摘要： A first derived matrix of transport coefficients and a second derived matrix of transport coefficients are derived from a primary matrix of transport coefficients. Each of the transport coefficients describes transport of a respective image forming element from a first position onto one or more image forming elements at a second position. An approximate inverse of the first derived matrix is ascertained. A modified version of a projection image is determined from the projection image, the approximated inverse of the first derived matrix, and the second derived matrix. The modified version of the projection image is rendered from the first position onto a physical medium at the second position.

摘要： Video conferencing methods and systems that enable shared content to be displayed in a separate window within a screen or in a separate display are described. In one aspect, a method for establishing a video conference with shared content using a computing device includes capturing images of a first participant through a screen using a camera. The screen is located between the first participant and the camera. The method also includes projecting images of a second participant on the screen to be viewed by the first participant using a projector, and displaying shared content separate from the images of the second participant. The shared content is to be presented in different format than the images of the second participant presented on the screen.

A visible light camera is positioned a first spaced distance from the back side such that a field of view of the camera encompasses all or a fraction of an area of the liquid crystal panel. A visible light source is positioned a second spaced distance from the back side and outside of the field of view of the camera. A diffuser is positioned between the visible light source and the back side.

摘要： Embodiments of the present invention enable fault detection in a printed dot-pattern image. Certain applications of the present invention are its use in various embodiments of a system for inspection of a printed circuit board (“PCB”) substrate. In embodiments, a generated distortion map is based on a comparison of a reconstructed dot-pattern image, a simulated reference bitmap, and an error map representing differences between the reconstructed dot-pattern image and the reference bitmap. In embodiments, the pixels of the distortion map are color coded to identify the locations and types of aberrations that were discovered as a result of the comparison.

摘要： A projection system uses a transformation matrix to transform a projection image p in such a manner so as to compensate for surface irregularities on a projection surface. The transformation matrix makes use of properties of light transport relating a projector to a camera. If the resolution a camera is lower than that of a projector within said projection system, then the transformation matrix will have holes where image data corresponding to a projector pixel will have been lost. In this, case, new image are generated to fill-in the holes.

摘要： For each of multiple image pixels, input color component values of the pixel in an input device-dependent color space are transformed to output color component values in an output device-dependent color space characterized by an output color gamut defined by a respective gamut range for each of the output color components. In this process, the input color component values of the pixel are multiplied with corresponding elements of a device-dependent characterization matrix to produce a set of product values. The output color component values are derived from the product values. The values of a particular one of the output color components are ascertained based on a continuous nonlinear companding function that maps a function input value derived from one or more of the product values to a function output value that increases monotonically with increasing function input values over the respective gamut range of the particular output color component.
摘要翻译：对于多个图像像素中的每一个，输入设备相关颜色空间中的像素的输入颜色分量值被变换为输出设备相关颜色空间中的输出颜色分量值，其特征在于由相应色域范围定义的输出色域，每个输出颜色分量。在该过程中，像素的输入颜色分量值与设备相关特征矩阵的相应元素相乘以产生一组乘积值。输出颜色分量值是从产品值导出的。输出颜色分量中的特定值的值基于连续非线性压扩功能来确定，所述连续非线性压扩功能将从一个或多个乘积值导出的函数输入值映射到功能输出值，该函数输出值随着函数输入值的增加而逐渐增加特定输出颜色分量的各自的色域范围。
