Abstract: Embodiments feature families of rate allocation and rate control methods that utilize advanced processing of past and future frame/field picture statistics and are designed to operate with one or more coding passes. At least two method families include: a family of methods for a rate allocation with picture look-ahead; and a family of methods for average bit rate (ABR) control methods. At least two other methods for each method family are described. For the first family of methods, some methods may involve intra rate control. For the second family of methods, some methods may involve high complexity ABR control and/or low complexity ABR control. These and other embodiments can involve any of the following: spatial coding parameter adaptation, coding prediction, complexity processing, complexity estimation, complexity filtering, bit rate considerations, quality considerations, coding parameter allocation, and/or hierarchical prediction structures, among others.

Abstract: A wavelet transform (WT) is applied to a data stream of high definition video frames, each comprising one or more data channels digitally representing the same image. A WT is applied to each channel. Visual-quality preserving data filters and data substitution techniques are selectively applied that typically lead to at least 90-to-1 compression of the final encoded video frame. Image edge data is extracted and preserved and image noise is reduced to enhance compressibility. After the first WT, primarily low frequency (LL) image data is retained. With each later WT, more non-LL data is retained. Temporal sequences of LL images that result from the final iteration of the wavelet transform are compressed by means of a chain of invertible differenced images. Any color space can be used. Cross-channel conditional substitution is applicable. Complete multi-resolution scalability is incorporated into the encoded product. Extra-high definition video encoding is also achievable.

Abstract: In a method of encoding video content, bits of a first view and a second view of a three-dimensional (3D) video content are manipulated to occupy a first slice of video and a second slice of video, wherein a boundary is configured to be formed between the first and second slices. In addition, the bits of each of the first slice and the second slice are encoded separately from each other to form a first independently compressed video slice and a second independently compressed video slice. The first and second independently compressed video slices are then multiplexed to form at least one transport stream operable to be processed to render at least one of two-dimensional (2D) and 3D video.

Abstract: Mobile platforms are used to capture an area using a variety of sensors (e.g., cameras and laser scanners) while traveling through the area, in order to create a representation (e.g., a navigable set of panoramic images, or a three-dimensional reconstruction). However, such sensors are often precisely calibrated in a controlled setting, and miscalibration during travel (e.g., due to a physical jolt) may result in a corruption of data and/or a recalibration that leaves the platform out of service for an extended duration. Presented herein are techniques for verifying sensor calibration during travel. Such techniques involve the identification of a sensor path for each sensor over time (e.g., a laser scanner path, a camera path, and a location sensor path) and a comparison of the paths, optionally after registration with a static coordinate system, to verify that the continued calibration of the sensors during the mobile operation of the platform.

Abstract: In general, techniques are described for determining a vision-based quality metric for three-dimensional (3D) video. A device (12, 14) comprising a 3D analysis unit (24, 48) may implement these techniques to compute a 3D objective metric (36, 60). The 3D analysis unit (24, 48) estimates an ideal depth map (62, 70) that would generate a distortion limited image view using DIBR-based 3D video data (34) and then derives one or more distortion metrics (64, 72) based on quantitative comparison of the ideal depth map (62, 70) and a depth map (28, 58) used in the generation of the DIBR-based 3D video data (34). Based on the derived one or more distortion metrics (64, 72), the 3D analysis unit (24, 48) computes the objective metric (36, 60) to quantify visual quality of DIBR-based video data (34). The 3D objective metric (36, 60) may be used to alter or otherwise adjust depth estimation and encoding/decoding parameters to correct for expected visual discomfort.

Abstract: A multi-image capture device capturing images by means of circular motion controls the shift movement, along a semi-circular measuring rod, of a moving mechanism by a location control device. Furthermore, a rotary control device is used to control the positioning and image-capturing angle of a second image capture device fixed on the rotary mechanism. Thereby, a first image capture device and the second image capture device are of a co-circle configuration where the optical axis of the first image capture device and the second image capture device overlap to form a center of the co-circle. Such a configuration can broaden the visual range of the image capture device, and allows quick calibration of the image capture device according to positioning of shift movement and image-capturing angles.

Abstract: An implementation exits a power saving mode for fixed and periodic active periods of time to receive a separate burst transmission from a first stream during each of the corresponding active periods of time. The first stream is received at a first-stream burst data rate. The first stream includes data configured to be displayed at a first playback rate that is substantially less than the first-stream burst data rate. During the active periods of time, data is received from a second stream at a second-stream rate. The second stream includes data configured to be displayed at a second playback rate that is substantially the same as the second-stream rate. After receiving each of the burst transmissions from the first stream during the active periods of time, the power saving mode is entered for corresponding fixed and periodic power-saving periods of time while waiting for another burst from the first stream.
