摘要:
A method of determining eyeglass frame parameters from a digital image of the person's face and a digital image of an eyeglass frame. The method comprises the steps of: (a) providing a digital image of the person's face; (b) determining a physical scale of the face using a scaling factor; (c) locating center points P1, P2 of the left and right irises in the face image, and determining a pupil midpoint Pc; (d) providing a digital image of an eyeglass frame; (e) adjusting, if necessary, the size of the frame to the physical scale of the face; (f) combining the frame and face images such that the frame is superimposed on the face; (g) aligning the frame and face in accordance with the frame center point fc and the pupil midpoint Pc; and (h) determining the frame parameters.

A moist smokeless tobacco product for oral use comprises a pre-portioned piece of tobacco material semi-dissolvable, a super-hydrated membrane coating comprising a soluble, non-cross-linked component and an insoluble, cross-linked component, and a texture component. The tobacco material comprises moist smokeless tobacco. The texture component reduces the slipperiness and/or increases the friction of the moist smokeless tobacco product when placed in a user's mouth.

The present invention provides a panchromatic sharpening method of spectral image based on fusion of overall structural information and spatial detail information, comprising: performing brightness linear stretching on a panchromatic image, so as to set the variance of the panchromatic image to be equal to the variance of said spectral image; respectively interpolating N components of the spectral image so as to generate an interpolation image series having the same resolution as that of the panchromatic image; subtracting the interpolation image series from the panchromatic image after said linear stretching to obtain difference images; performing Gauss filtering on the difference images, thereby obtaining difference tendency images; and, respectively subtracting the difference tendency image series from the panchromatic image after said linear stretching, thus obtaining fused images. The method can maintain both spectral fidelity and texture detail fidelity of the fused images, support high computation speed, and has wide applicability.

The present invention relates to a tyrosine kinase-inducible domain (pKID) and uses thereof. An isolated polypeptide comprising the pKID, and an isolated polynucleotide comprising a nucleic acid sequence encoding the pKID are provided. Also provided are methods for determining tyrosine kinase and/or phosphatase activity in a sample and for identifying an agent that inhibits a tyrosine kinase or phosphatase using a polypeptide comprising the pKID.

A broadband dual-polarized omni-directional antenna and a feeding method using the same are provided. By setting a vertically polarized antenna and a horizontally polarized antenna each in co-axial, the horizontally polarized antenna is attached to an upper surface and a lower surface of the attaching plate respectively by two arms of a folded dipole and the two arms connect to an inner conductor and an outer conductor of a feed line so that the dual-polarized antenna may have a comparatively broad bandwidth. At the same time, since the dual-polarized ceiling antenna has a good isolation effect and coverage balance, it may work as the MIMO antenna in the LTE and WLAN systems effectively and may be used in the 2G and 3G networks to improve the data transmission rate.
