Syllabus

• Week 1

  Digital image and video

  • What is digital media technology?

    Compared with traditional media, digital media has the advantages of interactive and fast transmission through the network.

  • Digital image technology

    A digital image is an image obtained by digitizing an analog image, with pixels as basic elements, and can be stored and processed by a digital computer or digital circuit.

  • Digital video technology

    Digital video is video recorded in digital form, as opposed to analog video. Digital video has different ways of generation, storage and broadcasting.

• Week 2

  Digital audio

  • Fundamentals of digital audio technology

    Digital audio is a technology that uses digital means to record, store, edit, compress or play sound.

  • Digital speech processing

    Digital speech processing mainly studies the speech production process, the statistical characteristics of speech signals, automatic speech recognition, machine synthesis and speech perception.

  • Typical applications of digital speech processing

    Speech recognition technology is a technology that enables machines to understand and recognize human speech. It has a wide range of application scenarios in many fields.

• Week 3

  Digital media compression

  • Intruduction to data compression

    Without losing useful information, reducing the amount of data can reduce storage space and improve its transmission, storage and processing efficiency.

  • Digital image compression

    Since the amount of image data is huge, it is very difficult to store, transmit and process, so digital image compression is very important.

  • Digital video compression

    Encoding and compressing the original video can remove redundancy in spatial and temporal dimensions.

  • Digital audio compression

    Digital audio compression compresses the audio data signal as much as possible while ensuring that the signal does not produce auditory distortion.

• Week 4

  Computer graphics and animation

  • Computer graphics

    Computer graphics mainly studies how to represent graphics in computers, and how to use computers to calculate, process and display graphics.

  • Computer animation

    Unlike traditional animation techniques which use frame-by-frame animation of 2D illustrations, computer animation generates continuous image frames by building 3D models.

  • Computer game

    The emergence of various game engines has greatly facilitated game developers. They can provide game designers with various tools needed to write games, allowing game designers to easily and quickly create game programs.

• Week 5

  Computer vision and information visualization

  • Overview of computer vision

    Computer vision refers to the use of cameras and computers to identify, track and measure targets instead of human eyes.

  • Visual big data

    Visual data information has more mixed characteristics than other big data information, so the authenticity of the data is particularly important.

  • Information visualization

    Information visualization is the application of visualization technology in the field of data. Information visualization technology is widely used in various fields such as finance, network communication, biology and e-commerce.

• Week 6

  Digital media network

  • Digital media storage

    Data storage refers to saving media data on certain media in a reasonable, safe and effective manner according to different application environments and ensuring effective access.

  • Digital media transmission

    Transmission media is also called transmission medium or transmission medium. It is the physical path between the sender and the receiver in the data transmission system.

  • Digital media network security

    With the advent of the digital age, the information security and protection of digital content have become topics of extensive research by many scholars.
