摘要： A similarity of a first video to a second video may be identified automatically. Images are received from the videos, and divided into sub-images. The sub-images are evaluated based on a feature common to each of the sub-images. Binary representations of the images may be created based on the evaluation of the sub-images. A similarity of the first video to the second video may be determined based on a number of occurrences of a binary representation in the first video and the second video.

摘要： Techniques describe submitting a video clip as a query by a user. A process retrieves images and information associated with the images in response to the query. The process decomposes the video clip into a sequence of frames to extract the features in a frame and to quantize the extracted features into descriptive words. The process further tracks the extracted features as points in the frame, a first set of points to correspond to a second set of points in consecutive frames to construct a sequence of points. Then the process identifies the points that satisfy criteria of being stable points and being centrally located in the frame to represent the video clip as a bag of descriptive words for searching for images and information related to the video clip.

摘要： Technologies for recommending relevant tags for the tagging of media based on one or more initial tags provided for the media and based on a large quantity of other tagged media. Sample media as candidates for recommendation are provided by a set of weak rankers based on corresponding relevance measures in semantic and visual domains. The various samples provided by the weak rankers are then ranked based on relative order to provide a list of recommended tags for the media. The weak rankers provide sample tags based on relevance measures including tag co-occurrence, tag content correlation, and image-conditioned tag correlation.

摘要： Techniques for construction of a visual codebook are described herein. Feature points may be extracted from large numbers of images. In one example, images providing N feature points may be used to construct a codebook of K words. The centers of each of K clusters of feature points may be initialized. In a looping or iterative manner, an assignment step assigns each feature point to a cluster and an update step locates a center of each cluster. The feature points may be assigned to a cluster based on a lesser of a distance to a center of a previously assigned cluster and a distance to a center derived by operation of an approximate nearest neighbor algorithm having aspects of randomization. The loop terminates when the feature points have sufficiently converged to their respective clusters. Centers of the clusters represent visual words, which may be used to construct the visual codebook.
摘要翻译：本文描述了构建视觉码本的技术。特征点可以从大量图像中提取出来。在一个示例中，提供N个特征点的图像可以用于构造K个字的码本。可以初始化K个特征点中的每一个的中心。以循环或迭代的方式，分配步骤将每个特征点分配给集群，并且更新步骤定位每个集群的中心。可以基于距先前分配的簇的中心的距离中较小的一个特征点来分配特征点，以及通过具有随机化方面的近似最近邻算法的操作导出的到中心的距离。当特征点已经充分收敛到它们各自的簇时，环路终止。集群的中心表示视觉词，可用于构建视觉码本。

摘要： Colorblind accessible image search technique embodiments are presented that re-rank the results of a relevance-ranked image search to account for the accessibility of the images to a colorblind person. This is accomplished by first computing a colorblind accessibility quantity for each image of interest in the search results. A colorblind accessibility quantity quantizes the degree to which color information is preserved when an image is perceived by a colorblind person viewing the image. It is computed by generating a colorblind version of an image that simulates how the image would appear to the colorblind person. An amount quantifying the loss of color information between the image and the colorblind version of the image is then estimated. This estimate is used to compute the colorblind accessibility quantity for the image. Once the colorblind accessibility quantities have been computed, the image search results are re-ranked based on these quantities.
摘要翻译：呈现了彩色盲可访问图像搜索技术实施例，其对排序相关的图像搜索的结果进行重新排序，以便将图像的可访问性应用于彩色盲人。这是通过首先计算搜索结果中感兴趣的每个图像的色盲辅助数量来实现的。彩色可见量可以量化当查看图像的彩色盲人感知到图像时保留颜色信息的程度。它通过生成图像的彩色版本来计算，该图像模拟图像将如何显示给彩色盲人。然后估计量化图像和图像的彩色版本之间的颜色信息的损失的量。该估计用于计算图像的色盲辅助数量。一旦计算了色盲辅助数量，就会根据这些数量重新排列图像搜索结果。
