Abstract: Disclosed are a shield tunnel segment structure and a construction method thereof. The shield tunnel segment structure includes segment blocks sequentially spliced in a circumferential direction. Each segment block forms a closed annular segment structure, and outer diameters of adjacent annular segment structures gradually increase in an axial direction. At least two adjacent segment blocks of the same annular segment structure form an annular inner groove, and at least one segment block of the adjacent annular segment structures is provided with an inner bump which matches the annular inner groove. At least two adjacent segment blocks of the same annular segment structure form an annular outer groove, and at least one segment block of the adjacent annular segment structures is provided with an outer bump which matches the annular outer groove. The annular outer grooves and the annular inner grooves are staggered in the circumferential direction.

Abstract: The present disclosure provides an information processing method and apparatus, a terminal, and a storage medium. The information processing method, comprising: in response to a first operation event for a target entity word in displayed content, acquiring target entity word information associated with the target entity word, wherein the target entity word information comprises first information and second information, the first information comprising the meaning of the target entity word, and the second information comprising a communication identifier of a communication group or contact associated with the target entity word; and displaying the target entity word information. According to the present disclosure, the meaning of the target entity word is displayed, and the communication group or contact associated with the target entity word is displayed, such that the user can quickly define the group or contact associated with the target entity word.

Abstract: A method and apparatus for recognizing a character area in an image are provided. A specific embodiment of the method comprises: acquiring color values and position information of pixel points in a to-be-recognized image; clustering the pixel points based on the color values of the pixel points, the color values of the pixel points in each pixel point category being identical or similar; determining, for each category of clustered pixel points, outlines of connected regions including the pixel points in each category of pixel points, to obtain an outline set; and merging, based on the color values and the position information of the outlines in the outline set, the outlines, to obtain character areas in the image. The embodiment has improved the accuracy of recognizing character lines in recognizing characters in an image.
