In order to obtain high compression ratio and high-quality images that can be randomly stored under the condition of efficient encoding and compression, MPEG defines three frame types, namely: ( )
A: I-frame
B: P-frame
C: B-frame
D: T-frame
A: I-frame
B: P-frame
C: B-frame
D: T-frame
举一反三
- The I-frame is implemented using a JPEG-like coding method. It does not use any other frame as a reference, but only performs spatial redundancy compression within the frame. ( )
- The I-frame is implemented using a JPEG-like coding method. It does not use any other frame as a reference, but only performs spatial redundancy compression within the frame. ( ) A: 正确 B: 错误
- MJPEG encoding compression technology is a dynamic image compression method based on the development of static image compression technology, which can compress continuous video streams to produce an image sequence. Its advantages are: ( ) A: Relatively simple to implement B: Encoding delay is small C: The picture can be spliced arbitrarily (the picture does not matter directly) D: Can flexibly adjust the compression frame rate and resolution
- An animation of a small ball falling, we will record the beginning and end of the ball movement as____. A: key frame B: subdivision frame C: transition frame D: intermediate frame
- What are the main types of body? A: separate frame construction B: individual frame construction C: unitized body construction D: modified body construction
