摘要： In an embodiment of the invention, an electronic document (e-document) can be searched and found by capturing an image of the printed document. Instead of typing in a file name or searching through multiple directories, the user simply takes a picture of the document with a camera and the system uses the document image to locate the e-document. In an alternative embodiment of the invention, an image of a printed document can be useful for remote document sharing. In various embodiments of the invention, sharing an image of a printed document can be used to email a high quality paper document, send a high quality fax, or open a document to a page containing an annotation. Through co-design of the feature extraction and search algorithm in the system, the image feature detection robustness and search speed are improved at the same time.

摘要： Described is a technique for viewing a document page on a small display such as a mobile phone or PDA. The page can come from a scanned document (bitmap image) or an electronic document (text and graphics data plus metadata). The page with text and graphics is segmented into regions. For each region, a scale-distortion function is constructed based on image analysis. During interactive viewing of the document, as the user navigates by moving the viewport around the page, the zoom factor will be automatically adjusted by optimizing the scale-distortion functions of the regions in the viewport.

摘要： An automated system and method for producing videos using expert video production rules. The automated video production system and method of the present invention is particularly well-suited for the online publishing of lectures. The system of the present invention includes a camera system for capturing the lecture, such as an audience-tracking camera and a non-intrusive lecturer-tracking camera. Moreover, each camera may be controlled by a cinematographer. Tracking of a subject is performed using a history-based, reduced-motion tracker that sets up a camera shot based on the subject's movement history and leaves the shot fixed until the camera is switched. The system also includes a virtual director module having a probabilistic finite state machine (FSM) module that uses probabilistic rules and the expert video production rules to determine a current camera view.

摘要： An algorithm for finding regions of interest (ROI) in synthetic images based on an information driven approach in which sub-blocks of a set of synthetic image are analyzed for information content or compressibility based on textural and color features. A DCT may be used to analyze the textural features of a set of images and a color histogram may be used to analyze the color features of the set of images. Sub-blocks of low compressibility are grouped into ROIs using a type of morphological technique. Unlike other algorithms that are geared for highly specific types of ROI (e.g. OCR text detection), the method of the present invention is generally applicable to arbitrary synthetic images. The present invention can be used with several other image applications, including Stained-Glass collages presentations.

摘要： System and method of generating feature descriptors for image identification. Input image is Gaussian-blurred at different scales. A difference of Gaussian space is obtained from differences of adjacent Gaussian-blurred images. Key points are identified in the difference-of-Gaussian space. For each key point, primary sampling points are defined with three dimensional relative positions from key point and reaching into planes of different scales. Secondary sampling points are identified for each primary sampling point. Secondary image gradients are obtained between an image at a primary sampling point and images at secondary sampling points corresponding to this primary sampling point. Secondary image gradients form components of primary image gradients at primary sampling points. Primary image gradients are concatenated to obtain a descriptor vector for input image. Descriptor vector thus obtained is scale invariant and requires a number of additions equal to number of primary sampling points multiplied by a number of secondary sampling points.
摘要翻译：生成图像识别特征描述符的系统和方法。输入图像是不同尺度的高斯模糊。从相邻高斯模糊图像的差异获得高斯空间的差异。关键点在高斯差异空间中被识别。对于每个关键点，主要采样点被定义为从关键点到达不同尺度平面的三维相对位置。为每个主要采样点识别二次采样点。在主要采样点的图像与对应于该主要采样点的二次采样点的图像之间获得二次图像梯度。次要图像梯度在主要采样点形成原始图像梯度的分量。连接主图像梯度以获得输入图像的描述符向量。如此获得的描述符向量是不变尺度，并且需要等于一次采样点的数量乘以二次采样点数的多个加法。

摘要： The present invention relates to a method to make effective use of non rectangular display space for displaying a collage. In an embodiment of the invention, a heterogeneous set of images can be arranged to display the region of interest of the images to avoid overlapping regions of interest. The background gaps between the regions of interest can be filled by extending the regions of interest using a Voronoi technique. This produces a stained glass effect for the collage. In an embodiment of the present invention, the technique can be applied to irregular shapes including circular shapes with a hole in the middle. In an embodiment of the present invention, the technique can be used to print labels for disks.
