    • Methods and arrangements involving portable devices, such as smartphones and tablet computers, are disclosed. Exemplary arrangements utilize the camera portions of such devices to identify nearby subjects, and take actions based thereon. Others rely on near field chip (RFID) identification of objects, or on identification of audio streams (e.g., music, voice). Some of the detailed technologies concern improvements to the user interfaces associated with such devices. Others involve use of these devices in connection with shopping, text entry, sign language interpretation, and vision-based discovery. Still other improvements are architectural in nature, e.g., relating to evidence-based state machines, and blackboard systems. Yet other technologies concern use of linked data in portable devices—some of which exploit GPU capabilities. Still other technologies concern computational photography. A great variety of other features and arrangements are also detailed.

    • The present invention relates generally to color image processing. One claim recites a method of color masking an image or video including: reading color values of an image sample of the image or video and a corresponding change of an attribute of the image sample; and based on the color values of the image sample, and using a programmed electronic processor, mapping the change in the image sample attribute to a change in color components of the image sample that is equivalent to the change in the image sample attribute, yet reduces visibility of the change in the image sample attribute for the specific color values of the image sample. Another claim recites a method including: obtaining data representing digital imagery or video; analyzing at least a portion of the data to determine one or more color characteristics associated with the at least a portion of the data, said act of analyzing yielding a result; based at least in part on the result, generating a key; and using a programmed electronic processor, embedding auxiliary data in the data representing digital imagery or video using the key. Of course other claims and combinations are provided as well.
    • 本发明一般涉及彩色图像处理。 一个权利要求描述了对图像或视频进行颜色掩蔽的方法,包括:读取图像或视频的图像样本的颜色值和图像样本的属性的相应变化; 并且基于图像样本的颜色值,并且使用编程的电子处理器,将图像样本属性中的变化映射到与图像样本属性的变化相当的图像样本的颜色分量的变化,但是减少 对图像样本的特定颜色值的图像样本属性的变化的可见性。 另一项声明提出了一种方法,包括:获取表示数字图像或视频的数据; 分析所述数据的至少一部分以确定与所述数据的所述至少一部分相关联的一个或多个颜色特性,所述分析动作产生结果; 至少部分地基于结果,产生密钥; 并使用编程的电子处理器,使用密钥将辅助数据嵌入到表示数字图像或视频的数据中。 当然,也提供其他权利要求和组合。
