摘要： A system and method is disclosed for determining information regarding the result of introducing a rotational force on an optical fiber during manufacturing. A rotational deformation of the molten fiber, called spin, is imparted that becomes permanent upon cooling of the fiber. The rotational force also introduces twist on the cooled fiber, which is a non-permanent, mechanical rotation of the fiber. The system and method uses a diameter measuring device that produces a signal corresponding to the fiber's diameter with respect to time. Since the fiber is slightly elliptical in practice, periodic variations in the diameter measurement signal are detected that reflect the rotation imparted into the fiber. The signal is further processed to provide data regarding the effect of the rotations introduced into the fiber, namely the twist and spin present in the fiber.

摘要： The present disclosure provides systems and methods for detecting and interpolating still pixels. In certain embodiments, the systems and methods establish a still pixel level for each still pixel, and using that still pixel level, provide an interpolation procedure for determining the pixel value of a selected pixel at a frame a distance α from frame F(t−1). Disclosed embodiments are capable of providing motion compensated interpolation results for a wide variety of circumstances, including cases where the endpoints of the motion vector of a selected pixel to be interpolated vary between substantially still and not still, as well as cases where mixtures of temporal and motion compensation interpolations are necessary.Still pixel candidates may be refined in a process where pixels that may be properly handled by standard motion compensation interpolation techniques are eliminated. Further, still pixel candidates may be flagged as high or low likelihood to further enhance confidence in the detected still pixels.

摘要： A one-pass picture-layer rate control (RC) method and system for controlling a video encoder: The bit allocation and determination of quantization parameter (QP) in this rate control method and system are based on a Rate-Quantization (R-Q) scale model. The R-Q model is a linear one, wherein the number of bits per picture is in reverse ratio of quantization scale for that picture. A conversion of exponential-based QP to linear-scaled QP is taken in the calculation of complexity model and determination of QP. The conversion is integer-based and is consistent with the quantization array defined in the H.264 standard.
