Method and system for fast making vector font library

The invention relates to a method and a system for fast making a vector font library. The system comprises a computer, a printer and a scanner. The method includes the steps of firstly, appointing character contents of a to-be-built font library and writing the same in a standard form through a machine; secondly, writing characters according to writing standards in the printed standard form through handwriting, and using the standard form as unit to collect the handwriting characters to obtain a plurality of form images; thirdly, segmenting the form images to obtain character closed contours, selecting some points as key points according to the character closed contours, and screening the key points to obtain optimal key point; fourthly, obtaining character vector contours according to the optimal key point, and generating the standard TrueType font library according to the character vector contours. The vector font library made by the method is high in quality, writing style of an original writer can be kept completely, no manual intervention is needed during font library generating, the high-quality standard font library is generated at one step by the scanned images, and batch production of personalized font libraries is facilitated.

Processing method and search method for multiple-source and multi-temporal satellite image tile data

The invention discloses a processing method for multiple-source and multi-temporal satellite image tile data. According to the processing method, a mass tile data organization structure with the time-space characteristic and the multi-source heterogeneous characteristic can be constructed, and metadata of multi-source heterogeneous satellite data tiles can be processed. The processing method comprises the steps of: (1) inputting a plurality of pieces of satellite image data, wherein each satellite image data comprises pixel data and metadata; (2) receiving a data warehousing request; (3) storing each metadata based on an image metadata table of BeyonDB, wherein each row of record description of the image metadata table comes from the metadata of the tile data of the same satellite image, and a plurality of pieces of tile data correspond to the same satellite metadata record; and (4) processing the pixel data by adopting a transverse blocking and longitudinal layering tile structure, and storing the mass tile data after processing the mass tile data by adopting a multiple-source and multi-temporal pyramid tile data file tree structure. The invention also provides a processing system, as well as a search method and a search system based on the processing system.

Information recommendation method and apparatus, computer device and storage medium

The invention provides an information recommendation method. The method comprises the steps of obtaining image information, and according to the image information, generating a user tag set corresponding to user identifiers, wherein the image information has the corresponding user identifiers; according to user tags in the user tag set and the corresponding image information, forming eigenvectorscorresponding to the user identifiers; inputting the eigenvectors to a trained information recommendation model, and outputting recommendation parameters of users for to-be-recommended information; and according to the recommendation parameters, recommending the to-be-recommended information to terminals corresponding to the user identifiers. The user tag set capable of reflecting user features isestablished through the image information; the recommendation parameters of the users for the recommended information are predicted by adopting the trained information recommendation model accordingto the user tag set; and the recommendation is performed according to the recommendation parameters, so that the recommendation accuracy is improved and the users not interested in the information areprevented from being disturbed. In addition, the invention provides an information recommendation apparatus, a computer device and a storage medium.
