Embodiment 1
[0073] figure 1 The method flowchart of the image text recognition that the embodiment of the present invention provides, such as figure 1 As shown, the method may include the following steps:
[0074] Step 101: Obtain the text area in the image to be recognized.
[0075] The server acquires an image containing text information sent by the mobile terminal, and the image may be an original image captured by the mobile terminal. In this step, the server extracts the text area in the image to be recognized. Or, the image may be that after the mobile terminal captures the original image, extracts the text area in the image to be recognized and then sends the text area in the image to be recognized to the server.
[0076] Existing methods can be used to extract the text area, and the text area can be extracted after removing the image background, but not limited to the following methods:
[0077] Method 1. First, perform color run-length coding according to the color Euclidean d...
Embodiment 2
[0155] Figure 5 The structure diagram of the device for image recognition provided by Embodiment 2 of the present invention, such as Figure 5 As shown, the device includes: an area acquisition unit 500 , a text recognition unit 510 , a position recording unit 520 , a layout analysis unit 530 and a semantic analysis unit 540 .
[0156] First, the area acquisition unit 500 acquires the text area in the image to be recognized, wherein the area acquisition unit 500 can receive the image to be identified sent by the mobile terminal, and extract the text area from the image to be identified; or, the receiving mobile terminal extracts the text area from the image to be identified. and send it to the textarea.
[0157] The character recognition unit 510 respectively recognizes each character block in the character region, and an existing recognition method may be adopted, for example, specifically including: binarizing the character region; dividing the binarized character region i...
