The invention relates to a handwriting signature identification equipment and a method thereof. The equipment comprises a video collection module, an initialization module and a feature extraction module, wherein, the video collection module is used for collecting a group of handwriting signature visual images; the initialization module is used for obtaining high-quality images to be detected by utilizing the handwriting signature visual images collected; and the feature extraction module is used for extracting the features of the images to be detected so as to provide convenience for classifying and judging the effectiveness of the images. By combining video collection, initialization process and image feature extraction, processing modules are embedded into a camera, and the equipment and the method of the invention realize a handwriting signature identification system with low cost, convenient use and small network burden.

The disclosed architecture is a new feature extraction approach to handwriting recognition. Given an handwriting sample (e.g., from an online source), a sequence of time-ordered dominant points are extracted, which include stroke-endings, points corresponding to local extrema of curvature, and points with a large distance to the chords formed by pairs of previously identified neighboring dominant points. At each dominant point, a multi-dimensional feature vector is extracted, which includes a combination of coordinate features, delta features, and double-delta features.

The invention provides a hand-held terminal with the handwriting recognition and identity validation function and a realizing method, which belongs to the electronic equipment field and relates to the hand-held terminal which is realized via handwriting recognition and the assorted realizing method. The terminal comprises a handwriting input structure, a handwriting recognition module and a handwriting recognition authority management module. The users can input handwriting of own in the hand-held terminal by utilizing the handwriting input structure in the invention, and can effectively be processed identity validation by the handwriting recognition module, thereby the authority of the users to enter the hand-held terminal can be determined; the users need not clearly remember the password, only need handwriting recognition to process authority recognition, and in the state of guaranteeing privacy and safety of the hand-held terminal, a great convenience is brought for the users.

The present invention discloses a character recognition method and a stylus. The character recognition method comprises the following steps of: acquiring handwriting data of the stylus in the writing process; according to the handwriting data, extracting numerical characteristic information of each character; and acquiring standard characteristic information of pre-stored characters, and according to the standard characteristic information, recognizing characters corresponding to the extracted numerical characteristic information of each character. According to the character recognition method and the stylus, electronization of paper documents can be implemented; long-term storage of written contents is facilitated and subsequent inquiry is convenient; the written contents are not required to input into intelligent terminals such as a computer and the like in a manual mode, so that input workload is greatly reduced.

The present invention discloses a writing display method and a system thereof, which are applied to an intelligent interactive panel. The method comprises the steps of: obtaining current location information of the pen tip in real time when the user writes on the intelligent interactive panel; according to the current location information and the width of the screen of the intelligent interactive panel, determining a current non-occlusion area relative to the user, on the screen of the intelligent interactive panel; and synchronizing the handwriting corresponding to the current location information to display in the current non-occlusion area. According to the method and system disclosed by the present invention, by synchronizing the writing information in the occlusion area to display in the non-occlusion area, inconvenience that the content of the writing information cannot be viewed in real time due to the occlusion of the user body is solved.

The invention discloses an automatic chalk handwriting wipe-away blackboard which comprises a blackboard body, a slide frame, a board wiper base, a board wiper body, a collecting tank, a water storage cavity, a top rod, a first drive mechanism, a second drive mechanism and a control device. The slide frame comprises a pair of transverse first guide rails and a vertical second guide rail. The collecting tank is connected to the lower side of the board wiper base. The water storage cavity is formed in the board wiper base. A water permeable hole is formed in the lower side of the board wiper base. A diaphragm part is arranged at the water permeable hole and is composed of a pair of rubber pieces. The middle parts of the pair of rubber pieces are overlapped. The top rod is arranged in the collecting tank. When the front side wall makes close contact with the blackboard body, the blackboard body abuts against one end of the top rod, and the other end of the top rod exerts pressure on the diaphragm part so that the middle parts of the pair of rubber pieces can be separated from each other. The control device controls the first drive mechanism and the second drive mechanism to work alternately. Chalk handwriting on the blackboard body is automatically wiped away.
