摘要： As set forth herein, computer-implemented methods and systems facilitate watermarking documents and/or images using 2nd generation stochastic halftoning. The watermark is used to spatially vary the gray level at which a frequency modulation-to-amplitude modulation transition occurs. The encoding algorithm uses as inputs a contone image and a watermark. The visibility of the watermark is controlled by the magnitude of the difference between the AM-to-FM transition threshold values.

摘要： When estimating distance to an object in an image using a single camera, data acquired by an onboard accelerometer is analyzed to determine camera speed as the user takes a video of the object of interest. The compression that results during video processing is used to derive motion vectors for the object of interest in the scene. The motion vectors have an opposite direction to the camera motion and a magnitude that is a function of the unknown object distance and a known magnification level. The object distance is calculated from the estimated velocity and motion vector magnitude.

摘要： As set forth herein, computer-implemented methods and systems facilitate halftoning using a parametrically controlled spot function based on triangle tessellation, which in turn facilitates dot growth control of periodic halftone using an irregular seed structure. The spot function determines the shape of the halftone dot used to reproduce a given pixel. The spot function is well suited for growing halftone dots arrayed on a non-regular grid and can also be used for grids with regular order. The spot function includes adjustable parameters for controlling its sharpness and slope.

摘要： As set forth herein, computer-implemented methods and systems facilitate employing a single stochastic screen defined up to a specified transition level. The dots at the specified level are connected to form a triangle tessellation with an associated spot function. For up to three colorants, a vector screening technique is employed, which involves a first colorant dot being grown from the vertices, second colorant dot grown from the triangle center, and a third colorant dot grown from the side midpoints. Growth in this manner ensures separation of colorants up to a certain density level. In cases where fourth colorant is to be used at a given pixel, the fourth colorant can be added using methods typically used for clustered screens, such as stochastic screening of the lightest colorant, in order to mitigate color shift sensitivity issues.
摘要翻译：如本文所述，计算机实现的方法和系统便于采用在特定过渡级别之下定义的单个随机屏幕。指定级别的点被连接以形成具有相关联的点功能的三角形细分。对于最多三种着色剂，使用载体筛选技术，其包括从顶点生长的第一着色剂点，从三角形中心生长的第二着色剂点和从侧面中点生长的第三着色剂点。以这种方式生长确保着色剂的分离达到一定的密度水平。在给定像素处使用第四着色剂的情况下，可以使用通常用于聚类屏幕的方法（例如最轻的着色剂的随机筛选）来添加第四着色剂，以减轻色移敏感性问题。

摘要： As set forth herein, computer-implemented methods and systems facilitate halftoning by adapting 2nd generation halftone techniques to the spatial frequency content of an image utilizing a spot function introduced in conjunction with a technique for determining seed locations, which results in halftone images exhibiting improved edge and detail rendition. A dominant orientation of pixels in an input image is employed to select a pre-generated stochastic screen used to determine the seed locations.

摘要： A method of, and system for, selective video frame compression and decompression is presented. The disclosed technique is particularly suited for efficient event-driven searching in large databases. The technique involves designating certain frames in a video sequence as reference frames, to be compressed using a first compression technique, where the remaining frames are compressed using a second compression technique. The first compression technique may be implemented without requiring data from any neighboring frames.

摘要： Images are prepared for blending with a reflection. Angles of incidence and angles or reflection lead to reflections of a viewer appearing to be different than actual size. Accordingly, image preparation can include scaling images of objects to be blended with a reflection to an appropriate size. For a flat specular surface the size is one half the size the object would be if the object were sized to be associated with the feature that is reflected. A viewer will focus on the reflection of the viewer at an object plane. An image associated with the specular surface will be blurred. Accordingly, the preparation can include compensating for the blurring. Preparation can also include reducing an area coverage of the image of the object to no more than about fifty percent of the region of the refection to provide space for the reflection.
摘要翻译：图像准备与反射混合。入射角和角度或反射导致观察者的反射似乎与实际尺寸不同。因此，图像准备可以包括将要与要反射的混合的对象的图像缩放到适当的大小。对于平坦的镜面，如果对象的大小与要反映的要素相关联，则大小是对象大小的一半。观众将集中在观察者在物体平面上的反射。与镜面相关联的图像将会模糊。因此，该制剂可以包括补偿模糊。制备还可以包括将对象的图像的面积覆盖范围减小到不超过反射区域的大约百分之五十，以提供反射的空间。
