Abstract: An image processing method and apparatus for a smart pen, and an electronic device are provided in embodiments of the present disclosure, and belong to the technical field of data processing. The method comprises: monitoring a working state of a second pressure switch provided at a pen tip of a smart pen after a first pressure switch of the smart pen is in a closed state; controlling an image collection module on the smart pen to collect a reflected infrared signal from an area where the smart pen writes; performing feature extraction processing on an original image to obtain a feature matrix corresponding to the original image; determining, based on current load status of the smart pen, the number of convolutional layers used for convolution processing in parallel convolutional layers; and adding current time information to a trajectory classification result to form a time-ordered trajectory vector.

Abstract: The present disclosure provides an Internet teaching platform-based following teaching system. By using a recording and broadcasting system of an Internet teaching platform, recording class teaching of a standard teacher and then performing standardization segmentation processing on data of the recorded class teaching, a standard teaching recorded and broadcast course is formed, and after learning the standard teaching recorded and broadcast course, a following teacher can imitate the standard teacher to perform local class teaching, which is also recorded by means of the recording and broadcasting system. By using the system of the present disclosure to perform processing of relationship construction, statistics, analysis and comparison on a variety of collected data, the recording and guiding before, during and after a teaching process of the following teacher can be realized, so as to facilitate the following teacher in effectively completing the local class teaching.

Abstract: Provided in the present disclosure are a network-based online interactive language learning system and method, the learning system comprising: a server host and multiple clients, wherein each of the clients transmits data in real time to the server host via an input device, and sends information from the server host to a user by virtue of an output device of each of the clients. With the system and method of the present disclosure, when using the teaching system of the present disclosure, different learners can interact with other learners at the same level, and the mother tongues of one of the two parties in interacting are target learning languages of the other party, thus quickly improving language communication ability.

Abstract: The present disclosure provides effective recording and broadcasting method and system. The recording of function operation of using multimedia whiteboard, speech/speaking voice, communication voice for communication with other users and/or guiding etc. by user during network teaching or online conference is realized, and different data streams are formed respectively, the various data streams are labeled with unified time stamp created by network teaching system, which replaces completely recording the whole event in streaming media format. In this way, network users can conveniently download various data streams to be broadcasted from cloud server or local area network server through network anytime and anywhere, after acquiring data stream, client on user terminal reproduces the acquired data stream according to time stamp and organically combines them to broadcast and displays them to user, thereby finishing broadcasting on demand and browsing.
