring reduces the blurriness of a current image frame. Sharper image pixels from neighboring image frames are transferred so as to replace blurry pixels of the current image frame. In yet another example implementation, video completion with motion inpainting enables amelioration of visual artifacts.

摘要： Various embodiments provide techniques for scrubbing variable paths in content. By way of example and not limitation, scrubbing can include receiving user input that defines a scrub path and navigating a data path through content based on the scrub path. According to some embodiments, a data path can include one or more predefined paths (e.g., a travel route) through the content. One or more of the techniques can account for variations in a data path and provide ways of maintaining adjacency between a scrub path and navigation along the data path. In some embodiments, a data path can be associated with one or more types of data path content that can be presented in response to a navigation of the data path.

摘要： Navigation instructions using low-bandwidth signaling are supported in an alternative user interface that may be utilized as either a full replacement or as an enhancement to conventional visual/audio navigation interfaces. In one illustrative example, the alternative interface makes use of the more constrained, but generally broadly available low-bandwidth signaling capability of mobile devices to encode navigation instructions in the form of varying patterns of tactile vibrations that may be imparted from the device to a user as haptic feedback. The user can sense the vibrations and readily translate them into the navigation instructions without needing any kind of special decoding equipment or using any special techniques. The vibrations may be encoded using easy to remember patterns so that a full and rich navigation feature set may be accessed with minimal training on the user's part.

摘要： Audio data associated with a plurality of originating sources is obtained, the audio data directed to a participant entity. An originating entity associated with one of the originating sources is determined. A listener focus indication is obtained from the participant entity indicating a listener focus on the originating entity. A spatial positional relationship is determined between the participant and originating entities. A filtering operation is initiated to enhance a portion of the audio data associated with the originating entity, the portion enhanced relative to another portion of the audio data that is associated with the originating sources other than the first one. A spatialization of a stream of the first portion that is based on a participant positional listening perspective is initiated, based on the spatial positional relationship. Transmission of a spatial stream of audio data is initiated to the participant entity, based on the filtering operation and spatialization.

摘要： Various embodiments provide techniques for calibrating and annotating video content. In one or more embodiments, an instance of video content can be calibrated with one or more geographical models and/or existing calibrated video content to correlate the instance of video content with one or more geographical locations. According to some embodiments, geographical information can be used to annotate the video content. Geographical information can include identification information for one or more structures, natural features, and/or locations included in the video content. Some embodiments enable a particular instance of video content to be correlated with other instances of video content based on common geographical information and/or common annotation information. Thus, a user can access video content from other users with similar travel experiences and/or interests. A user may also access annotations provided by other users that may be relevant to a particular instance of video content.

摘要： The present localization system determines a precise location for an address based on images. Some implementations identify the precise location using one image. Other implementations identify the precise location using multiple images. While still other implementations identify the precise location by interpolation, which uses precise locations of addresses nearby that were previously localized using one or more images. The images used in determining the precise locations have a visual feature associated with the address appearing in the image.

摘要： A video that advertises a particular web site may be a form of video spam. For example, pornographers often advertise their web sites by displaying a link to their web sites in videos, and then placing the videos on video-sharing services. This type of video spam may be detected by analyzing the video for the presence of text and then determining whether the text is a URL. If the text is a URL, the URL may be checked to determine whether it points to an objectionable web site. The determination of whether a URL points to an objectionable web site may be made by comparing the URL with a blacklist and/or whitelist, or by retrieving the URL and analyzing the retrieved content. If a video is found to be an advertisement for an objectionable web site, action may be taken, such as removing the video from a content database.
摘要翻译：广告特定网站的视频可能是视频垃圾邮件的一种形式。例如，色情作家经常通过在视频中显示他们的网站的链接来宣传他们的网站，然后将视频放在视频共享服务上。这种类型的视频垃圾邮件可以通过分析视频来检测文本的存在，然后确定文本是否是URL。如果文本是URL，则可以检查URL以确定它是否指向令人反感的网站。可以通过将URL与黑名单和/或白名单进行比较，或通过检索URL并分析检索的内容来确定URL是否指向令人反感的网站。如果发现视频是令人反感的网站的广告，则可以采取行动，例如从内容数据库中删除视频。
