|
The more compressed the file, the more noticeable that data has been removed.
|
|
Lossy compression
|
|
|
Lossless compression
|
|
|
Both lossy and lossless compression
|
|
|
None of the above
|
Explanation:
Detailed explanation-1: -No quality degradation happens in lossless compression. Lossy compression reduces the size of a file to a large extent. Lossless compression reduces the size but less as compared to lossy compression. Transform coding, Discrete Cosine Transform, Discrete Wavelet transform, fractal compression, etc.
Detailed explanation-2: -Lossy compression reduces an image file size by permanently removing less critical information, particularly redundant data. Lossy compression can significantly reduce file size, but it can also reduce image quality to the point of distortion, especially if the image is overly compressed.
