According to the consistency between the original image and the reconstructed image, the encoding techniques are divided into ______ compression and ______ compression.
lossless:)lossy
举一反三
- Evaluation criteria of video image coding and compression technology ( ) A: Bit rate B: Reconstructed image quality C: Encoding / decoding delay D: The capability of error repair
- The difference between hard compression and soft compression in DVR is "who completed the encoding compression?" If it is done by the hardware chip on the board, it is called hard compression. If it is handed over to the CPU to complete, it is called soft compression. ( )
- The difference between hard compression and soft compression in DVR is "who completed the encoding compression?" If it is done by the hardware chip on the board, it is called hard compression. If it is handed over to the CPU to complete, it is called soft compression. ( ) 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
- Since the video encoding process requires unidirectional or bidirectional reference prediction, the order of image compression, transmission, and display is not consistent. ( )
