The present invention discloses a method for adsorbing a straight line/line segment in an image, including: presetting a straight line/line segment, dragging the straight line/line segment by selecting a first part of the line segment, and when a second part of the straight line/line segment is dragged to the vicinity of a line segment in an image, setting the preset line segment to be superposed with the line segment, the vicinity referring to that a minimum distance between the second part of the straight line/line segment and the line segment meets a preset rule. In the present invention, by means of the foregoing technical solution, a user can be conveniently assisted, according to a line segment that exists in an image, to define a polygon frame, so that subsequent image processing can be conveniently performed.

A multi-character continuous handwriting input method where a character is written on a touch unit and after an icharacter is written, an (i+1)character is written in an overlapping manner on the icharacter. When a user is writing, it is determined whether a current stroke belongs to the icharacter or (i+1)character; if it is the (i+1)character, the display color of the icharacter is dimmed automatically, so that the user clearly sees the newly written character on a display screen. Multiple characters can be written continuously without pauses and when an (i+2)character is written, the icharacter disappears automatically from the screen, and the color of the (i+1)character is dimmed automatically. Thus, the ability to continuously write multiple handwritten characters on a screen and the corresponding recognition and display processing significantly improves the input efficiency of handwritten text.

A text image trimming method, according to the following steps: step 1, obtaining text image data; step 2, using straight line detection method to detect the straight lines of the text image, obtaining edges of a trimmed quadrangle; step 3, detecting text on the image data, obtaining the coordinates of the boundary points of a text region; and step 4, obtaining the final trimming result according to the results of steps 2 and 3. The method can automatically detect the edges of the text region and utilize the detected text region to verify and remove unrelated redundant information thereby, allowing the user to only see the portion containing the text region useful to the user when viewing image data.

An overlapped handwriting input method, which includes: moving a touch unit on a touch screen, recording and displaying the track of a stroke on a handwriting area of the screen; determining whether the stroke currently being written and all previously input strokes having a color A belong to the same character; if yes, keeping the current stroke color unchanged; otherwise, determining whether an inactive visual layer character is present on the screen; if yes, clearing an image of the inactive character and related stroke information; otherwise, defining as the inactive character all strokes having the color A, excluding the current stroke; submitting data of the current inactive character to a recognition engine, and outputting a recognition result. Thus, the interface friendliness for users to continuously input handwriting according to their natural writing practice is ensured, and multiple handwritten characters can be written continuously without pause, thereby improving handwriting input efficiency.

Provided in the present invention are method and system for delivering an electronic business card by combining geographical location information and Bluetooth technology. The method comprises: a requesting user submitting the current geographical location information, the name of a Bluetooth communication device, and a list of the names of other detected Bluetooth communication devices to an electronic business card delivery server by using a mobile client, acquiring a list of users corresponding to neighboring mobile clients as well as the user's condensed identity information, the neighboring mobile clients being located within a predetermined distance range and located within a detection range of the Bluetooth communication device; selecting a user from the user list, sending an electronic business card delivery request to the electronic business card delivery server; the electronic business card delivery server transmitting the request to the mobile client corresponding to the selected user, and when receiving corresponding confirmation information, responding to the request so as to deliver the electronic business card. Compared with the prior art, the present invention allows for the delivery of large quantity of electronic business cards, simplified operations, and ensured accuracy and security of electronic business card contents.
