Compression Techniques

What is the purpose of compression?

• To increase the size of files

• To store more files on hard drives

• To slow down the transmission of files

• To make files more complex

Which compression technique reduces repeated information?

• Run-Length Encoding

• Dictionary Coding

• Perceptual Coding

• Lossy Compression

What is the advantage of lossless compression?

• It reduces the file size significantly

• It preserves all the original data

• It improves the quality of the file

• It allows for more efficient transmission

What is the purpose of a Huffman Tree in compression?

• To generate efficient codes for data blocks

• To remove redundant information

• To reduce the precision of data

• To compress audio files

Which compression technique takes advantage of human perception?

• Run-Length Encoding

• Dictionary Coding

• Perceptual Coding

• Lossy Compression

What is the main advantage of lossy compression?

• It reduces the file size significantly

• It preserves all the original data

• It improves the quality of the file

• It allows for more efficient transmission

Which sense is perceptual coding based on?

• Hearing

• Sight

• Taste

• Touch

What is the purpose of discarding high-frequency spatial data in image compression?

• To reduce the file size

• To improve the visual quality

• To increase the precision of the image

• To compress audio files

What is the advantage of video compression?

• It reduces the file size significantly

• It preserves all the original data

• It improves the quality of the video

• It allows for more efficient transmission

What is temporal redundancy in video compression?

• The repetition of similar patches between frames

• The removal of high-frequency spatial data

• The encoding of differences between patches

• The compression of audio data
