摘要： An embodiment generally relates to systems and methods for determining cell phone usage automatically by individuals operating vehicles. A processing module can process multi-spectral images or videos of individuals and detect different regions in the image such as face regions, hand regions, and cell phone regions. Further, the processing module can analyze the regions based on locations and numbers of skin pixels and cell phone pixels to determine if the individual is holding his or her cell phone near his or her face. Based on the analysis, it can be determined whether the individual is operating the cell phone. Further, the analysis can yield a confidence level associated with the cell phone usage.

摘要： Compensation for rendering device non-uniformities is provided for halftoned images. A spatially dependent tone reproduction curve (TRC) provides compensation values. Pixel location information is used to access TRC values. For example, the values are modification values. The modification values are added to the pixel values to generate combined values. Quantization is applied to the combined values to prepare compensated image data for rendering. For example, Rank Ordered Error Diffusion is applied to the combined values. The combined values may include diffused error from previously processed pixels. Gray values may be estimated for the respective pixels. The estimated gray values may be used to access compensation information from a TRC that is both spatially and gray value dependent. Mathematical basis decomposition is used to reduce TRC memory requirements. For example, Discrete Cosine Transformation, Singular Value Decomposition or Principal Component Analysis is used to determine a compact form for the TRC.
摘要翻译： 为半色调图像提供渲染设备不均匀性的补偿。 空间依赖色调再现曲线（TRC）提供补偿值。 像素位置信息用于访问TRC值。 例如，值是修改值。 将修改值添加到像素值以生成组合值。 将量化应用于组合值以准备用于渲染的补偿图像数据。 例如，将秩排序误差扩散应用于组合值。 组合的值可以包括来自先前处理的像素的扩散误差。 可以针对各个像素估计灰度值。 估计的灰度值可用于从空间和灰度依赖的TRC访问补偿信息。 数学基础分解用于减少TRC记忆体要求。 例如，使用离散余弦变换，奇异值分解或主成分分析来确定TRC的紧凑形式。

摘要： Image data is scaled, rotated and/or otherwise manipulated. Diffusive effects of associated interpolation and/or re-sampling are compensated for, or corrected, by applying an adaptive packing form of error diffusion to output data of one or more manipulating transforms. For example, rank order error diffusion is applied to output data of a manipulating transform, thereby restoring compaction to otherwise diffuse halftone structures (e.g., halftone dots, lines, etc), saturated text and/or other small, high contrast image elements.

摘要： Images that include halftone structures are sharpened. A copy of received halftone image data is blurred, thereby reducing a detectability of edges of the halftone structures. Edges remaining in the blurred image data are detected. An edge enhancement image is generated based on the detected edges. The original received halftone image data is combined with the edge enhancement image, thereby generating sharpness enhanced image data having halftone structures. The sharpness enhanced image data having halftone structures can be rendered through a halftone screen that is compatible with a halftone screen that was used to generate the originally received image data. Alternatively, the sharpness enhanced image data having halftone structures is rendered according to error diffusion techniques, such as, rank order error diffusion in order to achieve or maintain dot or halftone structure compaction.

摘要： This closure provides image processing methods and apparatus for corner enhancing a digital image for rendering on an image output device. According to an exemplary method, the method determines whether or not image pixels are associated with a corner as a function of the USAN values generated for the image pixels. Subsequently, one or more pixels associated with a corner are modified to render a corner enhanced image.
