In this paper, an improved method of constructing multiple quasi-orthogonal spreading codes and a new modulation and demodulation scheme based on position mapping are proposed on the research of methods of constructing multiple quasi-orthogonal codes, using new method of codes grouping and position mapping, and making the demodulating of the quasi-orthogonal branches into the combination of demodulating of orthogonal sequences codes, that will obtain better demodulation performance.
Unlike the case of usual framework, the new strategy is: the invariant vectors are only used to object registration. First the feature matching is used to search targets relationship between test and reference image, and then, depending on this relationship, reference image is recovered to the same coordinate system of the test image by an affine transformation.
The key technique of this novel framework is to design an effective affine invariant vector, which has the capability of object registration and is unaffected by image noise, detail changing and target aberrance.
Then we design a labeling position matrix of embedding watermark using the high frequency matrix of image multi - resolution. Digital watermark is embedded into the low frequency domain by the labeling position matrix which maps the low frequency matrix of the image multi - resolution.
A three-dimensional in-situ calibration procedure was used to determine the relationships between the 2-D image planes and three-dimensional object fields for both position mapping and velocity three-component reconstruction.
TL receptive fields were always found close to the equator of this field, with their naso-temporal position mapping onto the rostro-caudal axis of TL.2.The second type of activity was a bursting discharge synchronized with saccadic eye movements.
The objective of this project was to develop and evaluate a data logging system attached to a precision seeder to enable high accuracy seed position mapping of a field of sugar beet.
Even with these precautions, tiny vertical bead motions or instrumental drift can introduce errors in position mapping.
He then mapped player position to Color and removed the X-position mapping in order to get a freely manipulable workspace.
in many fields,a three-dimensional object must be reconstructed from serial eras-sectionimages,either to aid in the comprehension of the object structure or to facilitate itS automatic manipulationand analysis. Becaues of the restriction of the numbers of serial cross-section images, the procedure ofinterpolation is necessary for obtaining a three-dimensional object with high quality. In this peper,a newinterpolation algorithm-position mapping is proposed. The experimental resultS show itS good performance.
