37 results about "Letter recognition" patented technology

A recognition letter, or letter of recognition, can be written for many different situations, both business and personal. They are very similar in purpose to "commendation letters" but the term is used more often in the public and not-for-profit sectors. Often a recognition letter will lead to a formal commendation letter.

Apparatus and method for letter recognition

Disclosed is a letter-recognition apparatus and method for recognizing a language letter inputted in a pen drag direction without a special operation for switching a language mode in a terminal equipped with a touch screen. A user interface having a plurality of letter input areas displayed on the touch screen is provided. The letter input areas have first language consonant letters that are divided into a plurality of pairs of basic consonant letters and extended consonant letters of a first language assigned thereto. The basic consonant letters and the extended consonant letters of the first language are mapped and assigned to basic consonant letters and extended consonant letters of a second language. One of the consonant letters assigned to a letter input area corresponding to a touch pen input according to a type of the touch pen input is selected when the touch pen input is present on the letter input areas, such that a display unit displays the selected consonant letter. When the touch pen input is present on the letter input areas and the touch pen input type is a pen drag in a vowel letter direction, the display unit displays a previously assigned vowel letter of the first language according to the vowel letter direction.

Method for positioning mobile robots on basis of digital letter recognition

The invention provides a method for positioning mobile robots on the basis of digital letter recognition. The method includes manufacturing identification pictures and setting number identification for acquiring coordinate information and angle identification for acquiring direction and angle information on the identification pictures; placing working regions of the robots in world coordinate systems, laying a plurality of identification pictures in each working region and creating number identification-coordinate comparison tables; recognizing the number identification when the identificationpictures are photographed in robot advancing procedures, comparing the number identification to the number identification-coordinate comparison tables and acquiring the coordinate information corresponding to the current number identification; recognizing the angle identification and acquiring current advancing directions of the robots and deviation angles relative to the world coordinate systems. The method has the advantages that identification, which contains the coordinate information, in the identification pictures is digital letters, accordingly, sufficient number information can be acquired by the aid of the method and is easy and convenient to read, and information can be corrected read without alignment regardless of scanning at optional angles.

Static sign language letter recognition system and method based on Kinect sensor

ActiveCN103927555AOvercome the problem of high dimensionality of eigenvectorsSegmentation is accurate and effectiveCharacter and pattern recognitionFeature vectorMachine vision
The invention relates to the field of computer vision and intelligent human-machine interaction, in particular to a human-machine interaction system based on machine vision and an interaction method of the system, and provides a method for carrying out static sign language letter recognition based on an improved SURF algorithm by combining a Kinect sensor. The Kinect sensor collects the depth image of a target area to carry out hand pixel area division, and interference caused by illumination changes and complex backgrounds can be eliminated. The improved SURF algorithm is used for extracting feature points, meanwhile, the self-adaption radius r is set, SURF feature points are screened grade by grade in the neighbourhood with r as the radius by comparing the number of the feature points and the feature point distance, the recognition rate is greatly improved, and the robustness of recognition work on the skin color, the illumination changes, the complex backgrounds and other environmental factors, angle changes and scale changes is guaranteed. To solve the problem that SURF feature vector dimensions are high, an SVM one-to-one classification method is adopted, SURF feature descriptors are classified and trained, and a recognition result is obtained.
