摘要： Iris recognition is achieved by (1) iris acquisition that permits a user to self-position his or her eye into an imager's field of view without the need for any physical contact, (2) spatially locating the data defining that portion of a digitized video image of the user's eye that defines solely the iris thereof without any initial spatial condition of the iris being provided, and (3) pattern matching the spatially located data defining the iris of the user's eye with stored data defining a model iris by employing normalized spatial correlation for first comparing, at each of a plurality of spatial scales, each of distinctive spatial characteristics of the respective irises that are spatially registered with one another to quantitatively determine, at each of the plurality of spatial scales, a goodness value of match at that spatial scale, and then judging whether or not the pattern which manifests solely the iris of the user's eye matches the digital data which manifests solely the model iris in accordance with a certain combination of the quantitatively-determined goodness values of match at each of said plurality of spatial scales.

摘要： A method for fusing two or more source images to form a composite image with extended information content and apparatus for forming the composite image from the source images is disclosed. Each source image is decomposed into a number of source images of varying resolution. The decomposed source images are analyzed using directionally sensitive operators to generate a set of oriented basis functions characteristic of the information content of the original images. The oriented basis functions for the composite image are then selected from those of the different source images and the inverse of the decomposition performed to construct the composite image. Apparatus for fusing two or more source images to form a composite image is also disclosed.
摘要翻译：公开了一种用于将两个或更多个源图像融合以形成具有扩展信息内容的合成图像和用于从源图像形成合成图像的装置的方法。每个源图像被分解成多个不同分辨率的源图像。使用定向敏感算子对分解的源图像进行分析，以生成原始图像的信息内容特征的一组定向基函数。然后从不同的源图像中选择合成图像的定向基函数，并对所进行的分解的逆进行选择以构建合成图像。还公开了用于融合两个或更多个源图像以形成合成图像的装置。

摘要： A method for fusing two or more source images to form a composite image with extended information content which may be color augmented and apparatus for forming the composite image from the source images is disclosed. Each source image is decomposed into a number of source images of varying resolution. The decomposed source images are analyzed using directionally sensitive operators to generate a set of oriented basis functions characteristic of the information content of the original images. The oriented basis functions for the composite image are then selected from those of the different source images and the inverse of the decomposition performed to construct the composite image. Color augmentation provides information as to the relative weighting of the contribution of each source to the composite image.
