Abstract: A computer implemented method and apparatus for processing images comprises obtaining two or more images acquired by ultrasound. One or more operating parameters of the ultrasound probe (transducer) are varied so that the resulting images of a material or object under investigation differ with respect to intensity. Examples of parameters which may be varied include probe angle, frequencies, and even the time and/or resolution of the respective images. The method further comprises creating a new image by selectively subtracting one or more images from one or more others. In an embodiment, there are two images and one is partially subtracted from the other. If negative values are obtained as a result of the subtraction, such values are set to zero.

Abstract: A quantum information processing system comprises a light source, a detector, at least one spatial light modulator and at least one optical lens. The light source is configured to provide a beam of entangled photons. The at least one optical lens is configured to project the resultant beam onto the spatial light modulator, either by direct imaging or by performing a full or partial optical Fourier transform. Said spatial light modulator includes a plurality of discrete pixels and is configured to select one or more of the plurality of discrete pixels to generate a resultant beam from said beam of entangled photons. The resultant beam from said spatial light modulator is projected onto the detector. For optical computation, such as search algorithms, the configuration and projections are repeated to find the optimal solution.

Abstract: A relatively high-resolution image from a conventional camera can be computationally combined with a relatively low-resolution wavefront measurement from, for example, a Shack-Hartmann sensor in order to construct a relatively high-resolution light-field image.

Abstract translation: 用于处理图像的计算机实现的方法和装置包括获得通过超声获取的两个或更多个图像。 改变超声波探头（换能器）的一个或多个操作参数，使得被研究的材料或物体的所得图像相对于强度而不同。 可以变化的参数的示例包括探针角度，频率，甚至各个图像的时间和/或分辨率。 该方法还包括通过从一个或多个其他选择性地减去一个或多个图像来创建新图像。 在一个实施例中，存在两个图像，并且一个被部分地从另一个中减去。 如果作为减法的结果获得负值，则将这些值设置为零。
