Compounds for RNA capping and uses thereof

A cyclohexene compound and use thereof, which relates to the technical field of pharmaceutical chemistry is provided. The cyclohexene compound is the cyclohexene compound having a structural formula I or a pharmaceutically acceptable salt, an ester group prodrug or a stereoisomer thereof. It is verified by activity assay for influenza NA that the cyclohexene compound has a great inhibiting activity against both wild-typed and drug-resistant influenza viruses, and the inhibiting activity ICof some compounds against wild-typed and drug-resistant influenza viruses is lower than 5 nM, showing significant inhibiting effect on influenza viruses. This shows that the cyclohexene compound or a pharmaceutically acceptable salt or a stereoisomer thereof has superior application prospect on preparing anti-influenza drugs, thereby providing a new drug choice for treating influenza clinically.

Cyclohexene compounds and use thereof

Provided is a character segmentation and recognition method. The method includes: collecting image data to obtain a to-be-recognized image; positioning a character line candidate region on the to-be-recognized image; obtaining pre-set character line prior information, where the character line prior information includes the number of characters, character spacing and a character size; obtaining a corresponding segmentation point template based on the character line prior information; obtaining credible degrees of different positions on the character line candidate region traversed by the segmentation point template; determining a position with the highest credible degree as an optimal segmentation position; segmenting the character line candidate region based on the segmentation point template and the optimal segmentation position to obtain multiple single character regions; and performing character recognition on each of the single character regions to obtain a corresponding recognition result.

Character segmentation and recognition method

The present invention relates to a character recognition method. Same comprises: step 1: reading in a character image; step 2: image preprocessing; step 3: character splitting; step 4: edge extraction; utilizing an edge detection operator to detect edge points of characters; step 5: feature extraction, where the features of each edge point of each character are all expressed with distances running from other edge points of the character to the edge point and are represented by eigenvectors (P, P, . . . P); step 6: feature processing, mapping the eigenvectors (P, P, . . . P) into a matrix, T, thus allowing all characters to be identical in eigenvector dimension; and, step 7: template matching recognition. Because the features of each edge point of the characters are all expressed with the distances running from the other edge points to the edge point, the entirety of the features are ensured for the characters, and the difference in features are expanded for different characters, thus increasing character recognition accuracy.

Character recognition method

A valuable document authentication method and device. Whether a valuable document, an image sensor or a first sensor has shifted or not, the effect of authenticating the valuable document will not be affected, because a reference unit is needed to determine the location relationship between the image sensor and the first sensor before the valuable document is authenticated, thereby preventing an error occurring with the authenticated valuable document due to the fact that each sensor has shifted; moreover, when the valuable document is authenticated, even if the valuable document has shifted, the correctness of the valuable document authenticated can also be guaranteed by the conversion of the location relationship between a detection object and the sensor. Therefore, the solution provided in the present invention improves the identification accuracy and working efficiency of the authentication device, thereby providing convenience for users.

Valuable document authentication method and device

The present invention relates to a recognition method and a recognition device for a sheet-type medium. The method comprises: step, collecting image information; step, splitting from the image information collected image information of an object-to-be-recognized; step, reconstructing image data of a feature area, extracting a feature on the reconstructed image data, and forming an eigenvector; and, step, sending the eigenvector into a standard data-trained classifier, and acquiring a recognition result. The method has an image reconstructed on the basis of feature area prior information, improves image quality, facilitates increased recognition accuracy, and, because only the image area that requires feature extraction is reconstructed, reduces storage space consumption. This not only saves large amounts of storage space and time and increases resource utilization rate, but also increases recognition accuracy and achieves an improved balance between resource and efficiency.
