The invention discloses a text detection and recognition method combining character level and character string level classification. According to the method, pixel sets possibly belonging to the same character are extracted from images to form alternate characters; alternate characters which do not meet the geometric feature statistic rule are filtered out; a character level classifier based on the character rotation and dimension invariance features is adopted for classifying the alternate characters, and the probability that the alternate characters are certain characters is determined; the characters are combined two by two, and initial character strings are formed; the similarity between every two character strings is calculated, two character strings with the highest similarity are combined into new character strings until no character strings capable of being combined exist; a character level classifier based on the character string structure feathers is adopted for classifying the character strings to determine the character strings with semanteme; and the probability that character strings to be recognized are certain characters is utilized for recognizing the character strings, and the semantic text is obtained. The text detection and recognition method has the advantages that the text detection and recognition process is used as a whole, the interaction of the text detection and the recognition is utilized for improving the result precision, and simplicity and high efficiency are realized.

A method and system for achieving accurate segmentation of characters with respect to a license plate image within a tight bounding box image. A vehicle image can be captured by an image capturing unit and processed utilizing an ALPR unit. A vertical projection histogram can be calculated to produce an initial character boundary (cuts) and local statistical information can be employed to split a large cut and insert a missing character. The cut can be classified as a valid and/or a suspect character and the suspect character can be analyzed. The suspect character can be normalized and passed to an OCR module for decoding and generating a confidence quote with every conclusion. The non-character images can be rejected at the OCR level by enforcing a confidence threshold. An adjoining suspect narrow character can be combined and the OCR confidence of the combined character can be assessed.

The invention discloses a character recognition method and system based on a template character library. The character recognition system comprises a camera device and a computer which is connected to the camera device and which is installed with image processing software and character recognition software. The camera device is used for shooting a to-be-recognized character zone of a to-be-measured product, and sending a captured image containing the to-be-recognized character zone to the computer. The computer is used for preprocessing the captured image to obtain a binary image, separating the to-be-recognized character zone from the binary image, performing image segmentation of each to-be-recognized character image in the to-be-recognized character zone, recognizing multiple to-be-recognized character images subjected to segmentation one by one by comparing with the template character library, and showing recognized characters according to a set character recognition sequence. The invention can greatly improve the recognition accuracy and the recognition efficiency of numbers, or letters, or combined characters of numbers and letters, and can be applied to the technical field with extreme high requirements for character recognition accuracy.

The invention discloses a method and a device for generating a dynamic verification code picture. The method comprises the following steps of acquiring a verification code character string; acquiring character image groups according to the verification code character string; processing at least two character image groups in a preset way to acquire at least two corresponding character image groups to be combined respectively; combining character images to be combined in the at least two character image groups to be combined to acquire at least two corresponding static verification code pictures respectively; and combining the static verification code pictures to acquire a dynamic verification code picture, wherein the at least two static verification code pictures are presented frame by frame through the dynamic verification code picture. According to the method and the device, the dynamic verification code picture with both motion characteristics and fuzzy characteristics can be automatically generated by combining fuzzy processing and rigid body transformation processing, so that difficulty in the verification code identification of a machine is increased, the automatic identification rate is lowered, and the network security is improved.
