摘要： A compressed light field imaging system is described. The light field 3D data is analyzed to determine optimal subset of light field samples to be (acquired) rendered, while the remaining samples are generated using multi-reference depth-image based rendering. The light field is encoded and transmitted to the display. The 3D display directly reconstructs the light field and avoids data expansion that usually occurs in conventional imaging systems. The present invention enables the realization of full parallax 3D compressed imaging system that achieves high compression performance while minimizing memory and computational requirements.

摘要： A method for recognizing a change of a relative yaw angle at a stereo video system for a vehicle. An image pair is read in from first and second cameras at a first time, and a further image is read in from the first camera at a later time. A stationary surface is ascertained using the image pair and the stereo base to obtain an angle of inclination of the stereo video system. The stationary surface is determined using the first image of the image pair and the further image to obtain a comparison angle. A correspondence transformation between the first image and the further image is acquired if the stereo video system has moved by a distance between the first time and the further time. The angle of inclination is compared with the comparison angle to recognize the change of the relative yaw angle.

摘要： Mobile phones and other portable devices are equipped with a variety of technologies by which existing functionality can be improved, and new functionality can be provided. Some aspects relate to visual search capabilities, and determining appropriate actions responsive to different image inputs. Others relate to processing of image data. Still others concern metadata generation, processing, and representation. Yet others concern user interface improvements. Other aspects relate to imaging architectures, in which a mobile phone's image sensor is one in a chain of stages that successively act on packetized instructions/data, to capture and later process imagery. Still other aspects relate to distribution of processing tasks between the mobile device and remote resources (“the cloud”). Elemental image processing (e.g., simple filtering and edge detection) can be performed on the mobile phone, while other operations can be referred out to remote service providers. The remote service providers can be selected using techniques such as reverse auctions, through which they compete for processing tasks. A great number of other features and arrangements are also detailed.

摘要： A game apparatus includes a CPU, and in a mode of examining a flower based on an imaged image, the CPU activates two outward cameras to allow a user to image a flower. The CPU obtains color information, shape information and a size of the imaged flower from the imaged image. A shape category is obtained from the shape information, and with the shape category, data for search included in a database for search is filtered. Then, by comparing color information, shape information, and the size of the imaged flower with the data for search to be used, a score of a degree of approximation of the color information and scores of the degree of matching of the shape information and size, etc. are obtained. Then, images of flowers as candidates are presented in the descending order of the score (similarity level).
