Detailed explanation-1: -Which of the following is a true statement about data compression? Regardless of the compression technique used, once a data file is compressed, it cannot be restored to its original state.
Detailed explanation-2: -Image compression is an application of data compression that encodes the original image with few bits. The objective of image compression is to reduce the redundancy of the image and to store or transmit data in an efficient form.
Detailed explanation-3: -The objective of image compression is to reduce irrelevance and redundancy of the image data to be able to store or transmit data in an efficient form. It is concerned with minimizing the number of bits required to represent an image. Image compression may be lossy or lossless.
Detailed explanation-4: -Lossless compression restores and rebuilds file data in its original form after the file is decompressed. For example, when a picture’s file size is compressed, its quality remains the same. The file can be decompressed to its original quality without any loss of data.
