摘要： Disclosed herein are methods and systems for combining foreground video and background video using chromatic matching. In an embodiment, a system obtains foreground video data. The system obtains background video data. The system determines a color-distribution dimensionality of the background video data to be either high-dimensional chromatic or low-dimensional chromatic. The system selects a chromatic-adjustment technique from a set of chromatic-adjustment techniques based on the determined color-distribution dimensionality of the background video data. The system adjusts the foreground video data using the selected chromatic-adjustment technique. The system generates combined video data at least in part by combining the background video data with the adjusted foreground video data. The system outputs the combined video for display.

摘要： According to embodiments herein, depth key compositing is the process of detecting specific desired portionsobjects of a digital image using mathematical functions based on depth, in order to separate those specific portionsobjects for further processing. In one particular embodiment, a digital visual image is captured from a video capture device, and one or more objects are determined within the digital visual image that are within a particular depth range of the video capture device. From there, the one or more objects may be isolated from portions of the digital visual image not within the particular depth range, and the isolated objects are processed for visual display apart from the portions of the digital visual image not within the particular depth range. Also, in certain embodiments, the detected portion of the digital image (isolated objects) may be layered with another image, such as for film production, or used for holographic projection.

摘要： The present invention provides an imaging unit, a portable terminal device, and a portable terminal system capable of performing a satisfactory key synthesizing process. An imaging unit mainly includes an imaging section, a conversion section, and a key signal generating section. The conversion section converts the format of the imaged image data output from the imaging section from YUV format to RGB format. The key signal generating section generates a key signal based on each pixel data configuring the imaged image data and the reference data for the imaged image data input from the imaging section. The key signal generating section also outputs foreground image data having the generated key signal and the corresponding pixel data of RGB format as minimum configuring unit. An image synthesizing section of a main unit generates synthesized image data by overlapping the foreground image data from the imaging unit and the background image data stored in a RAM based on the key signal contained in the foreground image data.

摘要： The invention aims at separating a background area of an image using a plurality of cameras by utilizing a method of estimating a background in combination with a stereo method. Data on input images, synchronous with one another, which are obtained by photographing images of a subject from different points of sight using at least two cameras is stored in a frame memory. A background area estimation processing unit performs global image superimposition for the input images, synchronous with one another, the data on which is stored in the frame memory on the assumption that a background area is in the distance and has a flat surface. Then, the background area estimation processing unit estimates the background area based on a degree of local similarity. A distance image generation processing unit performs distance measurement with respect to points other than those in the estimated background area by utilizing a stereo method to generate distance images. A background separated image generation processing unit removes the image of an area in a predetermined distance or more from the input images by referring to resulting distance images to generate a background removed image.
摘要翻译：本发明的目的是通过利用与立体声方法组合来估计背景的方法，使用多个照相机分离图像的背景区域。通过使用至少两个照相机从不同的视点拍摄被摄体的图像获得的彼此同步的输入图像的数据被存储在帧存储器中。背景区域估计处理单元假设背景区域处于距离并且具有平坦表面的情况下，对输入图像进行全局图像叠加，彼此同步，存储在帧存储器中的数据。然后，背景区域估计处理单元基于局部相似度来估计背景区域。距离图像生成处理单元通过利用立体声方式对估计背景区域以外的点进行距离测量，以生成距离图像。背景分离图像生成处理单元通过参照所得到的距离图像从输入图像中去除预定距离以上的区域的图像，生成背景去除图像。

摘要： Foreground object matting uses flash/no-flash images pairs to obtain a flash-only image. A trimap is obtained from the flash-only image. A joint Bayesian algorithm uses the flash-only image, the trimap and one of the image of the scene taken without the flash or the image of the scene taken with the flash to generate a high quality matte that can be used to extract the foreground from the background.

摘要： An imaging device has an image compositing unit. The image compositing unit comprises: an edge extracting portion that extracts edges within an area containing a subject image in a captured image to generate edge information; an outline generating portion that generates an outline based on the edge information; an outline cutting portion that forms a partial image by cutting out an area in a captured image along the outline; and an image compositing portion that generates an image by combining a foreground image and a background image. The foreground image is a partial image formed by cutting out an area containing a subject image in a captured image either captured by an image sensor or selected from among captured images stored in memory. The background image is a captured image either captured by the image sensor or selected from among captured images stored in the memory.

摘要： A surround visual field framework or system and methods are presented. In an embodiment, a surround visual field system comprises a control signal extractor that obtains a control signal that is related to the input stream. The control signal is provided to a coupling rule that links the control signal to an effect on an element of a surround visual field. The effect is applied to the element of the surround visual field thereby creating a surround visual field that has a characteristic or characteristics which relate to an input audio/visual stream presentation. In one embodiment, the surround visual field is displayed in an area partially surrounding or surrounding the input stream being displayed. In embodiments, the surround visual field may be a rendering of a three-dimensional environment. In embodiments, one or more otherwise idle display areas may be used to display a surround visual field.
