Fourier transform can be used in image compression.
举一反三
- According to the consistency between the original image and the reconstructed image, the encoding techniques are divided into ______ compression and ______ compression.
- In the block transform coding system, the quantization operation achieves the image 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. ( )
- 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
- 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
