摘要： A system and method for comparing images by calculating an edit distance between the images using the results of matching portions of one image to the other. The first image is divided into blocks of pixels. For every block of pixels, a closest match is found in the second image. Substitution is equated to the sum of the errors in the closet matches. Deletion is equated to the percentage of the second image not involved in any of the matching. Insertion is equated to the percentage of the second image simultaneously involved in matching more than one block. The image edit distance may then be calculated as the weighted sum of the insertion, deletion and substitution. Recognition may be done by finding a minimum edit distance between an image of an unknown object and a set of reference images.
摘要翻译：一种用于通过使用一个图像的匹配部分到另一个图像的结果计算图像之间的编辑距离来比较图像的系统和方法。第一个图像被分成像素块。对于每个像素块，在第二个图像中找到最接近的匹配。替换等于衣柜匹配中的错误总和。删除等于任何匹配中不涉及的第二个图像的百分比。插入等于与匹配多于一个块的同时涉及的第二个图像的百分比。然后可以将图像编辑距离计算为插入，删除和替换的加权和。可以通过找到未知对象的图像与一组参考图像之间的最小编辑距离来进行识别。

摘要： The present invention relates to mitigating the effects of distortions in pulse shape and energy of spectrum from gamma ray and/or neutron detectors. In one embodiment, the present invention uses pattern recognition techniques to identify and separate various distortions in the pulse shape and energy to obtain a better estimate of the true number of pulses of specific energies which are characteristic of the radioactive materials present. Additionally, autoregressive models, pulse filtering and pattern recognition methods are used to obtain more accurate pulse characterization. In one embodiment, the present invention relates to a method of detecting a material comprising the steps of deriving an energy spectrum from nuclear radiation detected from the material, processing the energy spectrum for enhancing the energy spectrum, extracting one or more features from the enhanced energy spectrum, and classifying the material based on the one or more features.

摘要： A system and method of processing an ultrasound signal may include, in response to receiving a set of complex frequency samples of the ultrasound signal inclusive of content data and noise at a first noise level and being used to image an anatomical region of a body, resampling multiple subsets of complex frequency samples from the set of complex frequency samples. The resampled subsets of complex frequency samples may be resampled from a first domain into a second domain. The transformed resampled subsets of complex frequency samples may be combined in the second domain to produce a result signal with a second noise level reduced from the first noise level. An image derived from the result signal may be displayed.

摘要： A system and method for incorporating relevance feedback into an image search. A multimedia database is first searched using a domain specific similarity matrix (DSM), resulting in a list of image results ranked by their similarity to a query key-image. The results are then reexamined using a personalized similarity matrix (PSM). The PSM includes image that have been selected by the user, either in previous searches or from lists of candidate images. Similarity scores are calculated between the domain relevant images in the PSM and the results images. The new similarity scores are combined with the original similarity scores and the images is re-ranked into a final results list. Any images selected by the user may then be used to update and/or expand the PSM.

摘要： An encoding method for reducing motion video data sizes using a multitude of variable-sized data blocks that are derived from spatial translation vectors and the motion field of an image. Using variable-block sizes to characterize the groups of picture elements (pixels) in an image frame allows for the inter-mixing of coarse (for static areas) and fine (for areas of complex motion) resolution data descriptions in the same descriptive data block.A comparison of motion event areas is made between successive video frames, and a motion displacement vector is calculated for each pixel location in the frame. A data tree is constructed from these pixel motion vectors and is pruned to eliminate static areas. The remaining leaves of the pruned tree are encoded differentially and applied to a lossless arithmetic encoder to provide a significantly reduced data block that still retains the highest resolution of the image.
摘要翻译：一种用于使用从空间转换向量和图像的运动场导出的多个可变大小的数据块来减少运动视频数据大小的编码方法。使用可变块大小来表征图像帧中的图像元素（像素）组允许在相同的描述性数据块中的粗略（对于静态区域）和精细（对于复杂运动区域）分辨率数据描述的混合在连续的视频帧之间进行运动事件区域的比较，并且针对帧中的每个像素位置计算运动位移矢量。从这些像素运动矢量构建数据树并修剪以消除静态区域。修剪树的剩余叶子被差分地编码并应用于无损算术编码器，以提供仍然保持图像的最高分辨率的显着减小的数据块。

摘要： A system and method for searching multimedia databases using a pictorial language, input via an iconic interface and making use of trained ontologies, i.e., trained data models. An iconic graphic user interface (GUI) allows a user to specify a pictorial query that may include one or more one or more key-images and optional text input. Similarities between the query key-images and images in a multimedia database based on a pictorial edit distance are used to select the images that are the closest match to the query. The result images are returned to the user in order of their relevance to the query.
