摘要： A methodology is described to reduce the complexity of filters for face recognition by reducing the memory requirement to, for example, 2 bits/pixel in the frequency domain. Reduced-complexity correlations are achieved by having quantized MACE, UMACE, OTSDF, UOTSDF, MACH, and other filters, in conjunction with a quantized Fourier transform of the input image. This reduces complexity in comparison to the advanced correlation filters using full-phase correlation. However, the verification performance of the reduced complexity filters is comparable to that of full-complexity filters. A special case of using 4-phases to represent both the filter and training/test images in the Fourier domain leads to further reductions in the computational formulations. This also enables the storage and synthesis of filters in limited-memory and limited-computational power platforms such as PDAs, cell phones, etc. An online training algorithm implemented on a face verification system is described for synthesizing correlation filters to handle pose/scale variations. A way to perform efficient face localization is also discussed. Because of the rules governing abstracts, this abstract should not be used to construe the claims.
摘要翻译：描述了一种方法，通过将存储器需求降低到例如频域中的2位/像素来减少用于人脸识别的滤波器的复杂度。通过与量化的MACE，UMACE，OTSDF，UOTSDF，MACH和其他滤波器结合输入图像的量化傅立叶变换来实现降低复杂度的相关性。与使用全相位相关的高级相关滤波器相比，这降低了复杂度。然而，降低的复杂度滤波器的验证性能与全复杂度滤波器的验证性能相当。在傅立叶域中使用4相代表滤波器和训练/测试图像的特殊情况导致计算公式的进一步减少。这也使得能够在有限存储器和有限计算能力平台（例如PDA，蜂窝电话等）中存储和合成滤波器。描述了在面部验证系统上实现的在线训练算法，用于合成相关滤波器以处理姿态/比例变化。还讨论了执行有效面部定位的一种方法。由于管理摘要的规则，本摘要不应用于解释索赔。

摘要： Disclosed is a distortion invariant system, method and computer readable medium for detecting the presence of one or more predefined targets in an input image. The input image and a synthetic discriminant function (SDF) reference image are correlated in a shift phase-encoded fringe-adjusted joint transform correlation (SPFJTC) correlator yielding a correlation output. A peak-to-clutter ratio (PCR) is determined for the correlation output and compared to a threshold value. A predefined target is present in the input image when the PCR is greater than or equal to the threshold value.

摘要： Methods for using training images to define correlation strength surfaces about reference filters, permitting direct solution of position and orientation using images of a target object with only a few reference filters are disclosed. Correlations of selected reference filters with training images are used to develop expressions describing shapes of respective correlation surfaces at incremental changes relative to an aspect or range used for a filter. Correlations of target images with only a few reference filters may then be used to define target orientation and range in many real-world applications. A method for determining target object orientation and/or range based on interpolations, using results of correlations of a target image with composite filters having reduced sensitivities for different orientation axes, or range, is also disclosed. Techniques for using training images to create such composite filters are disclosed, as are extensions of methods to additional dimensions.
